- # Subject: MH utility to delete duplicate messages in a folder
- # Date: Wed, 19 Aug 92 11:48:45 -0400
- # From: Bob Munck <munck@Stars.Reston.Unisys.COM>
- #
- # I debated using "$1" everywhere I have "+$1", since the user
- # would then need the "+" and would be following MH conventions
- # more closely. I suppose a real convention-following utility
- # would also allow defaulting by using Path from ~/.mh-profile
- # to find context and getting Current-Folder from it.
