+"""
+mki18n allows you to internationalize your software. You can use it to
+create the GNU .po files (Portable Object) and the compiled .mo files
+(Machine Object).
+
+mki18n module can be used from the command line or from within a script (see
+the Usage at the end of this page).
+
+ Table of Contents
+ -----------------
+
+ makePO() -- Build the Portable Object file for the application --
+ catPO() -- Concatenate one or several PO files with the application domain files. --
+ makeMO() -- Compile the Portable Object files into the Machine Object stored in the right location. --
+ printUsage -- Displays how to use this script from the command line --
+
+ Scriptexecution -- Runs when invoked from the command line --
+
+
+NOTE: this module uses GNU gettext utilities.
+
+You can get the gettext tools from the following sites:
+
+ - `GNU FTP site for gettetx`_ where several versions (0.10.40, 0.11.2, 0.11.5 and 0.12.1) are available.
+ Note that you need to use `GNU libiconv`_ to use this. Get it from the `GNU
+ libiconv ftp site`_ and get version 1.9.1 or later. Get the Windows .ZIP
+ files and install the packages inside c:/gnu. All binaries will be stored
+ inside c:/gnu/bin. Just put c:/gnu/bin inside your PATH. You will need
+ the following files:
+
+ - `gettext-runtime-0.12.1.bin.woe32.zip`_
+ - `gettext-tools-0.12.1.bin.woe32.zip`_
+ - `libiconv-1.9.1.bin.woe32.zip`_
