# Slackware build script for xmms-ladspa

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

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

# Notes:
# - The source includes its own ladspa.h, which is why ladspa_sdk isn't
#   listed in REQUIRES.
# - Certain ladspa plugins will make xmms segfault when the xmms
#   plugin tries to enumerate all the plugins available. guitarix's
#   plugins are the only ones on my system that do this. All the
#   other SBo packages that install ladspa plugins seem OK, so the
#   "fix" for this is (for now anyway) just to have xmms-ladspa skip
#   any plugin with "guitarix" in its name.
# - The source is called xmms_ladspa. I chose to use xmms-ladspa for
#   PRGNAM so it'll match all the other xmms-* builds on SBo.
