# Slackware build script for hxtools

# Written by B. Watson (yalhcru@gmail.com)

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

# This build includes both hxtools and the libHX library it depends
# on. In the unlikely event that someone finds another project that
# depends on libHX and wants to package it up for SBo, whatever it is
# can just list hxtools as a dependency.
