Before The Wailer, Tagit was my first
program for the Galletas BBS. It works pretty
simply: takes randomly a paragraph from a tags file, it appends it to
the user signature and adds it to the end of each email message. With a
bit of editing, it can be used with mutt by adding the following line
to .muttrc:
send-hook . set signature=tagit|
Tagit uses two files: .signature and
.quotes, both living the user $HOME. The first is the usual
signature and the second is a simple text file where the paragraphs are
separated from each other by a blank line. The first line of the file, if
not empty, is appended to the end.
