# Slackware build script for guitarix
# Originally written by Michales Michaloudes (email removed)

# Modified by B. Watson <yalhcru@gmail.com>. Modified version released
# under the WTFPL, for details see http://www.wtfpl.net/txt/copying/

# Note to self: git URL for guitarix is:
# git://git.code.sf.net/p/guitarix/git/

# 20180828 bkw: Updated for 0.37.3.

# 20180619 bkw:
# - Updated for 0.37.1.
# - Force building with bundled zita-convolver and resampler libs.
#   Previously, system libs would be linked if they were installed,
#   otherwise bundled libs were used... caused a problem if the
#   system zita-convolver was updated to an incompatible version.
# - Add config options to re-enable ladspa and lv2 mod-gui stuff that
#   used to be enabled by default in 0.36.1.
# - Add patches from upstream git, to fix segfaults when online
#   button gets clicked. Also if dbus isn't running, guitarix will now
#   actually say so, in its error message.
# - Move old changelog entries to ChangeLog.old.

# 20171223 bkw: Updated for 0.36.1.
# 20170825 bkw: Updated for 0.35.6. Install the bundled roboto font.
# 20170725 bkw: Updated for 0.35.5

# 20170710 bkw:
# - Updated for 0.35.4
# - Remove README stuff about webkitgtk, since upstream dropped it.
# - Add README.online with troubleshooting info. I had trouble
#   getting the new Online Presets stuff to work, so hopefully this
#   might help the next guy.

# 20170404 bkw:
# - Updated for 0.35.3
# - Use + rather than ; in find/chmod. Noticeably faster.

# 20170306 bkw:
# - Flip changelog comments right-side up
# - Stop writing outside of $TMP.
