# 20220404 bkw: Modified by SlackBuilds.org, BUILD=2:
# - strip the python interpreter and one shared lib that weren't already.
# - remove the broken symlinks in the icons dir. upstream doesn't include
#   PNG icons (I assume it did at one time), only an SVG one.
# - add SlackBuild to doc dir.

# Thanks to Giorgio Peron <giorgio.peron@gmail.com> for some build tips
