# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        ecofont
# Descr:      TrueType font based on Vera Sans using ~20% less ink
# URL:        http://ecofont.nl/ecofont_en.html
# Needs:      
# Changelog:  
# 2.00-1:    29/Nov/2008 by Eric Hameleers <alien@slackware.com>
#             * Initial build (fontfile timestamp "2008-11-14 11:19").
# 
# Run 'sh ecofont.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'. 
#
# -----------------------------------------------------------------------------

# Set initial variables:

PRGNAM=ecofont
