The GNU gettext package provides a set of tools and documentation for producing
multi-lingual messages in programs. Tools include a set of conventions about
how programs should be written to support message catalogs, a directory and
file naming organization for the message catalogs, a runtime library which
supports the retrieval of translated messages, and stand-alone programs for
handling the translatable and the already translated strings. Gettext provides
an easy to use library and tools for creating, using, and modifying natural
language catalogs and is a powerful and simple method for internationalizing
programs.

If you would like to internationalize or incorporate multi-lingual messages
into programs that you're developing, you should install gettext.

Build Option:
--with csharp Enables C# support in gettext
--without java Disables Java support in gettext
