Andy slapped this together and I reckon it's worth putting on
              our funky clunky cat-faq :)
              some dodgy notes about setting up procmail, qmail, pine on
              CAT.
              1. Get a copy of a procmail rc file (rc = resource). See
              /home/andy/.procmailrc for an example - also "man procmail"
              works. you need a file called .procmailrc in your home
              directory.
              2. start pine, make the folders through the "add folder"
              interface in your inbox. The folder names must correlate with
              the name of the folders you specify in the .procmailrc
              3. create a .qmail file in your home directory with | preline
              procmail in it.
              4. enjoy procmail filtering on your mails.
