# palm_simple_install - a script for simple installation and compilation of
#                       the palm code without using mbuild
# This script creates (from the working copy of the palm repository)
# a subdirectory MAKE_DEPOSITORY_simple which contains a copy of the
# palm source code and  a modified makefile which loads required compiler
# and preprocessor settings via "include MAKE.inc"

# Options: -i <include file>
#          one of the include files in ~/palm/current_version/trunk/INSTALL

# Last changes:
# 25/01/10 - Siggi - Generating the first version
# 18/03/10 - Siggi - switch to palm/current_version removed: working
#                    copy can be in any directory
