# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        terminus-font
# Descr:      a clean fixed width font
# URL:        http://www.is-vn.bg/hamster/jimmy-en.html
# Needs:      
# Changelog:  
# 4.26-1:     04/Aug/2008 by Eric Hameleers <alien@slackware.com>
#             * Initial build. Thanks much to font author Dimitar Zhekov
#               who offers a SlackBuild on his site! It gave me a head start
#               so I added Dimitar's copyright to the script's header.
# 
# Run 'sh terminus-font.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'. 
#
