Date: Tue, 10 Jun 2008 22:25:32 -0400
Subject: More cleanup of scripts - fixed bug in gpg2ssh_tmp call - broke out
 update_authorized_keys function - cleaned up gen_key function for server   -
 added possible "Revoker:" parameter we might use - started gen_ae_subkey
 function that for some reason isn't working   yet.
