# Slackware build script for sfarkxtc

# Originally by Ben Colliver. Rewritten and now maintained by B. Watson
# (urchlay@slackware.uk).

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

# Note: there's a .sfark file to test with, here:
# https://slackware.uk/~urchlay/src/OPL-3_FM_128M.sfArk
# Originally downloaded from:
# https://woolyss.com/chipmusic-soundfonts.php

# 20260301 bkw:
# - take over maintenance.
# - add license (WTFPL).
# - build from latest (2018) source rather than use a binary from 2007.
# - add man page.
# - since we're building from source, x86_64 is now supported.
