# This script installs a user selected theme file for all existing
# PlayOnLinux wine prefixes.
# The purpose of this script is to automate theme selection process
# in a case user has many wineprefixes which would otherwise
# require manual tweaking, individually.
#
# USAGE: Change your theme preferences here and then run the script.
#
# NOTE: If you change VistaPerfection theme to another one, please
# make sure you change corresponding registry values below!
