18.1 @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.
