Info request.

Is it possible to use procmail to forward only the attachment of an email to
a program?
If possible how? How do I have to modify my .procmailrc file?
Here's the copy of the .procmailrc file I'm currently using:

PATH=/bin:/usr/local/bin
MAILDIR=/aula/i094246/mail
# LOGFILE=$MAILDIR/procmail.log
SHELL=/bin/sh
:0
* ^From:.*mail
/dev/null
:0 c:
| /aula/i094246/genesis

I would be very pleased to receive an answer.
Thanks.
