# Script to determine which source files need to have new messages 
# substitued into them and accomplish those substitutions.  The 
# files on the command line will be run thru genmsg, and those 
# files that exhibit actual differences will then be checked out, 
# and really run thru genmsg, and then checked back in.
#
# To use the script, you must scccs get all of the source files you wish
# to process, as well as dtcm.msg and project.set.  When ready, one runs 
# "process_msg *.c".  It will look thru all the .c files, looking to 
# see which ones have unassigned message id's, and check those files out.  
# It will then run those files thru genmsg, and regenerate the dtcm.msg 
# file.  You must delta in the processed .c files as well as project.set 
# and dtcm.msg.  A bunch of old .msg files will remain in the directory.
# The old message file will be stored in dtcm.msg.orig.
