tools to ease the translation of documentation

 po4a eases the translation of documentation and other textual document.
 Even more interestingly, it makes it easy to maintain these
 translations when the original document changes. This is done by
 using the gettext tools in this new domain.
 .

 sub-modules to handle the following formats:
