# Helper script for setting up a wacom tablet.
# USAGE: wacom [-r] [-c <config>]
# FLAGS:
#   -r: rotate the board's input 180°, useful if using the board upside down to
#   its assumed usage orientation.
#   -c: uses one of the hardcoded configurations for stylus button bindings.
# NOTE:
#   The configs are currently hardcoded for my personal preferences in several
#   programs/websites for the One by Wacom tablet.
# CONFIGS:
#   aww: (obsolete) for the AWW shared whiteboard.
#   krita: the Krita drawing program.
#   miro: for the Miro shared whiteboard.
