# Description
#     Run either Allwclean, Allclean or default cleanCase in current directory
#     and all its subdirectories.
#
#     When an argument is provided, it is treated as a directory name.
#     If an option (eg, -self) is provided, it suppresses calling
#     Allwclean or Allclean (ie, to avoid recursion)
#

# Simple option/argument parsing.
# By default use Allclean, Allwclean when present
#
# If an argument is supplied, treat as a change directory
#
# If an option (eg, -self) is provided,
# do not execute ./Allwclean or ./Allclean (to avoid recursion)
