# Slackware build script for rxvt

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# This is loosely based on Pat Volkerding's rxvt from Slackware 14.2's
# patches/ (same ./configure options and patches). Since his last BUILD
# was 5, I'm submitting this with BUILD=6 to start out with.

# The original upstream site is long gone. I was gonna link to an
# archive.org copy of it for the screenshots in the HTML doc, but
# the screenshot (the only one) isn't archived. So the docs have dead
# links, *shrug*.
