It is a common feature of applications (whether run directly, or via the
Web) for them to be "localized" -- i.e., for them to a present an English
interface to an English-speaker, a German interface to a German-speaker,
and so on for all languages it's programmed with. Locale::Maketext is a
framework for software localization; it provides you with the tools for
organizing and accessing the bits of text and text-processing code that you
need for producing localized applications.

In order to make sense of Maketext and how all its components fit together,
you should probably go read Locale::Maketext::TPJ13, and _then_ read the
following documentation.

You may also want to read over the source for 'File::Findgrep' and its
constituent modules -- they are a complete (if small) example application
that uses Maketext.
