# Script to configure, build, and install the CRTM library.
#
# * This script is a wrapper for the basic steps detailed in the README file.
#
# * Default installation structure is "NCO style" ala /nwprod/lib.
#
# * The build configuration setup is specified via files in the config-setup/ 
#   subdirectory that are sourced within this script.
#
# * The installation directory is ${PWD}
