hi,

what dou you think about including a page with the available languages
into the header, to avoid inconsistencies. a prominent inconsistent
example ishttp://wiki.debian.org/DebianIntroductionSpanish,
containing only 50% of the available transaltions.

for a usage example see http://wiki.debian.org/DebianIntroduction/langs
used in http://wiki.debian.org/de/DebianIntroduction.

kr, rupert.
