Anarchopedia is using ISO 639-2 (three letters) codes from its
beginning. Two letters codes are generally Apache config hack for
compatibility with Wikipedia (interwiki links also have compatibility
with Wikipedia and they are usually used, even three letters codes
should be used). Long time ago I asked Andre Engels how to change
that, but I forgot how to do that. So, may someone fix it? Here is the
list of the pairs:
ar:ara
id:ind
bs:bos
zh:chi
da:dan
de:deu
el:ell
es:spa
eo:epo
fr:fra
hr:hrv
it:ita
ja:jpn
lt:lit
nl:dut
no:nor
nn:nno
pl:pol
pt:por
ro:rum
ru:rus
sr:srp
sh:nsh
sv:swe
(nsh is not an ISO 639-2 code)
