Keyword expansion fun

Certain keywords will be automatically expanded in source files:

$Id$ -- filename, revision, date, author, state
$Date$ -- date and time the file was checked in
$Author$ -- author of the file
$Revision$ -- revision of the file
$Log$ -- causes log entries to be appended

An example:

/* $Id: hello.c,v 1.3 1996/11/15 22:14:05 swetland Exp $
 * $Date: 1996/11/15 22:14:05 $
 * $Author: swetland $
 * $Revision: 1.3 $
 */

main()
{
        printf("Hello World");
}

If you embed this strings in a string constant, the rcs ident command can be used to get the version of an executable. Example, hello.c:

static char *id = "$Id: hello.c,v 1.3 1996/11/15 22:14:05 swetland Exp $";
main()
{
	printf("Hello, World!");
}

Try typing:

$ ident hello
hello:
     $Id: h.c,v 1.3 1996/11/15 22:14:05 swetland Exp $
