# NOTE: This is a plugin to enable uploading of Turtle Art projects to
# Facebook. It currently works for the GTK3 version of Turtle Blocks and
# only from the GNOME desktop.
# USAGE: Download this file into the gnome_plugin directory; make sure the
# filename is fb_plugin.py (Mediawiki capitalizes the first letter of files).
# When you launch TA from the GNOME desktop by running turtleblocks.py
# you should see a new menu, Facebook, which allows you to upload your
# project. Please report any problems to rgs and walter.
