# Slackware build script for mididings

# 20211230 bkw:
# - updated for v20151117_bbec99a.
# - don't install doc/*, it's the *source* for the documentation.
# - do install doc/examples, it's just python code.

# Notes to self:

# The documentation for mididings requires an archaic version of
# Sphinx to build it. Modern Sphinx (4.2 on SBo) won't work. Rather
# than diving into that rabbit hole, I'm just adding a link to the
# docs on upstream's site.

# Debian has man pages for mididings and livedings, but they're
# horribly outdated (2010). Don't include here.

# Previous versions were built with libsmf, and could process MIDI
# files as-is. This version needs pysmf for that purpose, and we don't
# (yet) have it on SBo, so there's no MIDI file support. However, you
# could always use a MIDI player to play a file and connect its output
# to mididings, so it's not a show-stopper.
