# Runs Wesnoth using a clean, throwaway config directory.
#
# The configuration directory is created on your temporary
# directory (i.e. /tmp) with a unique name every time, and
# deleted when finished.
#
# Usage:
#     wesnoth-defaults <command line>
#
# Examples:
#     wesnoth-defaults ~/src/wesnoth-1.12/wesnoth
#     wesnoth-defaults ~/src/wesnoth-1.12/wesnoth -s server.wesnoth.org
#     wesnoth-defaults ~/src/wesnoth-trunk/wesnoth-debug --campaign Heir_To_The_Throne
