# Description:
# Write a mmp file
# Template substitution values are partially deduced from 'datafiles'.
# Substitutions are:
# $FILENAME: the name of the file generated.
# $SOURCES: source files to add.
# $GENERATE_TIME_STAMP: timestamp showing when the generator produced the file

# SOURCEPATH and SOURCE specifiers to the mmp file. Entries can have a 'Postfix' which will be appended to source file names.
