+This is Debian/GNU Linux's prepackaged version of GNUPG, a free PGP
+replacement. As you can see from the version number, the program may
+have some bugs and some features may not work at all.
+
+This package was put together by me, James Troup
+<james@nocrew.org>, from the sources, which I obtained from
+ftp://ftp.guug.de/pub/gcrypt/gnupg-0.9.0.tar.gz.  The changes were
+minimal, namely:
+
+- adding support for the Debian package maintenance scheme, by adding
+  various debian/* files.
