+``obasync`` - Office Basic Macro Source Synchronizer
+====================================================
+
+DESCRIPTION
+-----------
+
+``obasync`` is an OpenOffice/LibreOffice Basic macro source
+synchronizer.  It synchronizes your Basic macros with your local
+project files.
+
+
+Given the following source files:
+
+* Directory: ``MyApp``
+* Files: ``MyMacros.vb`` ``Utils.vb`` ``Registry.vb`` ``Data.vb``
+
+Running ``obasync`` will synchronze them with the followin macros:
+
+* Library: ``MyApp``
+* Modules: ``MyMacros`` ``Utils`` ``Registry`` ``Data``
+
+If the Basic library ``MyApp`` does not exist, it will be created.
+Missing modules will be added, and excess modules will be removed.
+
+And vice versa.  Given the following macros:
+
+* Library: ``MyApp``
+* Modules: ``MyMacros`` ``Utils`` ``Registry`` ``Data``
+
+Running ``obasync --get`` will synchronze them with the following
+source files:
+
+* Directory: ``MyApp``
+* Files: ``MyMacros.vb`` ``Utils.vb`` ``Registry.vb`` ``Data.vb``
+
+Missing source files will be added, and excess source files will be
+deleted.
+
+
+INSTALL
+-------
+
+You can install ``obasync`` with ``pip``.  Uses the ``python``
+executable that comes with your OpenOffice/LibreOffice installation
+when possible.
+
+* OpenOffice 4 on Linux::
+
+    /opt/openoffice4/program/python `which pip` install obasync
+
+* LibreOffice 5.x on Linux::
+
+    /opt/libreoffice5.*/program/python `which pip` install obasync
+
+* Linux vender OpenOffice/LibreOffice installation::
+
+    pip install obasync
+
+* OpenOffice on MacOSX relies on the system ``python`` installation::
+
+    sudo pip install obasync
+
+* LibreOffice on MacOSX:  There is no simple ``pip`` way to install
+  ``obasync``.  However, you can still download the script and run
+  it with the ``python`` executable that comes with your LibreOffice
+  installation.  See below.
+
+* OpenOffice/LibreOffice on MS-Windows:  You can still install
+  ``obasync`` with ``pip`` from your OpenOffice/LibreOffice
+  installation.  However, it would be much asir to just download the
+  script and run it with the ``python`` executable that comes with
+  your OpenOffice/LibreOffice installation.  See below.
+
+To download the package or the source script:
+
+* Python package: https://pypi.python.org/pypi/obasync
+* Source directory: https://github.com/imacat/obasync
+
+
+OPTIONS
+-------
+
+::
+
+  obasync [options] [directory [library]]
+
+directory
+   The project source directory.  Default to the current working
+   directory.
+
+library
+   The name of the Basic library.  Default to the same name as the
+   project source directory.
+
+-g,--get
+   Download (check out) the macros from the OpenOffice/LibreOffice
+   Basic storage to the source files, instead of upload (check in).
+   By default it uploads the source files onto the
+   OpenOffice/LibreOffice Basic storage.
+
+-p,--port N
+   The TCP port to communicate with OpenOffice/LibreOffice.  The
+   default is 2002.  You can change it if port 2002 is already in use.
+
+-x,--ext .EXT
+   The file name extension of the source files.  The default is
+   ``.vb``.  This may be used for your convenience of editor syntax
+   highlighting.
+
+-e,--encoding CS
+   The encoding of the source files.  The default is system-dependent.
+   For example, on Traditional Chinese MS-Windows, this will be
+   CP950 (Big5).  You can change this to UTF-8 for convenience if you
+   obtain/sychronize your source code from other sources.
+
+-r,--run Module.Macro
+   Run he specific macro after sychronization, for convenience.
+
+-h,--help
+   Show the help message and exit
+
+-v,--version
