gnupg-idea - Debian package for using idea with gnupg
-----------------------------------------------------

The gnupg-idea package (without the IDEA source code) is based on
gpg-rsaidea-2.1 by Tom Lees <tom@lpsg.demon.co.uk> and Josip Rodin
<jrodin@jagor.srce.hr>.

Arthur de Jong <adejong@debian.org> stripped out the RSA stuff and
pgp wrapper examples that are obsoleted by inclusion of RSA in gnupg
and the pgpgpg package and added functions for downloading the idea
source at build time.
