# Slackware build script for cmatrix
# Originally written by Phillip Warner <email removed>
# Now maintained by B. Watson <urchlay@slackware.uk>

# Original version of the script had no license. This version is
# licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Note: there is an updated fork of cmatrix here:
# https://github.com/abishekvashok/cmatrix/
# ...but I didn't package it because "cmatrix -l" doesn't work in
# that version (shows only + - ^ characters instead of Japanese).

# 20240811 bkw, BUILD=3:
# - new maintainer.
# - add WTFPL license.
# - gzip the pcf font.
# - remove cmatrix-1.2a-find_fonts.diff (it wasn't needed).
