# This provides a quick sanity check on the message types in
# the header file. The check is only to ensure that there are
# no duplicate constant names or values for any #define in the file.
#
# By default RIC_message_types.h is parsed, but it will accept the 
# filename as the first positional parameter on the command line should
# it be necessary.
#
# The script exits with a 0 return code if all is good, 1 to indicate errors.
#
# CAUTION:  this breaks if any define is more than a simple key/value
#	pair in the header file.
