"""Builds a new translation file with the target of the input language as
source language.
Ensure that the two po files correspond 100% to the same pot file before using
this.
To translate Kurdish (ku) through French::
po2swap -i fr/ -t ku -o fr-ku
To convert the fr-ku files back to en-ku::
po2swap --reverse -i fr/ -t fr-ku -o en-ku
See: http://translate.sourceforge.net/wiki/toolkit/poswap for further examples and
