# palm_simple_run - a simple method for running the palm code without
#                   using the mrun script
#
# This script runs the palm code in a unique subdirectory (OUTPUT...,
# current time/date and number of processors are part of the subdirectory
# name).
# It requires that palm has been installed with command
# palm_simple_install and that the executable palm has been created
# with make in directory  ...../MAKE_DEPOSITORY_simple
