#
# This is a basic interface to append an Oddmuse wiki page. I used
# that in order to keep a list of things to do or remember (like url). 
# Very nifty if you have only an SMTP client available. 
# The data appended is from the "Subject" header only.
# 
# The installation can be done via procmail or a mail alias entry like :
# 
# anemailalias: "|perl /usr/bin/oddmail.pl"
