Detailed Description

Provides a simple gettext replacement that works independently from the system's gettext abilities. It can read MO files and use them for translating strings. The files are passed to gettext_reader as a Stream (see streams.php)

This version has the ability to cache all strings and translations to speed up the string lookup. While the cache is enabled by default, it can be switched off with the second parameter in the constructor (e.g. whenusing very large MO files that you don't want to keep in memory)
