Replaced the messy GNU-styled, multi-lingual documents with a single Markdown README.md. Added the GitHub repository to the document and removed the SourceForge website, my web page, and the SourceForge mailing list from the document. Removed the document license, and my PGP key from the package. Removed the signature file from the repository. Changed the license from GPLv3 to APLv2. Various fixes to avoid JetBrains IDE problem detection.

                    GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
                            Preamble
  The GNU General Public License is a free, copyleft license for
 software and other kinds of works.
  The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
 the GNU General Public License is intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
 software for all its users.  We, the Free Software Foundation, use the
 GNU General Public License for most of our software; it applies also to
 any other work released this way by its authors.  You can apply it to
 your programs, too.
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
  To protect your rights, we need to prevent others from denying you
 these rights or asking you to surrender the rights.  Therefore, you have
 certain responsibilities if you distribute copies of the software, or if
 you modify it: responsibilities to respect the freedom of others.
  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must pass on to the recipients the same
 freedoms that you received.  You must make sure that they, too, receive
 or can get the source code.  And you must show them these terms so they
 know their rights.
  Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify it.
  For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software.  For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.
  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.
  The precise terms and conditions for copying, distribution and
 modification follow.
                       TERMS AND CONDITIONS
  0. Definitions.
  "This License" refers to version 3 of the GNU General Public License.
  "Copyright" also means copyright-like laws that apply to other kinds of
 works, such as semiconductor masks.
  "The Program" refers to any copyrightable work licensed under this
 License.  Each licensee is addressed as "you".  "Licensees" and
 "recipients" may be individuals or organizations.
  To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.
  A "covered work" means either the unmodified Program or a work based
 on the Program.
  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
  1. Source Code.
  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.
  The Corresponding Source for a work in source code form is that
 same work.
  2. Basic Permissions.
  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.
  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Use with the GNU Affero General Public License.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU Affero General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the special requirements of the GNU Affero General Public License,
 section 13, concerning interaction through a network will apply to the
 combination as such.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
 versions of the GNU General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
  15. Disclaimer of Warranty.
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
  17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
                     END OF TERMS AND CONDITIONS
            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.
    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If the program does terminal interaction, make it output a short
 notice like this when it starts in an interactive mode:
    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, your program's commands
 might be different; for a GUI interface, you would use an "about box".
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU GPL, see
 <http://www.gnu.org/licenses/>.
  The GNU General Public License does not permit incorporating your program
 into proprietary programs.  If your program is a subroutine library, you
 may consider it more useful to permit linking proprietary applications with
 the library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.  But first, please read
 <http://www.gnu.org/philosophy/why-not-lgpl.html>.

 reslog Installation Guide
 * Table of Contents
   * System Requirements
   * Installation Instruction
     ** Install with ExtUtils::MakeMaker
     ** Install with Module::Build
 * System Requirements
   1. Perl, version 5.8.0 or above.  reslog uses 3-argument open() to
 duplicate filehandles, which is only supported since 5.8.0.  I have
 not successfully port this onto earlier versions yet.  Please tell me
 if you made it.  You can run perl -v to see your current Perl version.
 If you do not have Perl, or if you have an older version of Perl, you
 can download and install/upgrade it from Perl website.
 http://www.perl.com/
      If you are using MS-Windows, you can download and install
 ActiveState ActivePerl.
 http://www.activestate.com/
   2. Required Perl modules: None.
   3. Optional Perl Modules
    * File::MMagic
          This is used to check the file type.  If this is not
      available, reslog will look for the file executable instead.
      If that is not available, too, reslog will judge the file type
      by its name suffix (extension).  In that case reslog will fail
      when reading from STDIN.
      You can download and install File::MMagic from the CPAN archive
      http://search.cpan.org/dist/File-MMagic/ ,
      or install it with the CPAN shell by running "cpan File::MMagic",
      or install it with the CPANPLUS shell by running
      "cpanp i File::MMagic".
      Debian/Ubandu Linux users can install it by running
      "apt-get install libfile-mmagic-perl".
      Red Hat/Fedora/CentOS Linux users can install it by running
      "yum install perl-File-MMagic".
      FreeBSD users can install it by running
      "ports install p5-File-MMagic".
      ActivePerl users can install it by running
      "ppm install File::MMagic".
      The alternative file.exe for MS-Windows can be obtained from
      the GnuWin32 home page: http://gnuwin32.sourceforge.net/.
      Be sure to save it as file.exe somewhere in your PATH.
          It is preferred to use File::MMagic.  The file executable
      seems to make mistakes occationally.
    * Compress::Zlib
          This is used to support read/write of gzip compressed files.
      It is only needed when gzip compressed files are encountered.
      If it is not available when needed, reslog will try to use the
      gzip executable instead.  If that is not available, too, reslog
      will fail.
      You can download and install Compress::Zlib from the CPAN archive
      http://search.cpan.org/dist/Compress-Zlib/ ,
      or install it with the CPAN shell by running "cpan Compress::Zlib",
      or install it with the CPANPLUS shell by running
      "cpanp i Compress::Zlib".
      Debian/Ubandu Linux users can install it by running
      "apt-get install libcompress-zlib-perl".
      Red Hat/Fedora/CentOS Linux users can install it by running
      "yum install perl-Compress-Zlib".
      FreeBSD users can install it by running
      "ports install p5-Compress-Zlib".
      ActivePerl users can install it by running
      "ppm install Compress::Zlib".
      The alternative gzip.exe for MS-Windows can be obtained from
      the gzip home page: http://www.gzip.org/.
      Be sure to save it as gzip.exe somewhere in your PATH.
    * Compress::Bzip2, version 2 or above
          This is used to support read/write of bzip2 compressed
      files.  It is only needed when bzip2 compressed files are
      encountered.  If it is not available when needed, reslog will
      try to use the bzip2 executable instead.  If that is not
      available, too, reslog will fail.  Notice that older versions
      before 2 does not work, since file I/O compression were not
      implemented yet.
      You can download and install Compress::Bzip2 from the CPAN archive
      http://search.cpan.org/dist/Compress-Bzip2/ ,
      or install it with the CPAN shell by running "cpan Compress::Bzip2",
      or install it with the CPANPLUS shell by running
      "cpanp i Compress::Bzip2".
      Debian/Ubandu Linux users can install it by running
      "apt-get install libcompress-bzip2-perl".
      Red Hat/Fedora/CentOS Linux users can install it by running
      "yum install perl-Compress-Bzip2".
      FreeBSD users can install it by running
      "ports install p5-Compress-Bzip2".
      ActivePerl users can install it by running
      "ppm install Compress::Bzip2".
      The alternative bzip2.exe for MS-Windows can be obtained from
      the bzip2 home page: http://www.bzip.org/.
      Be sure to save it as bzip2.exe somewhere in your PATH.
    * Term::ReadKey
          This is used to display the progress bar.  Without this
      reslog will not display the progress bar, but nothing else is
      different.  The progress bar is a good visual representation of
      what reslog is currently doing.
      You can download and install Term::ReadKey from the CPAN archive
      http://search.cpan.org/dist/TermReadKey/ ,
      or install it with the CPAN shell by running "cpan Term::ReadKey",
      or install it with the CPANPLUS shell by running
      "cpanp i Term::ReadKey".
      Debian/Ubandu Linux users can install it by running
      "apt-get install libterm-readkey-perl".
      Red Hat/Fedora/CentOS Linux users can install it by running
      "yum install perl-TermReadKey".
      FreeBSD users can install it by running
      "ports install p5-Term-ReadKey".
      ActivePerl users can install it by running
      "ppm install Term::ReadKey".
 * Installation Instruction
    If you are upgrading from reslog 3.10 or earlier, or if you are
 upgrading from reslog.pl 3.02 or earlier, please read UPGRADE for some
 upgrade instruction.
 ** Install with ExtUtils::MakeMaker
    reslog uses standard Perl installation with ExtUtils::MakeMaker.
 Follow these steps:
    % perl Makefile.PL
    % make
    % make test
    % make install
    When running make install, make sure you have the priviledge to
 write to the installation location.  This usually requires the root
 priviledge.
    If you are using ActivePerl under MS-Windows, you should use
 nmake instead of make. nmake can be obtained from the Microsoft FTP
 site.
 ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe
    If you want to install into another location, you can set the
 PREFIX.  For example, to install into your home when you are not
 root:
    % perl Makefile.PL PREFIX=/home/jessica
    Refer to the docuemntation of ExtUtils::MakeMaker for more
 installation options (by running perldoc ExtUtils::MakeMaker).
 ** Install with Module::Build
    You can install with Module::Build instead, if you prefer.
 Follow these steps:
    % perl Build.PL
    % ./Build
    % ./Build test
    % ./Build install
    When running ./Build install, make sure you have the priviledge to
 write to the installation location.  This usually requires the root
 priviledge.
    If you want to install into another location, you can set the
 --prefix.  For example, to install into your home when you are not
 root:
    % perl Build.PL --prefix=/home/jessica
    Refer to the docuemntation of Module::Build for more
 installation options (by running perldoc Module::Build).

 reslog 安装指南
 ◎目录
  ◎系统需求
  ◎安装指南
    ◎◎以 ExtUtils::MakeMaker 安装
    ◎◎以 Module::Build 安装
 ◎系统需求
   1. Perl 5.8.0 或以上。 reslog 使用三参数的 open() 以复制档案操作，
 我还不知道怎么改写到更早的版本上执行。若你可以改写到更早的版本上执行，
 请告诉我。你可以输入 perl -v 查询你目前的 Perl 版本。目前大多数的 Unix
 系统都有 Perl 。如果你没有 Perl 或需要升级，可以到 Perl 网站下载安装最
 新版 Perl 。
  http://www.perl.com/
      若你用 MS-Windows ，可以下载安装 ActiveState 公司的 ActivePerl 。
  http://www.activestate.com/
   2. 需搭配的 Perl 模组：无。
   3. 选配的 Perl 模组：
     * File::MMagic
          这是检查档案类型用的。若没有安装， reslog 会试著去找 file 程
      式代替。若还找不到， reslog 会改用档尾（副档名）判断档案类型。这
      时若从标准输入读档， reslog 会无法判断。
      你可以由 CPAN 模组库下载安装 File::MMagic ：
      http://search.cpan.org/dist/File-MMagic/ ，
      或用 CPAN Shell 执行 cpan File::MMagic 安装，
      或用 CPANPLUS Shell 执行 cpanp i File::MMagic 安装。
      若你是 Debian/Ubandu Linux 使用者，可以执行
      apt-get install libfile-mmagic-perl 安装。
      若你是 Red Hat/Fedora/CentOS Linux 使用者，可以执行
      yum install perl-File-MMagic 安装。
      若你是 FreeBSD 使用者，可以执行
      ports install p5-File-MMagic 安装。
      若你是 ActivePerl 使用者，可以执行
      ppm install File::MMagic 安装。
      若你要在 MS-Windows 下使用 file.exe 程式，可以由
      GnuWin32 网站下载： http://gnuwin32.sourceforge.net/ 。
      请确认下载后，存档在系统的路径下，档名为 file.exe 。
          建议用 File::MMagic 。 file 程式偶尔会误判。
     * Compress::Zlib
          这是处理 gzip 压缩档用的，只有处理 gzip 压缩档时才会用到。若
      要用时没有安装， reslog 会试著改用 gzip 程式代替。若还找不到，
      reslog 就无法执行。
      你可以由 CPAN 模组库下载安装 Compress::Zlib ：
      http://search.cpan.org/dist/Compress-Zlib/ ，
      或用 CPAN Shell 执行 cpan Compress::Zlib 安装，
      或用 CPANPLUS Shell 执行 cpanp i Compress::Zlib 安装。
      若你是 Debian/Ubandu Linux 使用者，可以执行
      apt-get install libcompress-zlib-perl 安装。
      若你是 Red Hat/Fedora/CentOS Linux 使用者，可以执行
      yum install perl-Compress-Zlib 安装。
      若你是 FreeBSD 使用者，可以执行
      ports install p5-Compress-Zlib 安装。
      若你是 ActivePerl 使用者，可以执行
      ppm install Compress::Zlib 安装。
      若你要在 MS-Windows 下使用 gzip.exe 程式，可以由
      gzip 网站下载： http://www.gzip.org/ 。
      请确认下载后，存档在系统的路径下，档名为 gzip.exe 。
     * Compress::Bzip2 第二版以上
          这是支援读写 bzip2 压缩档用的，只有处理 bzip2 压缩档时才会用
      到。若要用时没有安装， reslog 会试著改用 bzip2 程式代替。若还找
      不到， reslog 就无法执行。
      你可以由 CPAN 模组库下载安装 Compress::Bzip2 ：

 ◎安装指南
    若你是由 reslog 3.10 以前的版本升级，或是由 reslog.pl 3.02 以前的
 版本升级，请参阅 UPGRADE.zh-tw 档的升级说明。
 ◎◎以 ExtUtils::MakeMaker 安装
    reslog 用 Perl 标准的 ExtUtils::MakeMaker 安装，程序如下：
    % perl Makefile.PL
    % make
    % make test
    % make install
    在 make install 前，请先确认你有在安装目录存档的权限。通常这时候
 要切换为 root ，才能安装存档。
    若你是用 MS-Windows 下的 ActivePerl ， make 请改用 nmake 。 nmake
 可由微软的 FTP 站下载：
  ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe
    若要安装到其它地方，请设定好 PREFIX 。例如，一般使用者，要安装在
 自己的目录下时：
  % perl Makefile.PL PREFIX=/home/jessica
    要知道更多安装选项的细节，请参阅 ExtUtils::MakeMaker 的说明（请执
 行 perldoc ExtUtils::MakeMaker ）。
 ◎◎以 Module::Build 安装
    若你喜欢，也可以用 Module::Build 安装，程序如下：
    % perl Build.PL
    % ./Build
    % ./Build test
    % ./Build install
    在 ./Build install 前，请先确认你有在安装目录存档的权限。通常这时
 候要切换为 root ，才能安装存档。
    若要安装到其它地方，请设定好 --prefix 。例如，一般使用者，要安装
 在自己的目录下时：
  % perl Build.PL --prefix=/home/jessica
    要知道更多安装选项的细节，请参阅 Module::Build 的说明（请执行
 perldoc Module::Build ）。

 reslog 安裝指南
 ◎目錄
  ◎系統需求
  ◎安裝指南
    ◎◎以 ExtUtils::MakeMaker 安裝
    ◎◎以 Module::Build 安裝
 ◎系統需求
   1. Perl 5.8.0 或以上。 reslog 使用三參數的 open() 以複製檔案操作，
 我還不知道怎麼改寫到更早的版本上執行。若妳可以改寫到更早的版本上執行，
 請告訴我。妳可以輸入 perl -v 查詢妳目前的 Perl 版本。目前大多數的 Unix
 系統都有 Perl 。如果妳沒有 Perl 或需要昇級，可以到 Perl 網站下載安裝最
 新版 Perl 。
  http://www.perl.com/
      若妳用 MS-Windows ，可以下載安裝 ActiveState 公司的 ActivePerl 。
  http://www.activestate.com/
   2. 需搭配的 Perl 模組：無。
   3. 選配的 Perl 模組：
     * File::MMagic
          這是檢查檔案類型用的。若沒有安裝， reslog 會試著去找 file 程
      式代替。若還找不到， reslog 會改用檔尾（副檔名）判斷檔案類型。這
      時若從標準輸入讀檔， reslog 會無法判斷。
      妳可以由 CPAN 模組庫下載安裝 File::MMagic ：
      http://search.cpan.org/dist/File-MMagic/ ，
      或用 CPAN Shell 執行 cpan File::MMagic 安裝，
      或用 CPANPLUS Shell 執行 cpanp i File::MMagic 安裝。
      若妳是 Debian/Ubandu Linux 使用者，可以執行
      apt-get install libfile-mmagic-perl 安裝。
      若妳是 Red Hat/Fedora/CentOS Linux 使用者，可以執行
      yum install perl-File-MMagic 安裝。
      若妳是 FreeBSD 使用者，可以執行
      ports install p5-File-MMagic 安裝。
      若妳是 ActivePerl 使用者，可以執行
      ppm install File::MMagic 安裝。
      若妳要在 MS-Windows 下使用 file.exe 程式，可以由
      GnuWin32 網站下載： http://gnuwin32.sourceforge.net/ 。
      請確認下載後，存檔在系統的路徑下，檔名為 file.exe 。
          建議用 File::MMagic 。 file 程式偶爾會誤判。
     * Compress::Zlib
          這是處理 gzip 壓縮檔用的，只有處理 gzip 壓縮檔時才會用到。若
      要用時沒有安裝， reslog 會試著改用 gzip 程式代替。若還找不到，
      reslog 就無法執行。
      妳可以由 CPAN 模組庫下載安裝 Compress::Zlib ：
      http://search.cpan.org/dist/Compress-Zlib/ ，
      或用 CPAN Shell 執行 cpan Compress::Zlib 安裝，
      或用 CPANPLUS Shell 執行 cpanp i Compress::Zlib 安裝。
      若妳是 Debian/Ubandu Linux 使用者，可以執行
      apt-get install libcompress-zlib-perl 安裝。
      若妳是 Red Hat/Fedora/CentOS Linux 使用者，可以執行
      yum install perl-Compress-Zlib 安裝。
      若妳是 FreeBSD 使用者，可以執行
      ports install p5-Compress-Zlib 安裝。
      若妳是 ActivePerl 使用者，可以執行
      ppm install Compress::Zlib 安裝。
      若妳要在 MS-Windows 下使用 gzip.exe 程式，可以由
      gzip 網站下載： http://www.gzip.org/ 。
      請確認下載後，存檔在系統的路徑下，檔名為 gzip.exe 。
     * Compress::Bzip2 第二版以上
          這是支援讀寫 bzip2 壓縮檔用的，只有處理 bzip2 壓縮檔時才會用
      到。若要用時沒有安裝， reslog 會試著改用 bzip2 程式代替。若還找
      不到， reslog 就無法執行。
      妳可以由 CPAN 模組庫下載安裝 Compress::Bzip2 ：
      http://search.cpan.org/dist/Compress-Bzip2/ ，
      或用 CPAN Shell 執行 cpan Compress::Bzip2 安裝，
      或用 CPANPLUS Shell 執行 cpanp i Compress::Bzip2 安裝。
      若妳是 Debian/Ubandu Linux 使用者，可以執行
      apt-get install libcompress-bzip2-perl 安裝。
      若妳是 Red Hat/Fedora/CentOS Linux 使用者，可以執行
      yum install perl-Compress-Bzip2 安裝。
      若妳是 FreeBSD 使用者，可以執行
      ports install p5-Compress-Bzip2 安裝。
      若妳是 ActivePerl 使用者，可以執行
      ppm install Compress::Bzip2 安裝。
      若妳要在 MS-Windows 下使用 bzip2.exe 程式，可以由
      bzip2 網站下載： http://www.bzip.org/ 。
      請確認下載後，存檔在系統的路徑下，檔名為 bzip2.exe 。
     * Term::ReadKey
          這是顯示進度列用的，若沒有安裝，就不會顯示進度列。此外不會有
      任何問題。進度列可以讓妳對 reslog 的工作進度一目瞭然。
      妳可以由 CPAN 模組庫下載安裝 Term::ReadKey ：
      http://search.cpan.org/dist/TermReadKey/ ，
      或用 CPAN Shell 執行 cpan Term::ReadKey 安裝，
      或用 CPANPLUS Shell 執行 cpanp i Term::ReadKey 安裝。
      若妳是 Debian/Ubandu Linux 使用者，可以執行
      apt-get install libterm-readkey-perl 安裝。
      若妳是 Red Hat/Fedora/CentOS Linux 使用者，可以執行
      yum install perl-TermReadKey 安裝。
      若妳是 FreeBSD 使用者，可以執行
      ports install p5-Term-ReadKey 安裝。
      若妳是 ActivePerl 使用者，可以執行
      ppm install Term::ReadKey 安裝。
 ◎安裝指南
    若妳是由 reslog 3.10 以前的版本昇級，或是由 reslog.pl 3.02 以前的
 版本昇級，請參閱 UPGRADE.zh-tw 檔的昇級說明。
 ◎◎以 ExtUtils::MakeMaker 安裝
    reslog 用 Perl 標準的 ExtUtils::MakeMaker 安裝，程序如下：
    % perl Makefile.PL
    % make
    % make test
    % make install
    在 make install 前，請先確認妳有在安裝目錄存檔的權限。通常這時候
 要切換為 root ，才能安裝存檔。
    若妳是用 MS-Windows 下的 ActivePerl ， make 請改用 nmake 。 nmake
 可由微軟的 FTP 站下載：
  ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe
    若要安裝到其它地方，請設定好 PREFIX 。例如，一般使用者，要安裝在
 自己的目錄下時：
  % perl Makefile.PL PREFIX=/home/jessica
    要知道更多安裝選項的細節，請參閱 ExtUtils::MakeMaker 的說明（請執
 行 perldoc ExtUtils::MakeMaker ）。
 ◎◎以 Module::Build 安裝
    若妳喜歡，也可以用 Module::Build 安裝，程序如下：
    % perl Build.PL
    % ./Build
    % ./Build test
    % ./Build install
    在 ./Build install 前，請先確認妳有在安裝目錄存檔的權限。通常這時

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

 `reslog` - Reverse-resolve IP in Apache log files
 ===============================================
 Description
 -----------
 `reslog` reverse-resolves IP in the [Apache] log files.  These log
 files can then be analyzed by another program, like [Analog].  You can
 think of it as a replacement of Apache `HostNameLookups` directive, in
 the sense that it batch resolves the client IP once a day.
 [Apache]: https://httpd.apache.org
 [Analog]: https://www.c-amie.co.uk/software/analog
 Caution
 -------
 * *Resolving takes long time*.  This is mainly caused by the look up:
  Network packets may be filtered by firewalls; DNS servers may not be
  correctly configured; may not be up working; may sit in slow network
  sections; may be old slow machines; may have traffic jam… etc.  All
  these problems are beyond our control.
 * If it stops in the middle of its execution, as when the user hits a
  `Ctrl-Break`, it may leave a temporary working file.  The next time
  it runs, it stops when it sees that temporary working file at the
  first sight.  Please process that file first.  You can resolve it
  again, just like an ordinary log file.
 * `reslog` needs temporary working space.  Disk space is cheaper and
  is more available than memory.  However, this means that it needs
  free temporary disk space about 2 times of the size of the
  uncompressed source log file (10 times if using memory).  Please
  make sure you have that much free space.
 * `reslog` does not support IPv6 yet.
 * I suggest that you install [File::MMagic] instead of counting on the
  `file` executable.  The internal magic file of File::MMagic works
  better than the `file` executable.  `reslog` treats everything not
  gzip nor bzip2 compressed as plain text.  When a compressed log file
  is wrongly recognized as an image, `reslog` treats it as plain text,
  reads directly from it, and fails.  This does not hurt the source
  log files, but is still annoying.
 [File::MMagic]: https://metacpan.org/release/File-MMagic
 System Requirement
 ------------------
 1. Perl, version 5.8.0 or above.  `reslog` uses 3-argument open() to
   duplicate file handles, which is only supported since 5.8.0.  I
   have not successfully port this onto earlier versions yet.  Please
   tell me if you made it.  You can run `perl -v` to see your current
   Perl version.  If you do not have Perl, or if you have an older
   version of Perl, you can download and install/upgrade it from the
   [Perl website].  If you are using MS-Windows, you can download and
   install [ActiveState ActivePerl].
 2. Required Perl modules: None.
 3. Optional Perl modules:
   * [File::MMagic]
     This is used to check the file type.  If this is not available,
     `reslog` tries the `file` executable instead.  If that is not
     available, too, `reslog` judges the file type by its name suffix
     (extension).  In that case `reslog` fails when reading from
     `STDIN`.  You can download and install File::MMagic from the CPAN
     archive, or install it with the CPAN shell:
         cpan File::MMagic
     or with the CPANPLUS shell:
         cpanp i File::MMagic
     For Debian/Ubuntu:
         sudo apt install libfile-mmagic-perl
     For Red Hat/Fedora/CentOS:
         sudo yum install perl-File-MMagic
     For FreeBSD:
         ports install p5-File-MMagic
     For ActivePerl:
         ppm install File-MMagic
     The alternative `file.exe` for MS-Windows can be obtained from
     the [GnuWin32] home page.  Be sure to save it as `file.exe`
     somewhere in your `PATH`.
   * [Compress::Zlib]
     This is used to support reading/writing the gzip compressed
     files.  It is only needed when gzip compressed files are
     encountered.  If it is not available, `reslog` tries the `gzip`
     executable instead.  If that is not available, too, `reslog`
     fails.  You can download and install Compress::Zlib from the CPAN
     archive, or install it with the CPAN shell:
         cpan Compress::Zlib
     or with the CPANPLUS shell:
         cpanp i Compress::Zlib
     For Debian/Ubuntu:
         sudo apt install libcompress-zlib-perl
     For Red Hat/Fedora/CentOS:
         sudo yum install perl-Compress-Zlib
     For FreeBSD:
         ports install p5-Compress-Zlib
     For ActivePerl:
         ppm install Compress-Zlib
     The alternative `gzip.exe` for MS-Windows can be obtained from
     [the gzip website].  Be sure to save it as `gzip.exe` somewhere
     in your `PATH`.
   * [Compress::Bzip2] version 2 or above.
     This is used to support reading/writing the bzip2 compressed
     files.  It is only needed when bzip2 compressed files are
     encountered.  If it is not available, `reslog` tries the `bzip2`
     executable instead.  If that is not available, too, `reslog`
     fails.  Notice that older versions before 2 does not work, since
     the file I/O compression was not implemented yet.  You can
     download and install Compress::Bzip2 from the CPAN archive, or
     install it with the CPAN shell:
         cpan Compress::Bzip2
     or with the CPANPLUS shell:
         cpanp i Compress::Bzip2
     For Debian/Ubuntu:
         sudo apt install libcompress-bzip2-perl
     For Red Hat/Fedora/CentOS:
         sudo yum install perl-Compress-Bzip2
     For FreeBSD:
         ports install p5-Compress-Bzip2
     For ActivePerl:
         ppm install Compress-Bzip2
     The alternative `bzip2.exe` for MS-Windows can be obtained from
     [the bzip2 website].  Be sure to save it as `bzip2.exe` somewhere
     in your `PATH`.
   * [Term::ReadKey]
     This is used to display the progress bar.  The progress bar is a
     good visual feedback of what `reslog` is currently doing, but
     `reslog` is safe without it.  You can download and install
     Term::ReadKey from the CPAN archive, or install it with the
     CPAN shell:
         cpan Term::ReadKey
     or with the CPANPLUS shell:
         cpanp i Term::ReadKey
     For Debian/Ubuntu:
         sudo apt install libterm-readkey-perl
     For Red Hat/Fedora/CentOS:
         sudo yum install perl-TermReadKey
     For FreeBSD:
         ports install p5-Term-ReadKey
     For ActivePerl:

 Install
 -------
 If you are upgrading from `reslog` 3.10 or earlier, or if you are
 upgrading from `reslog.pl` 3.02 or earlier, please read the upgrade
 instruction later in this document.
 ### Install with [ExtUtils::MakeMaker]
 `reslog` uses standard Perl installation with ExtUtils::MakeMaker.
 Follow these steps:
    % perl Makefile.PL
    % make
    % make test
    % make install
 When running `make install`, make sure you have the privilege to
 write to the installation location.  This usually requires the `root`
 privilege.
 If you are using ActivePerl under MS-Windows, you should use `nmake`
 instead of `make`.  [nmake can be obtained from the Microsoft FTP site.]
 If you want to install into another location, you can set the
 `PREFIX`.  For example, to install into your home when you are not
 `root`:
    % perl Makefile.PL PREFIX=/home/jessica
 Refer to the documentation of ExtUtils::MakeMaker for more
 installation options (by running `perldoc ExtUtils::MakeMaker`).
 ### Install with [Module::Build]
 You can install with Module::Build instead, if you prefer.  Follow
 these steps:
    % perl Build.PL
    % ./Build
    % ./Build test
    % ./Build install
 When running `./Build install`, make sure you have the privilege to
 write to the installation location.  This usually requires the `root`
 privilege.
 If you want to install into another location, you can set the
 `--prefix`.  For example, to install into your home when you are not
 `root`:
    % perl Build.PL --prefix=/home/jessica
 Refer to the documentation of Module::Build for more installation
 options (by running `perldoc Module::Build`).
 [ExtUtils::MakeMaker]: https://metacpan.org/release/ExtUtils-MakeMaker
 [nmake can be obtained from the Microsoft FTP site.]: ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe
 [Module::Build]: https://metacpan.org/release/Module-Build
 Upgrade Instruction
 -------------------
 Here are a few hints for people upgrading from 3.10 or earlier:
 ### The Default Installation Location Is at `/usr/bin`
 Also, the man page is at `/usr/share/man/man1/reslog.1`.  This is to
 follow Perl’s standard convention, and to avoid breaking
 ExtUtils::MakeMaker with future versions.
 When you run `perl Makefile.PL` or `perl Build.PL`, it hints a
 list of existing old files to be removed.  Please delete them
 manually.
 If you saved them in other places, you have to delete them yourself.
 Also, if you have any scripts or cron jobs that are running `reslog`,
 remember to modify your script for the new `reslog` location.  Of
 course, you can copy `reslog` to the original location.  It still
 works.
 Here are a few hints for people upgrading from 3.02 or earlier:
 ### The Script Name is Changed from `reslog.pl` to `reslog`
 This is obvious.  If you have any scripts or cron jobs that are
 running `reslog`, remember to modify your script for the new name.
 Of course, you can rename `reslog` to `reslog.pl`.  It still works.
 The reason I changed the script and project name is that:  A dot `.`
 in the project name is not valid everywhere.  At least SourceForge
 don’t accept it.  Besides, `reslog` is enough for a script name under
 UNIX.  The `.pl` file name suffix/extension may be convenient on
 MS-Windows, but MS-Windows users won’t run it with explorer file name
 association anyway, and there is a `pl2bat` to convert `reslog` to
 `reslog.bat`, which would make more sense.  The only disadvantage is
 that I was using `UltraEdit`, which depends on the file name extension
 for the syntax highlighting rules.  I can manually set it anyway.  I’m
 using `gedit` on Linux now.  This is not a problem anymore.
 ### You Need Perl 5.8.0 or Above
 `reslog` now has threading to speed up resolving, which requires
 Perl’s `ithreads` threading module support that’s only available since
 5.8.0.  You can still disable threading if it causes troubles to you,
 but the code itself need it.  If you are using a Perl before 5.8.0,
 please upgrade it.  You can run `perl -v` to see your current Perl
 version.
 ### The Default Keep Mode is Now `delete`
 The documentation said the default keep mode is `delete`, but `reslog`
 actually did a `restart`. :p  This is fixed.  If you are running with
 the default keep mode, remember to fix it.
 ### The Argument of `--keep` and `--override` Options Are Required Now
 Support for omitting the `--keep` or `--override` arguments are
 removed.  This helps to avoid confusion for the log file name and the
 option arguments.
 ### Specifying One `STDIN` No Longer Trigger Everything to `STDOUT`
 When resolving multiple files, `STDIN` can output to `STDOUT` now,
 with other files output to where they should be.  Specifying one
 `STDIN` no longer writes everything to `STDOUT`.  If you want to write
 everything to `STDOUT`, be sure to add the `--stdout` option.
 Options
 -------
    ./reslog [options] [logfile…]
    ./reslog [-h|-v]
 * `logfile`
  The log file to be resolved.  You can specify multiple log files.
  If not specified, it reads from `STDIN` and outputs to `STDOUT`.
  You can also specify `-` to read from `STDIN`.  Result of `STDIN`
  goes to `STDOUT`.  `gzip` or `bzip2` compressed files are supported.
 * `-k`, `--keep mode`
  What to keep in the source file.  The following modes are supported:
  * `a`, `all`
    Keep the source file after records are archived.
  * `r`, `restart`
    Restart the source file after records are resolved.
  * `d`, `delete`
    Delete the source file after records are resolved.  This is the
    default.
 * `-o`, `--override mode`
  What to do with the existing resolved files.  The following modes
  are supported:
  * `o`, `overwrite`
    Overwrite existing target files.
  * `a`, `append`
    Append the records to existing target files.
  * `f`, `fail`
    Stop processing whenever a target file exists, to prevent
    destroying existing files by accident.  This is the default.
 * `-s`, `--suffix suf`
  The suffix to be appended to the output file.  If not specified,
  the default is `.resolved`.
 * `-t`, `--trim-suffix suf`
  The suffix to be trimmed from the input file name before appending
  the above suffix.  Default is none.  If you are running several log
  file filters, this can help you trim the suffix of the previous one.
 * `-n`, `--num-threads num`
  Number of threads to run simultaneously.  The default is 10.  Use 0
  to disable threading.  Your system must support threading itself.
  This option has no effect for systems that do not support threading.
 * `-c`, `--stdout`
  Output the result to `STDOUT`.
 * `-d`, `--debug`
  Show the detailed debugging messages.  More `-d` to be more
  detailed.
 * `-q`, `--quiet`
  Hush!  Only yell on error.
 * `-h`, `--help`
  Display the help message and exit.
 * `-v`, `--version`
  Output version information and exit.

 Upgrade Instruction
    Here are a few hints for people upgrading from 3.10 or earlier:
 * The Default Installation Location Is at /usr/bin
    Also, the man page is at /usr/share/man/man1/reslog.1.  This is to follow
 Perl's standard convension, and to avoid breaking ExtUtils::MakeMaker with
 future versions.
    When you run "perl Makefile.PL" or "perl Build.PL", it will hint a list of
 old files found to be removed.  Please delete them manually.
    If you saved them in other places, you have to delete them yourself.
    Also, if you have any scripts or cron jobs that are running reslog, remember
 to modify your script for the new reslog location.  Of course, you can copy
 reslog to the original location.  It will still work.
    Here are a few hints for people upgrading from 3.02 or earlier:
 * The Script Name is Changed from reslog.pl to reslog
    This is obvious.  If you have any scripts or cron jobs that are running
 reslog, remember to modify your script for the new name.  Of course, you can
 rename reslog to reslog.pl.  It will still work.
    The reason I changed the script and project name is that:  A dot "." in
 the project name is not valid everywhere.  At least SourceForge don't accept
 it.  Besides, "reslog" is enough for a script name under UNIX.  The ".pl" file
 name suffix/extension may be convienent for MS-Windows, but MS-Windows users
 won't run it with explorer file name association anyway, and there is a pl2bat
 to convert "reslog" to "reslog.bat", which would make more sense.  The only
 disadvantage is that I use UltraEdit, which depends on the file name extension
 for the automatic syntax highlighting rules.  But this is not much trouble.  I
 can manuall set it anyway.
 * You Need Perl 5.8.0 or Above
    reslog now has threading to speed up resolving, which requires Perl's
 ithreads threading module support that's only available since 5.8.0.  You can
 still disable threading if it causes troubles to you, but the code itself need
 it.  If you are using a Perl before 5.8.0, please upgrade it.  You can run
 "perl -v" to see your current Perl version.
 * The Default Keep Mode is Now "delete"
    The documentation said the default keep mode is "delete", but the script
 actually did a "restart". :p  This is fixed.  If you are running with the
 default keep mode, remember to fix it.
 * The Argument of --keep and --override Options Are Required Now
    Support for omitting --keep or --override argument is removed.  This helps
 avoiding confusion for the log file name and the option arguments.
 * Specifying STDIN Will No Longer Trigger STDOUT
    When resolving multiple files, STDIN can output to STDOUT now, with other
 files output to where they should be.  Specifying an STDIN will no longer
 automatically trigger outputing everything to STDOUT.  If you want to output
 everything to STDOUT, be sure to add the --stdout option.

 升级指南
 　　若你由 3.10 或之前的版本升级，请阅读以下说明：
 ◎预设安装目录为 /usr/bin
 　　说明档则在 /usr/share/man/man1/reslog.1 。这是为符合 Perl 的标准安装流程，
 敝免破坏 ExtUtils::MakeMaker 的预设设定，造成日后升级的问题。
 　　执行 perl Makefile.PL 或 perl Build.PL 时，会提示你所在系统上发现的的旧档
 案。请自行删除。若你程式存在其它地方，请记得要自己删掉。
 　　若你有写程式，或设定 cron 排程来执行 reslog ，请记得更改档名。不过你也可以
 把 reslog 存到原来的目录去，不会有任何问题。
 　　若你由 3.02 或之前的版本升级，请阅读以下说明：
 ◎档名由 reslog.pl 改为 reslog
 　　这很明显吧。 :p 若你有写程式，或设定 cron 排程来执行 reslog ，请记得更改档
 名。不过你也可以把 reslog 改名回原来的 reslog.pl ，不会有任何问题。
 　　改名原因如下：专案名称含「.」会处处碰壁。 SourceForget 就不接受含「.」的专
 案名称。此外，程式名称 reslog 在 UNIX 下就可以跑了。副档名 .pl 虽然在
 MS-Windows 下方便，但反正 MS-Windows 下也不会直接点两下依副档名执行。而且还有
 pl2bat 可以把 reslog 转成 reslog.bat ，这样反而比较合理。唯一不便的是我用的编
 辑器 UltraEdit 依副档名决定程式语言语法标示，不过这也没什么大不了，手动设程式
 语言就好了。
 ◎ Perl 5.8.0 版以上
 　　新版的 reslog 用多线程加速反查，要用到 Perl 5.8.0 之后的新 ithread 多线程
 模式。你若不想用多线程功能，可以不用，不过程式码本身，还是要用到 ithread 。若
 你用的是 5.8.0 以前的 Perl 版本，请升级你的 Perl 。你可以输入 perl -v 查询你目
 前的 Perl 版本。
 ◎预设 keep 原记录档保留模式是 delete
 　　我在说明文件上写，预设 keep 原记录档保留模式是 delete 删除，可是其实程式真
 正跑的是 restart 归零。 :p 这个问题已经修好了。如果你依预设保留模式执行，请记
 得要修正。
 ◎ --keep 和 --override 选项现在一定要加模式参数
 　　以前可以直接用 --keep 和 --override 选项，不加参数，现在一定要加参数，以避
 免混淆选项的参数和要处理的记录档名。
 ◎读取标准输入 STDIN 不会自动启动标准输出 STDOUT 模式
 　　一次读取多个档案时，只有标准输入 STDIN 的结果会输出到标准输出，其它档案都
 会输出到各自该输出的档案去。以前一次读取多档时，或其中有一个是标准输入，则会全
 部输出到标准输出去，现在不会了。若你需要把全部的结果输出到标准输出，请加上
 --stdout 选项。

 		GNU Free Documentation License
 		  Version 1.2, November 2002
 Copyright (C) 2000,2001,2002  Free Software Foundation, Inc.
     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 0. PREAMBLE
 The purpose of this License is to make a manual, textbook, or other
 functional and useful document "free" in the sense of freedom: to
 assure everyone the effective freedom to copy and redistribute it,
 with or without modifying it, either commercially or noncommercially.
 Secondarily, this License preserves for the author and publisher a way
 to get credit for their work, while not being considered responsible
 for modifications made by others.
 This License is a kind of "copyleft", which means that derivative
 works of the document must themselves be free in the same sense.  It
 complements the GNU General Public License, which is a copyleft
 license designed for free software.
 We have designed this License in order to use it for manuals for free
 software, because free software needs free documentation: a free
 program should come with manuals providing the same freedoms that the
 software does.  But this License is not limited to software manuals;
 it can be used for any textual work, regardless of subject matter or
 whether it is published as a printed book.  We recommend this License
 principally for works whose purpose is instruction or reference.
 1. APPLICABILITY AND DEFINITIONS
 This License applies to any manual or other work, in any medium, that
 contains a notice placed by the copyright holder saying it can be
 distributed under the terms of this License.  Such a notice grants a
 world-wide, royalty-free license, unlimited in duration, to use that
 work under the conditions stated herein.  The "Document", below,
 refers to any such manual or work.  Any member of the public is a
 licensee, and is addressed as "you".  You accept the license if you
 copy, modify or distribute the work in a way requiring permission
 under copyright law.
 A "Modified Version" of the Document means any work containing the
 Document or a portion of it, either copied verbatim, or with
 modifications and/or translated into another language.
 A "Secondary Section" is a named appendix or a front-matter section of
 the Document that deals exclusively with the relationship of the
 publishers or authors of the Document to the Document's overall subject
 (or to related matters) and contains nothing that could fall directly
 within that overall subject.  (Thus, if the Document is in part a
 textbook of mathematics, a Secondary Section may not explain any
 mathematics.)  The relationship could be a matter of historical
 connection with the subject or with related matters, or of legal,
 commercial, philosophical, ethical or political position regarding
 them.
 The "Invariant Sections" are certain Secondary Sections whose titles
 are designated, as being those of Invariant Sections, in the notice
 that says that the Document is released under this License.  If a
 section does not fit the above definition of Secondary then it is not
 allowed to be designated as Invariant.  The Document may contain zero
 Invariant Sections.  If the Document does not identify any Invariant
 Sections then there are none.
 The "Cover Texts" are certain short passages of text that are listed,
 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
 the Document is released under this License.  A Front-Cover Text may
 be at most 5 words, and a Back-Cover Text may be at most 25 words.
 A "Transparent" copy of the Document means a machine-readable copy,
 represented in a format whose specification is available to the
 general public, that is suitable for revising the document
 straightforwardly with generic text editors or (for images composed of
 pixels) generic paint programs or (for drawings) some widely available
 drawing editor, and that is suitable for input to text formatters or
 for automatic translation to a variety of formats suitable for input
 to text formatters.  A copy made in an otherwise Transparent file
 format whose markup, or absence of markup, has been arranged to thwart
 or discourage subsequent modification by readers is not Transparent.
 An image format is not Transparent if used for any substantial amount
 of text.  A copy that is not "Transparent" is called "Opaque".
 Examples of suitable formats for Transparent copies include plain
 ASCII without markup, Texinfo input format, LaTeX input format, SGML
 or XML using a publicly available DTD, and standard-conforming simple
 HTML, PostScript or PDF designed for human modification.  Examples of
 transparent image formats include PNG, XCF and JPG.  Opaque formats
 include proprietary formats that can be read and edited only by
 proprietary word processors, SGML or XML for which the DTD and/or
 processing tools are not generally available, and the
 machine-generated HTML, PostScript or PDF produced by some word
 processors for output purposes only.
 The "Title Page" means, for a printed book, the title page itself,
 plus such following pages as are needed to hold, legibly, the material
 this License requires to appear in the title page.  For works in
 formats which do not have any title page as such, "Title Page" means
 the text near the most prominent appearance of the work's title,
 preceding the beginning of the body of the text.
 A section "Entitled XYZ" means a named subunit of the Document whose
 title either is precisely XYZ or contains XYZ in parentheses following
 text that translates XYZ in another language.  (Here XYZ stands for a
 specific section name mentioned below, such as "Acknowledgements",
 "Dedications", "Endorsements", or "History".)  To "Preserve the Title"
 of such a section when you modify the Document means that it remains a
 section "Entitled XYZ" according to this definition.
 The Document may include Warranty Disclaimers next to the notice which
 states that this License applies to the Document.  These Warranty
 Disclaimers are considered to be included by reference in this
 License, but only as regards disclaiming warranties: any other
 implication that these Warranty Disclaimers may have is void and has
 no effect on the meaning of this License.
 2. VERBATIM COPYING
 You may copy and distribute the Document in any medium, either
 commercially or noncommercially, provided that this License, the
 copyright notices, and the license notice saying this License applies
 to the Document are reproduced in all copies, and that you add no other
 conditions whatsoever to those of this License.  You may not use
 technical measures to obstruct or control the reading or further
 copying of the copies you make or distribute.  However, you may accept
 compensation in exchange for copies.  If you distribute a large enough
 number of copies you must also follow the conditions in section 3.
 You may also lend copies, under the same conditions stated above, and
 you may publicly display copies.
 3. COPYING IN QUANTITY
 If you publish printed copies (or copies in media that commonly have
 printed covers) of the Document, numbering more than 100, and the
 Document's license notice requires Cover Texts, you must enclose the
 copies in covers that carry, clearly and legibly, all these Cover
 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
 the back cover.  Both covers must also clearly and legibly identify
 you as the publisher of these copies.  The front cover must present
 the full title with all words of the title equally prominent and
 visible.  You may add other material on the covers in addition.
 Copying with changes limited to the covers, as long as they preserve
 the title of the Document and satisfy these conditions, can be treated
 as verbatim copying in other respects.
 If the required texts for either cover are too voluminous to fit
 legibly, you should put the first ones listed (as many as fit
 reasonably) on the actual cover, and continue the rest onto adjacent
 pages.
 If you publish or distribute Opaque copies of the Document numbering
 more than 100, you must either include a machine-readable Transparent
 copy along with each Opaque copy, or state in or with each Opaque copy
 a computer-network location from which the general network-using
 public has access to download using public-standard network protocols
 a complete Transparent copy of the Document, free of added material.
 If you use the latter option, you must take reasonably prudent steps,
 when you begin distribution of Opaque copies in quantity, to ensure
 that this Transparent copy will remain thus accessible at the stated
 location until at least one year after the last time you distribute an
 Opaque copy (directly or through your agents or retailers) of that
 edition to the public.
 It is requested, but not required, that you contact the authors of the
 Document well before redistributing any large number of copies, to give
 them a chance to provide you with an updated version of the Document.
 4. MODIFICATIONS
 You may copy and distribute a Modified Version of the Document under
 the conditions of sections 2 and 3 above, provided that you release
 the Modified Version under precisely this License, with the Modified
 Version filling the role of the Document, thus licensing distribution
 and modification of the Modified Version to whoever possesses a copy
 of it.  In addition, you must do these things in the Modified Version:
 A. Use in the Title Page (and on the covers, if any) a title distinct
   from that of the Document, and from those of previous versions
   (which should, if there were any, be listed in the History section
   of the Document).  You may use the same title as a previous version
   if the original publisher of that version gives permission.
 B. List on the Title Page, as authors, one or more persons or entities
   responsible for authorship of the modifications in the Modified
   Version, together with at least five of the principal authors of the
   Document (all of its principal authors, if it has fewer than five),
   unless they release you from this requirement.
 C. State on the Title page the name of the publisher of the
   Modified Version, as the publisher.
 D. Preserve all the copyright notices of the Document.
 E. Add an appropriate copyright notice for your modifications
   adjacent to the other copyright notices.
 F. Include, immediately after the copyright notices, a license notice
   giving the public permission to use the Modified Version under the
   terms of this License, in the form shown in the Addendum below.
 G. Preserve in that license notice the full lists of Invariant Sections
   and required Cover Texts given in the Document's license notice.
 H. Include an unaltered copy of this License.
 I. Preserve the section Entitled "History", Preserve its Title, and add
   to it an item stating at least the title, year, new authors, and
   publisher of the Modified Version as given on the Title Page.  If
   there is no section Entitled "History" in the Document, create one
   stating the title, year, authors, and publisher of the Document as
   given on its Title Page, then add an item describing the Modified
   Version as stated in the previous sentence.
 J. Preserve the network location, if any, given in the Document for
   public access to a Transparent copy of the Document, and likewise
   the network locations given in the Document for previous versions
   it was based on.  These may be placed in the "History" section.
   You may omit a network location for a work that was published at
   least four years before the Document itself, or if the original
   publisher of the version it refers to gives permission.
 K. For any section Entitled "Acknowledgements" or "Dedications",
   Preserve the Title of the section, and preserve in the section all
   the substance and tone of each of the contributor acknowledgements
   and/or dedications given therein.
 L. Preserve all the Invariant Sections of the Document,
   unaltered in their text and in their titles.  Section numbers
   or the equivalent are not considered part of the section titles.
 M. Delete any section Entitled "Endorsements".  Such a section
   may not be included in the Modified Version.
 N. Do not retitle any existing section to be Entitled "Endorsements"
   or to conflict in title with any Invariant Section.
 O. Preserve any Warranty Disclaimers.
 If the Modified Version includes new front-matter sections or
 appendices that qualify as Secondary Sections and contain no material
 copied from the Document, you may at your option designate some or all
 of these sections as invariant.  To do this, add their titles to the
 list of Invariant Sections in the Modified Version's license notice.
 These titles must be distinct from any other section titles.
 You may add a section Entitled "Endorsements", provided it contains
 nothing but endorsements of your Modified Version by various
 parties--for example, statements of peer review or that the text has
 been approved by an organization as the authoritative definition of a
 standard.
 You may add a passage of up to five words as a Front-Cover Text, and a
 passage of up to 25 words as a Back-Cover Text, to the end of the list
 of Cover Texts in the Modified Version.  Only one passage of
 Front-Cover Text and one of Back-Cover Text may be added by (or
 through arrangements made by) any one entity.  If the Document already
 includes a cover text for the same cover, previously added by you or
 by arrangement made by the same entity you are acting on behalf of,
 you may not add another; but you may replace the old one, on explicit
 permission from the previous publisher that added the old one.
 The author(s) and publisher(s) of the Document do not by this License
 give permission to use their names for publicity for or to assert or
 imply endorsement of any Modified Version.
 5. COMBINING DOCUMENTS
 You may combine the Document with other documents released under this
 License, under the terms defined in section 4 above for modified
 versions, provided that you include in the combination all of the
 Invariant Sections of all of the original documents, unmodified, and
 list them all as Invariant Sections of your combined work in its
 license notice, and that you preserve all their Warranty Disclaimers.
 The combined work need only contain one copy of this License, and
 multiple identical Invariant Sections may be replaced with a single
 copy.  If there are multiple Invariant Sections with the same name but
 different contents, make the title of each such section unique by
 adding at the end of it, in parentheses, the name of the original
 author or publisher of that section if known, or else a unique number.
 Make the same adjustment to the section titles in the list of
 Invariant Sections in the license notice of the combined work.
 In the combination, you must combine any sections Entitled "History"
 in the various original documents, forming one section Entitled
 "History"; likewise combine any sections Entitled "Acknowledgements",
 and any sections Entitled "Dedications".  You must delete all sections
 Entitled "Endorsements".
 6. COLLECTIONS OF DOCUMENTS
 You may make a collection consisting of the Document and other documents
 released under this License, and replace the individual copies of this
 License in the various documents with a single copy that is included in
 the collection, provided that you follow the rules of this License for
 verbatim copying of each of the documents in all other respects.
 You may extract a single document from such a collection, and distribute
 it individually under this License, provided you insert a copy of this
 License into the extracted document, and follow this License in all
 other respects regarding verbatim copying of that document.
 7. AGGREGATION WITH INDEPENDENT WORKS
 A compilation of the Document or its derivatives with other separate
 and independent documents or works, in or on a volume of a storage or
 distribution medium, is called an "aggregate" if the copyright
 resulting from the compilation is not used to limit the legal rights
 of the compilation's users beyond what the individual works permit.
 When the Document is included in an aggregate, this License does not
 apply to the other works in the aggregate which are not themselves
 derivative works of the Document.
 If the Cover Text requirement of section 3 is applicable to these
 copies of the Document, then if the Document is less than one half of
 the entire aggregate, the Document's Cover Texts may be placed on
 covers that bracket the Document within the aggregate, or the
 electronic equivalent of covers if the Document is in electronic form.
 Otherwise they must appear on printed covers that bracket the whole
 aggregate.
 8. TRANSLATION
 Translation is considered a kind of modification, so you may
 distribute translations of the Document under the terms of section 4.
 Replacing Invariant Sections with translations requires special
 permission from their copyright holders, but you may include
 translations of some or all Invariant Sections in addition to the
 original versions of these Invariant Sections.  You may include a
 translation of this License, and all the license notices in the
 Document, and any Warranty Disclaimers, provided that you also include
 the original English version of this License and the original versions
 of those notices and disclaimers.  In case of a disagreement between
 the translation and the original version of this License or a notice
 or disclaimer, the original version will prevail.

 <h2>Description</h2>
 <p><dfn><samp>reslog</samp></dfn> reverse-resolves <abbr title="internet protocol">IP</abbr> in the <a href="http://httpd.apache.org/">Apache</a> log files.  These log files can then be analyzed by another program, like <a href="http://analog.cx/">Analog</a>.  You can think of it as a replacement of Apache <samp>HostNameLookups</samp> directive, in the sense that it resolves the client <abbr title="internet protocol">IP</abbr> altogether once a day.</p>
 <h2>Caution</h2>
 <ul>
 <li><p><em>Resolving takes long time</em>.  This is mainly caused by resolving:  Network packets may be filtered by firewalls; <abbr title="Domain Name Service">DNS</abbr> servers may not be correctly configured; may not be up working; may sit in slow network sections; may be old slow machines; may have traffic jam&hellip; <abbr title="et cetera">etc</abbr>.  All these reasons are out of our control.</p></li>
 <li><p>If it stops in the middle of its execution, as when the user hits a <samp>Ctrl-Break</samp>, it may leave a temporary working file. The next time it runs, it will stop when it sees that temporary working file at the first sight.  Please process that file first.  You can resolve it again, just like an ordinary log file.</p></li>
 <li><p>This prorgam needs temporary working space.  Between memory and disk space, I choose disk space, since it is cheaper and may be available in more environments.  However, this means that it needs free temporary disk space about 2 times of the size of the uncompressed source log log file (10 times if using memory).  Please make sure you have that much free space.</p></li>
 <li><p><samp>reslog</samp> does not support <abbr title="internet protocol version 6">IPv6</abbr> yet.</p></li>
 <li><p>I suggest you to install <a href="http://search.cpan.org/dist/File-MMagic/"><samp>File::MMagic</samp></a> instead of counting on the <samp>file</samp> executable.  The internal magic file of <a href="http://search.cpan.org/dist/File-MMagic/"><samp>File::MMagic</samp></a> seems to work better than the <samp>file</samp> executable.  <samp>reslog</samp> treats everything not <samp>gzip</samp> nor <samp>bzip2</samp> compressed as plain text.  When a compressed log file is wrongly recognized as an image, <samp>reslog</samp> will treat it as plain text, read log records directly from it and fail.  This failure does not hurt the source log files, but is still annoying.</p></li>
 </ul>
 <h2>System Requirement</h2>
 <ol>
 <li><p><acronym title="Practical Extraction and Reporting Language">Perl</acronym>, version 5.8.0 or above.  <samp>reslog</samp> uses 3-argument <samp>open()</samp> to duplicate filehandles, which is only supported since 5.8.0.  I have not successfully port this onto earlier versions yet.  Please tell me if you made it.  You can run <q><samp>perl -v</samp></q> to see your current <acronym title="Practical Extraction and Reporting Language">Perl</acronym> version.  If you do not have <acronym title="Practical Extraction and Reporting Language">Perl</acronym>, or if you have an older version of <acronym title="Practical Extraction and Reporting Language">Perl</acronym>, you can download and install/upgrade it from <a href="http://www.perl.com/">Perl website</a>.  If you are using <abbr title="Microsoft">MS</abbr>-Windows, you can download and install <a href="http://www.activestate.com/">ActiveState ActivePerl</a>.</p></li>
 <li><p>Required <acronym title="Practical Extraction and Reporting Language">Perl</acronym> modules: None.</p></li>
 <li><p>Optional <acronym title="Practical Extraction and Reporting Language">Perl</acronym> modules:</p>
    <dl>
    <dt><a href="http://search.cpan.org/dist/File-MMagic/"><samp>File::MMagic</samp></a></dt>
    <dd>
    <p>This is used to check the file type.  If this is not available, <samp>reslog</samp> will look for the <samp>file</samp> executable instead.  If that is not available, too, <samp>reslog</samp> will judge the file type by its name suffix (extension).  In that case <samp>reslog</samp> will fail when reading from <samp>STDIN</samp>.

 <p>If you are upgrading from <samp>reslog</samp> 3.10 or earlier, or if you are upgrading from <samp>reslog.pl</samp> 3.02 or earlier, please read <samp>UPGRADE</samp> for some upgrade instruction.</p>
 <h3>Install with <a href="http://search.cpan.org/dist/ExtUtils-MakeMaker/"><samp>ExtUtils::MakeMaker</samp></a></h3>
 <p><samp>reslog</samp> uses standard <acronym title="Practical Extraction and Reporting Language">Perl</acronym> installation with <a href="http://search.cpan.org/dist/ExtUtils-MakeMaker/"><samp>ExtUtils::MakeMaker</samp></a>.  Follow these steps:</p>
 <blockquote><pre>
 % perl Makefile.PL
 % make
 % make test
 % make install
 </pre></blockquote>
 <p>When running <q><samp>make install</samp></q>, make sure you have the priviledge to write to the installation location.  This usually requires the <samp>root</samp> priviledge.</p>
 <p>If you are using ActivePerl under <abbr title="Microsoft">MS</abbr>-Windows, you should use <samp>nmake</samp> instead of <samp>make</samp>.  <a href="ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe" type="application/x-dosexec"><samp>nmake</samp> can be obtained from the Microsoft <abbr title="File Transfer Protocol">FTP</abbr> site.</a></p>
 <p>If you want to install into another location, you can set the <samp>PREFIX</samp>.  For example, to install into your home when you are not <samp>root</samp>:</p>
 <blockquote><pre>
 % perl Makefile.PL PREFIX=/home/jessica
 </pre></blockquote>
 <p>Refer to the docuemntation of <a href="http://search.cpan.org/dist/ExtUtils-MakeMaker/" hreflang="en" xml:lang="en"><samp>ExtUtils::MakeMaker</samp></a> for more installation options (by running <q><samp>perldoc ExtUtils::MakeMaker</samp></q>).</p>
 <h3>Install with <a href="http://search.cpan.org/dist/Module-Build/"><samp>Module::Build</samp></a></h3>
 <p>You can install with <a href="http://search.cpan.org/dist/Module-Build/"><samp>Module::Build</samp></a> instead, if you prefer.  Follow these steps:</p>
 <blockquote><pre>
 % perl Build.PL
 % ./Build
 % ./Build test
 % ./Build install
 </pre></blockquote>
 <p>When running <q><samp>./Build install</samp></q>, make sure you have the priviledge to write to the installation location.  This usually requires the <samp>root</samp> priviledge.</p>
 <p>If you want to install into another location, you can set the <samp>--prefix</samp>.  For example, to install into your home when you are not <samp>root</samp>:</p>

 <h2>说明</h2>
 <p><dfn xml:lang="en"><samp>reslog</samp></dfn> 是记录档的反查程式，用来反查 <a href="http://httpd.apache.org/" hreflang="en" xml:lang="en">Apache</a> 记录档里 <abbr title="internet protocol" xml:lang="en">IP</abbr> 的主机名称。查过后，可以套用像 <a href="http://analog.cx/" hreflang="en" xml:lang="en">Analog</a> 之类的记录档统计程式。你可以把它当做 <span xml:lang="en">Apache</span> <samp xml:lang="en">HostNameLookups</samp> 指令的替代品，每天一次反查当天所有的 <abbr title="internet protocol" xml:lang="en">IP</abbr> 。</p>
 <h2>注意事项</h2>
 <ul>
 <li><p>反查网域名称<em>很耗时间</em>。时间主要耗在查询上：防火墙过滤网路封包，网域名称伺服器设错、没有开机、位在慢速网路上、等级太低反应慢、网路塞车&hellip;等。这些外部因素，都不是程式本身能控制的。</p></li>
 <li><p>若程式半途中断，如按了 <span xml:lang="en">Ctrl-Break</span> ，可能会残余一个暂时工作档。下次执行时碰到残存的暂时工作档，程式会拒绝执行跳出。请先处理残存的暂时工作档。你可以把暂时工作档当成原来的记录档来用，重新反查。</p></li>
 <li><p>本程式需要很多暂存资料的空间。硬碟和记忆体比起来，价格便宜，用起来也比较省，所以我用硬碟暂存。这个程式需要原记录档解压后两倍以上的硬碟空间，才能执行（用记忆体暂存的话要用十倍）。请检查硬碟空间够不够。</p></li>
 <li><p><samp xml:lang="en">reslog</samp> 尚未支援 <abbr title="internet protocol version 6" xml:lang="en">IPv6</abbr> 。</p></li>
 <li><p>我建议安装 <a href="http://search.cpan.org/dist/File-MMagic/" hreflang="en" xml:lang="en"><samp>File::MMagic</samp></a> ，尽量不要用 <samp xml:lang="en">file</samp> 程式。 <a href="http://search.cpan.org/dist/File-MMagic/" hreflang="en" xml:lang="en"><samp>File::MMagic</samp></a> 内建的档案类型表好像比 <samp xml:lang="en">file</samp> 程式准确。若不是 <samp xml:lang="en">gzip</samp> 或 <samp xml:lang="en">bzip2</samp> 压缩档， <samp xml:lang="en">reslog</samp> 会把视为当成纯文字档。若压缩档被误判为图档， <samp xml:lang="en">reslog</samp> 会当成纯文字档，直接读记录，并以错误结束。就算错误也不会弄乱原记录档，不过多少有点麻烦。</p></li>
 </ul>
 <h2>系统需求</h2>

 <h2>說明</h2>
 <p><dfn xml:lang="en"><samp>reslog</samp></dfn> 是記錄檔的反查程式，用來反查 <a href="http://httpd.apache.org/" hreflang="en" xml:lang="en">Apache</a> 記錄檔裏 <abbr title="internet protocol" xml:lang="en">IP</abbr> 的主機名稱。查過後，可以套用像 <a href="http://analog.cx/" hreflang="en" xml:lang="en">Analog</a> 之類的記錄檔統計程式。妳可以把它當做 <span xml:lang="en">Apache</span> <samp xml:lang="en">HostNameLookups</samp> 指令的替代品，每天一次反查當天所有的 <abbr title="internet protocol" xml:lang="en">IP</abbr> 。</p>
 <h2>注意事項</h2>
 <ul>
 <li><p>反查網域名稱<em>很耗時間</em>。時間主要耗在查詢上：防火牆過濾網路封包，網域名稱伺服器設錯、沒有開機、位在慢速網路上、等級太低反應慢、網路塞車&hellip;等。這些外部因素，都不是程式本身能控制的。</p></li>
 <li><p>若程式半途中斷，如按了 <span xml:lang="en">Ctrl-Break</span> ，可能會殘餘一個暫時工作檔。下次執行時碰到殘存的暫時工作檔，程式會拒絕執行跳出。請先處理殘存的暫時工作檔。妳可以把暫時工作檔當成原來的記錄檔來用，重新反查。</p></li>
 <li><p>本程式需要很多暫存資料的空間。硬碟和記憶體比起來，價格便宜，用起來也比較省，所以我用硬碟暫存。這個程式需要原記錄檔解壓後兩倍以上的硬碟空間，才能執行（用記憶體暫存的話要用十倍）。請檢查硬碟空間夠不夠。</p></li>
 <li><p><samp xml:lang="en">reslog</samp> 尚未支援 <abbr title="internet protocol version 6" xml:lang="en">IPv6</abbr> 。</p></li>
 <li><p>我建議安裝 <a href="http://search.cpan.org/dist/File-MMagic/" hreflang="en" xml:lang="en"><samp>File::MMagic</samp></a> ，儘量不要用 <samp xml:lang="en">file</samp> 程式。 <a href="http://search.cpan.org/dist/File-MMagic/" hreflang="en" xml:lang="en"><samp>File::MMagic</samp></a> 內建的檔案類型表好像比 <samp xml:lang="en">file</samp> 程式準確。若不是 <samp xml:lang="en">gzip</samp> 或 <samp xml:lang="en">bzip2</samp> 壓縮檔， <samp xml:lang="en">reslog</samp> 會把視為當成純文字檔。若壓縮檔被誤判為圖檔， <samp xml:lang="en">reslog</samp> 會當成純文字檔，直接讀記錄，並以錯誤結束。就算錯誤也不會弄亂原記錄檔，不過多少有點麻煩。</p></li>
 </ul>
 <h2>系統需求</h2>
 <ol>
 <li><p><acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 5.8.0 以上。 <samp xml:lang="en">reslog</samp> 用三個參數的 <samp xml:lang="en">open()</samp> 來複製檔案操作，我還不知道怎麼改寫到更早的版本上執行。若妳可以改寫到更早的版本上執行，請告訴我。妳可以輸入 <q xml:lang="en"><samp>perl -v</samp></q> 查詢妳目前的 <acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 版本。如果妳沒有 <acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 或需要昇級，可以到 <a href="http://www.perl.com/" hreflang="en"><acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 網站</a>下載安裝最新版 <acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 。若妳是用 <span xml:lang="en"><abbr title="Microsoft">MS</abbr>-Windows</span> ，可以到 <a href="http://www.activestate.com/" hreflang="en"><span xml:lang="en">ActiveState</span> 公司</a>下載 <span xml:lang="en">ActivePerl</span> 安裝。</p></li>
 <li><p>需搭配的 <acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 模組：無。</p></li>
 <li><p>選配的 <acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 模組：</p>

    <p>這是檢查檔案類型用的。若沒有安裝， <samp xml:lang="en">reslog</samp> 會找 <samp xml:lang="en">file</samp> 程式代替。若還找不到， <samp xml:lang="en">reslog</samp> 會改用檔尾（副檔名）判斷檔案類型。這時若從標準輸入讀檔， <samp xml:lang="en">reslog</samp> 就無法判斷了。妳可以<a href="http://search.cpan.org/dist/File-MMagic/" hreflang="en">由 <acronym title="Comprehensive Perl Archive Network" xml:lang="en">CPAN</acronym> 模組庫下載安裝 <samp xml:lang="en">File::MMagic</samp> </a>，或用 <span xml:lang="en"><samp>CPAN</samp> Shell</span> 執行 <q xml:lang="en"><samp>cpan File::MMagic</samp></q> 安裝，或用 <span xml:lang="en"><samp>CPANPLUS</samp> Shell</span> 執行 <q xml:lang="en"><samp>cpanp i File::MMagic</samp></q> 安裝。若妳是 <span xml:lang="en">Debian/Ubandu Linux</span> 使用者，可以執行 <q xml:lang="en"><samp>apt-get install libfile-mmagic-perl</samp></q> 安裝。若妳是 <span xml:lang="en">Red Hat/Fedora/CentOS Linux</span> 使用者，可以執行 <q xml:lang="en"><samp>yum install perl-File-MMagic</samp></q> 安裝。若妳是 <span xml:lang="en">FreeBSD</span> 使用者，可以執行 <q xml:lang="en"><samp>ports install p5-File-MMagic</samp></q> 安裝。若妳是 <span xml:lang="en">ActivePerl</span> 使用者，可以執行 <q xml:lang="en"><samp>ppm install File::MMagic</samp></q> 安裝。若妳要在 <span xml:lang="en"><abbr title="Microsoft">MS</abbr>-Windows</span> 下使用 <samp xml:lang="en">file.exe</samp> 程式，可以由 <a href="http://gnuwin32.sourceforge.net/" hreflang="en-us"><span xml:lang="en">GnuWin32</span> 網站</a>下載。請確認下載後，存檔在系統的路徑下，檔名為 <samp xml:lang="en">file.exe</samp> 。</p>
    <p>建議用 <a href="http://search.cpan.org/dist/File-MMagic/" hreflang="en" xml:lang="en"><samp>File::MMagic</samp></a> 。 <samp xml:lang="en">file</samp> 程式偶爾會誤判。</p>

 <h2>安裝</h2>
 <p>若妳是由 <samp xml:lang="en">reslog</samp> 3.10 以前的版本昇級，或是由 <samp xml:lang="en">reslog.pl</samp> 3.02 以前的版本昇級，請參閱 <samp xml:lang="en">UPGRADE.zh-tw</samp> 檔的昇級說明。</p>
 <h3>以 <a href="http://search.cpan.org/dist/ExtUtils-MakeMaker/" hreflang="en" xml:lang="en"><samp>ExtUtils::MakeMaker</samp></a> 安裝</h3>
 <p><samp xml:lang="en">reslog</samp> 用 <acronym title="Practical Extraction and Reporting Language" xml:lang="en">Perl</acronym> 標準的 <a href="http://search.cpan.org/dist/ExtUtils-MakeMaker/" hreflang="en" xml:lang="en"><samp>ExtUtils::MakeMaker</samp></a> 安裝，程序如下：</p>
 <blockquote xml:lang="en"><pre>
 % perl Makefile.PL
 % make
 % make test
 % make install
 </pre></blockquote>
 <p>在 <q xml:lang="en"><samp>make install</samp></q> 前，請先確認妳有在安裝目錄存檔的權限。通常這時候要切換為 <samp xml:lang="en">root</samp> ，才能安裝存檔。</p>
 <p>若妳是用 <span xml:lang="en"><abbr title="Microsoft">MS</abbr>-Windows</span> 下的 <span xml:lang="en">ActivePerl</span> ， <samp xml:lang="en">make</samp> 請改用 <samp xml:lang="en">nmake</samp> 。 <a href="ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe" type="application/x-dosexec"><samp xml:lang="en">nmake</samp> 可由微軟的 <abbr title="File Transfer Protocol" xml:lang="en">FTP</abbr> 站下載</a>。</p>
 <p>若要安裝到其它地方，請設定好 <samp xml:lang="en">PREFIX</samp> 。例如，一般使用者，要安裝在自己的目錄下時：</p>
 <blockquote xml:lang="en"><pre>
 % perl Makefile.PL PREFIX=/home/jessica
 </pre></blockquote>
 <p>要知道更多安裝選項的細節，請參閱 <a href="http://search.cpan.org/dist/ExtUtils-MakeMaker/" hreflang="en" xml:lang="en"><samp>ExtUtils::MakeMaker</samp></a> 的說明（請執行 <q xml:lang="en"><samp>perldoc ExtUtils::MakeMaker</samp></q> ）。</p>
 <h3>以 <a href="http://search.cpan.org/dist/Module-Build/" hreflang="en" xml:lang="en"><samp>Module::Build</samp></a> 安裝</h3>
 <p>若妳喜歡，也可以用 <a href="http://search.cpan.org/dist/Module-Build/" hreflang="en" xml:lang="en"><samp>Module::Build</samp></a> 安裝，程序如下：</p>
 <blockquote xml:lang="en"><pre>
 % perl Build.PL
 % ./Build
 % ./Build test
 % ./Build install
 </pre></blockquote>
 <p>在 <q xml:lang="en"><samp>./Build install</samp></q> 前，請先確認妳有在安裝目錄存檔的權限。通常這時候要切換為 <samp xml:lang="en">root</samp> ，才能安裝存檔。</p>
 <p>若要安裝到其它地方，請設定好 <samp xml:lang="en">--prefix</samp> 。例如，一般使用者，要安裝在自己的目錄下時：</p>
 <blockquote xml:lang="en"><pre>
 % perl Build.PL --prefix=/home/jessica
 </pre></blockquote>
 <p>要知道更多安裝選項的細節，請參閱 <a href="http://search.cpan.org/dist/Module-Build/" hreflang="en" xml:lang="en"><samp>Module::Build</samp></a> 的說明（請執行 <q xml:lang="en"><samp>perldoc Module::Build</samp></q> ）。</p>
 <h2>命令列參數</h2>
 <pre>

 ./reslog [-h|-v]
 </pre>
 <dl>
 <dt xml:lang="en"><var xml:lang="zh-tw">記錄檔</var></dt>
 <dd>
 <p>要反查的記錄檔。可同時指定好幾個檔案。若沒有指定，會從標準輸入讀記錄檔，再寫到標準輸出。妳也可以設定成<q><samp>-</samp></q>，來從標準輸入讀記錄檔，從標準輸入讀取的記錄，反查後會送到標準輸出。支援 <samp xml:lang="en">gzip</samp> 或 <samp xml:lang="en">bzip2</samp> 壓縮檔。</p>
 </dd>
 <dt xml:lang="en">-o, --override <var xml:lang="zh-tw">模式</var></dt>
 <dd>
 <p>如果有同名的反查結果檔，該怎麼辦。目前有下列模式：</p>
 <dl>
 <dt xml:lang="en">o, overwrite</dt>
 <dd>
 <p>蓋掉舊檔。</p>
 </dd>
 <dt xml:lang="en">a, append</dt>
 <dd>
 <p>和舊檔加在一起。</p>
 </dd>
 <dt xml:lang="en">f, fail</dt>
 <dd>
 <p>結束程式，以免不小心破壞舊檔。預設是結束程式。</p>
 </dd>
 </dl>
 </dd>
 <dt xml:lang="en">-k, --keep <var xml:lang="zh-tw">模式</var></dt>
 <dd>
 <p>原記錄檔要怎麼處理。目前有下列模式：</p>
 <dl>
 <dt xml:lang="en">a, all</dt>
 <dd>
 <p>保留原檔。</p>
 </dd>
 <dt xml:lang="en">r, restart</dt>
 <dd>
 <p>反查後，原記錄檔歸零。</p>
 </dd>
 <dt xml:lang="en">d, delete</dt>
 <dd>
 <p>反查後，刪除原記錄檔。預設是刪除原記錄檔。</p>
 </dd>
 </dl>
 </dd>
 <dt xml:lang="en">-s, --suffix <var xml:lang="zh-tw">檔尾</var></dt>
 <dd>
 <p>反查結果檔要加上的檔尾。預設的檔尾是 <q xml:lang="en"><samp>.resolved</samp></q> 。</p>
 </dd>
 <dt xml:lang="en">-t, --trim-suffix <var xml:lang="zh-tw">檔尾</var></dt>
 <dd>
 <p>加上我們的檔尾前，先去掉的原檔檔尾。預設是不去檔尾。若妳用好幾個記錄檔處理程式處理記錄檔，可以用這個選項，去掉之前程式加的檔尾。</p>
 </dd>
 <dt xml:lang="en">-n, --num-threads <var xml:lang="zh-tw">線程數</var></dt>
 <dd>
 <p>反查時，同時執行的線程數。預設值是 10 。若不要用多線程反查，請設為 0 。系統本身要支援多線程。若系統本身不支援多線程，本選項沒有作用。</p>
