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.
 .
 This package contains the main libraries of po4a, and the necessary
 sub-modules to handle the following formats:
 .
   - Asciidoc: Asciidoc documentation format
