Thanks for shipping help2man, nice addition.
I guess it didn't come sooner because it had to wait locale-gettext being included.
In the same vein, I suggest to add txt2tags (also available @ slackbuilds.org) and especially po4a.
po4a has dependencies
and I would understand that Mr. Volkerding be reluctant to add it now.
But these dependencies are only for the Text module, which is not the more useful IMO.
So if that module (and corresponding tests) is removed from the source tarball, building po4a needs nothing besides what is already in -current.
