+=head1 NAME
+
+B<gpg-key2ps> - generates a PS file from a GnuPG keyring
+
+=head1 SYNOPSIS
+
+B<gpg-key2ps> [B<-r> I<revoked-style>] [B<-p> I<papersize>] I<keyid-or-name> [ I<...> ]
+
+=head1 DESCRIPTION
+
+gpg-key2ps generates a PostScript file with your OpenPGP key fingerprint (repeated
+as often as it fits) useful for keysigning parties. The only argument is the same
+as you would pass to GPG's list-keys command, either a key-id or a (partial) name.
+The PS data is written to stdout.
+
+=head1 OPTIONS
+
+=over
+
+=item B<-p> B<--paper-size> I<paper-size>
+
+Select the output paper size. Default is to look into /etc/papersize or A4 if
+libpaper isn't installed.
+
+=item B<-r> B<--revoked-style> I<revoked-style>
+
+Select how to mark revoked UIDs and subkeys. Five styles are available:
+ B<hide> don't show at all (default),
+ B<show> show normally,
+ B<grey> display in 50% grey,
+ B<note> add "[revoked]", and
+ B<strike> strike through.
+
+=item I<keyid>
+
+Keyids to print. Multiple can be separated by spaces.
+
+=item B<-h> B<--help>
+
+Print usage and exit.
+
+=item B<-v> B<--version>
+
+Print version and exit.

+B<gpg-key2ps> prints plain fingerprint slips. If you are looking for something
+more stylish, look at these latex templates for business cards that also
