# palm_simple_run - a simple method for running the palm code without
#                   using the mrun script
# $Id: palm_simple_run 421 2010-01-25 15:50:10Z raasch $

     # 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 ~/palm/current_version/MAKE_DEPOSITORY_simple
