mki18n allows you to internationalize your software.  You can use it to

    37

create the GNU .po files (Portable Object) and the compiled .mo files

    38

(Machine Object).

    39

    40

mki18n module can be used from the command line or from within a script (see

    41

the Usage at the end of this page).

NOTE:  this module uses GNU gettext utilities.

    55

    56

You can get the gettext tools from the following sites:

    57

    58

   - `GNU FTP site for gettetx`_ where several versions (0.10.40, 0.11.2, 0.11.5 and 0.12.1) are available.

    59

     Note  that you need to use `GNU libiconv`_ to use this. Get it from the `GNU

    60

     libiconv  ftp site`_ and get version 1.9.1 or later. Get the Windows .ZIP

    61

     files and install the packages inside c:/gnu. All binaries will be stored

    62

     inside  c:/gnu/bin.  Just  put c:/gnu/bin inside your PATH. You will need

    63

     the following files:

    64

    65

      - `gettext-runtime-0.12.1.bin.woe32.zip`_

    66

      - `gettext-tools-0.12.1.bin.woe32.zip`_
