	* Version 2.1.

	* rhparse.c: now allows underscores in identifiers (not just
	alphanumerics).

	* sample.rhrc: added xdev function.

	* rhparse.c: added support for hex constants. Wouldn't have been
	much fun testing for a specific device without that...

	* rh.1: documented change to `-h', and emphasised that `-r' does
	the *opposite* of what it does in just about everything else. :-)
	Also `fixed' a couple of strangely-phrased bits.

	* Renamed rh.man to rh.1, and rhrc to sample.rhrc.

	* rh.c: now quits after printing usage message (`-h'). Also sorted
	options in usage output, and emphasised that [yyyy/mm/dd] needs
	4-digit year.

	* getopt.c: removed, it was buggy and not needed for Linux anyway.

	* Added new Makefile.

	* Various small cleanups to get it working on Linux.
