# Auxiliary script for regression testing environment
#
# This script transforms .in files for assembler regression testing into a list
# of command line switches, which are then passed to the assembler. This
# process is done in this way, all comments and empty lines are removed and the
# rest in then concatenated to from a single line. After this all white space
# is shortened.
#
# Software requirements:
# 	- gawk
