Submitted: taylor@hplabs Mod.sources: Volume 6, Issue 6 Archive-name: maildigest [ The mail.digest.m program refers to mailx; change this to Mail if you have it. If you have neither, you'll have to do something else to get the subject lines in there. Change the "SEE ALSO" in digest.1 also, which has to be the chattiest manpage in Unix(tm) history. --r$] --------------------------------cut here-------------------- # This is a shell archive.
