# Since version 1.23 it is possible to build/use SciDAVis with Python 3 - just use
# PYTHON3=yes before execute scidavis.SlackBuild. Default is to use python 2 (PYTHON3=no).
# *** It does not build using Python 3 in Slackware 14.2 or previous because PyQt was not built with
# Python 3 support. I'm adding this here because I know it will be useful in the future and for the
# tests currently done in -current
