0.5 (December 16, 1993)
	Many bug-fixes
	Initialization code revamped; see $root.initialize(),
		$root.uninitialize(), $root.init(), and init methods
		on objects.  Also look at $located.uninit().
	Connections now forward text to users instead of changing the
		handler object to the user object.  This allows more
		flexible handling of connections and allows @quit to
		affect only one connection.
	Embryonic editor support.

0.4 (November 25, 1993)
	Protocols: see NOTES.
	Initialization is now done with no arguments; you do
		modification after objects are initialized.
	Exits are broken; I'll fix later.
	lock.c-- frob constructors rewritten for 0.8.
	substring() renamed to substr() for 0.9.

0.3 (November 2, 1993)
	Lots of changes and fixes.  @dig is working now, more or less.

0.2.2 (October 16, 1993)
	Bug fixes:
		remove_command() on commands
		Bug in match_environment() when string wasn't found

0.2.1 (October 11, 1993)
	Many bugs fixed, with command-matching, location tracking,
		and in other places.  0.2 didn't work at all.

0.2 (October 9, 1993)
	$player.translate() eliminated in favor of pattern-matching
		commands.  add_command() requires a third argument,
		either 'template or 'pattern.  Look at the core for
		examples.
	Somewhat improved documentation, although protocols could use
		a bit more work.

0.1 (October 6, 1993)
	Initial release
