GNU tools and libraries for localized translated messages

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.
