# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       ttf-arphic-uming
# Descr:     Unicode Mingti (printed) TrueType Font
# URL:       http://www.freedesktop.org/wiki/Software/CJKUnifonts
# Needs:     
# Changelog:
# 0.1.20060928-1: 07/Nov/2007 by Eric Hameleers <alien@slackware.com>
#                 * Initial build.
# 0.1.20060928-2: 18/Nov/2007 by Eric Hameleers <alien@slackware.com>
#                 * Set ARCH to 'noarch' since a font is archtecture-
#                   independent.
# 0.1.20060928-3: 02/Feb/2008 by Eric Hameleers <alien@slackware.com>
#                 * Don't let fontconfig use the font as the default for
#                   sans and serif font display.
# 
# Run 'sh ttf-arphic-uming.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
