# 17.05.96 exit added.
# 19.09.96 Peter Jaeckel <atmpj@ermine.ox.ac.uk>
#          -metoo option included.
#          Set up your .pinerc with:
#             sending-filters=/home/pjaeck/bin/pgpencrypt -metoo _RECIPIENTS_,
#                       /home/pjaeck/bin/pgpsign
#          [Obviously, you substitute /home/pjaeck/bin/pgpencrypt
#           with your path to this file]
#          As pine stores emails that you send out in the filtered
#          form, without the -metoo switch you as the sender
#          can never decode your own messages.
# 19.03.97 Check return value of pgp.
#          Locate TMPFILE in a secure directory.
# 20.03.97 New bug introduced yesterday fixed.
