gettext: Programmers for other Languages

 
 15.2 The Programmer’s View
 ==========================
 
    For the programmer, the general procedure is the same as for the C
 language.  The Emacs PO mode marking supports other languages, and the
 GNU ‘xgettext’ string extractor recognizes other languages based on the
 file extension or a command-line option.  In some languages, ‘setlocale’
 is not needed because it is already performed by the underlying language
 runtime.
