To use it in mutt:

set signature="~/Coysig"|

To use it in slrn:

set signature "/home/briac/.signature-slrn"
set editor_command "/home/briac/Coysig -s > /home/briac/.signature-slr
+n;vim +%d %s -c 'set wrap' -c 'set textwidth=72' -c 'set nocp' -c '?^

Update to echo blakem's comment: There's no strict, -w or Getopt used here because the script has been thoroughly tested by a fully-trained squad of rabid penguins. And because I didn't want to bother loading these modules everytime I send a mail or post to a newsgroup. But for anything longer, please use strict, -w and a proper option parser (Getopt::Mixed is most excellent.)
