# Slackware build script for qtads

# Both qt4 and qt5 are supported by upstream, so this script allows for
# both. Not sure why anyone really cares (I'm pretty much GUI-insensitive,
# plus I hate waiting for qt5 to build), but eventually Pat will probably
# replace qt4 with qt5 in Slackware. When that happens, this script will
# still be usable.
