If you want to translate your wiki into another language, there are essentailly three peices needed for a complete translation:

1. The messages in the ikiwiki program itself need to be translated. Ikiwiki is internationalised, and most such messages are already marked with gettext(). THe source tarball includes a creates a po/ikiwiki.pot that can be copied and translated as a po file. All very standard.

   Note that a few things in the source are not currently translated.
