#               GotMail - Statistics Printing Script for GetMail
#
#             1999 by Thomas Nesges <ThomaNesges@TNT-Computer.de>
#
#------------------------------------------------------------------------------

#------------------------------------------------------------------------------
# GotMail reads a GetMail logfile (/var/log/fetchmail.log) and prints
# statistics from all sessions logged in it, either as normal text on the
# Console, or as an html-file. The parsing is done with the awk-scripts
# gotmail.awk and gotmail.html.awk.
# You can configure its output with a file gotmail.conf either in your home,
# /etc, or in /usr/local/gotmail.
#
# GetMail has to be properly installed. For HTML output the htmllib has to be
# installed in /usr/local/htmllib.
#
# If you have any changes/corrections in the script, please send me email.
