`@documentlanguage CC': Set the Document Language
=================================================
The `@documentlanguage' command declares the current document
language. Write it on a line by itself, with a two-letter ISO-639
language code following (list is included below). If you have a
multilingual document, the intent is to be able to use this command
multiple times, to declare each language change. If the command is not
used at all, the default is `en' for English.
At present, this command is ignored in Info and HTML output. For
TeX, it causes the file `txi-CC.tex' to be read (if it exists). Such a
file appropriately redefines the various English words used in TeX
output, such as `Chapter', `See', and so on.
It would be good if this command also changed TeX's ideas of the
current hyphenation patterns (via the TeX primitive `\language'), but
this is unfortunately not currently implemented.
Hereare the valid language codes, from ISO-639.
