/*********************************************************
Adds a version string to an object file that can be
read with the "vers" CCS command-line program.

The string is placed in a new section named "VERSION",
so that it can easily be moved in memory or discarded.

usage:
	VERSION(id, rev, tag)
where
	id is a module variable name prefix
	rev is a string, a module revision number
	tag is a string, a revision control tag

/*
VERSION(id, rev, tag)
 Initialize an int array named <id>_version with a character string
 in the following format:
	Id:<id> Rev:<rev> Tag:<tag> Built: <date> <time>

 The rev and tag arguments are constant character strings.

 e.g. if "file.c" contains:
	VERSION(MP3_TI, "1.01", "RELEASE1");

 then "vers version.obj" will produce, e.g.:
        Id:MP3_TI Rev:1.01 Tag:RELEASE1 Built:Dec 18 2001 18:47:34
