# ToDo list:
#
# - figure out runtime dependencies
# - try to move Lightworks to /opt as it is only available as a pre-compiled binary
#   (not sure if possible since it is intended to be installed to /usr)
# - try to silence QA notices
# - figure out if high load/memory usage (memleak?) of ntcardvt process are specific to Gentoo
