#
# This test generates 100 times 25 random levels and checks
# that it doesn't crash, and that it gives levels that are
# possible (in the limited sense of not having any full-
# column walls)
#
# this test accepts the following parameters:
# -wall    show the level layout
# -wind    show the level wind pattern
# -seed N  use random seed N for the generation
