po4a - Versatile PO to/from other documentation formats converter

po4a (PO for anything) eases translations and their maintenance,
allowing gettext's usage on unexpected areas like documentation.

In po4a each documentation format is handled by a module, that
converts this format to/from PO. Formats included in po4a-0.45 are:
BibTex, Dia, Halibut, KernelHelp, LaTeX, Man, POD, SGML, TeX,
Texinfo, Text, WML, XHTML, XML.

man pages are encoded in UTF-8. To read them in other languages than English,
do this for instance:
LANG=ru_RU.utf8 GROFF_ENCODING=utf8 man <man page>

WARNING: run po4a.SlackBuild as root (su -) not with only root privileges
(su), otherwise test #24 will fail.
