# Slackware build script for alsa-tools

# Written by B. Watson (yalhcru@gmail.com)

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

# I am *not* going to create separate packages for each of the individual
# tools, as some distros do. They're small enough that it's worth the
# tiny bit of extra disk space for unused tools, to avoid the annoyances
# of having to write and test 10 or 12 packages. For the same reason,
# the firmware is being included in the package as well.
# *** I agree.  --rworkman   :-)

# 20200224 bkw: update for 1.2.2 (firmware 1.2.1)
# 20181204 bkw: update for 1.1.7
# 20180614 bkw: update for 1.1.6
# 20171214 bkw: update for 1.1.5

# 20170313 bkw:
# - flip this changelog right-side-up :)
# - stop spamming /root/.qt/
# - not bumping BUILD, it's a trivial change

# 20170126 bkw: update for 1.1.3
# 20160109 rlw: update for 1.1.0
# 20150505 bkw: update for 1.0.29

# 20140823 bkw:
# - Add usbcore.autosuspend=-1 to tascam howto
# - Update for 1.0.28

# 20140219 bkw: fix .desktop files so they validate
