How to help with GnuPG documentation?

[A.M. Kuchling]

I'd like to help with updating GnuPG's documentation and/or the web
site.  What tasks need to be done?  I'm happy to write new material,
check that existing text and examples are still correct for GnuPG 2,
convert the documentation from one format to another, update the FAQ,
etc.

For example, I noticed the GNU Privacy Handbook has a copyright date
of 1999.  Does it need updating for current versions of GnuPG?  If yes,
where is the master Texinfo source?  I've been unable to locate it.

(My writing background: I've written some pieces of the official
Python documentation, such as the What's New in Python 2.x and some of
the HOWTOs, but now am looking for a new documentation project to work
on.)

Thanks!
