 =head1 NAME
 
-pgp-clean -- remove all non-self signatures from key
+pgp-fixkey -- remove broken packets from keys
 
 =head1 SYNOPSIS

-=item B<pgp-clean> I<keyid> [I<keyid> ...]

 =head1 DESCRIPTION
 
-B<pgp-clean> takes a list of keyids on the command line and outputs an
-ascii-armored keyring on stdout for each key with all signatures except
-self-signatures stripped.  Its use is to reduce the size of keys sent out after
-signing (e.g. with B<caff>).
+B<pgp-fixkey> removes broken packets from keys in the GnuPG keyring that make
+GnuPG spew ugly warnings.  It optionally takes a list of keyids on the command
+line and only cleans those keys.
