# Slackware build script for jack-tools

# 20151110 bkw:
# - Updated for 20141211. This is the date of the latest darcs
#   commit. Note that the c-common/ in the source tarball is the
#   old one (from my jack-tools-20130616.tar.gz), since jack-tools
#   won't compile against the latest c-common. Only jack-scope
#   and jack-play have changed.
# - Add capability stuff.

# 20170127 bkw:
# - Updated for 20170117 (latest commit). Also updated c-common to
#   latest.
# - Added man pages for the new jack-data and jack-lxvst utils.
# - Added VST headers to get jack-lxvst to build. Not sure the
#   licensing status of these, but they were cloned from a public
#   github repo.
