Changes
-------

VT 2.15 (3/12/93)
	VT now supports the telnet protocol, and the telnet ECHO and EOR
		options.
	IAC GA and, if it's turned on, IAC EOR function as prompt
		terminators.  Prompts go to a remote's promptread
		function.
	rmt_promptread(), set_promptread(), rmt_echo(), and rmt_eor()
		added.
	Display bug related to prompt changes fixed.
	Bug in executing the display hook in window.vtc fixed.
	Bug in termcap code fixed.
	Bug in input_waiting() primitive on files fixed.
	Bug in parser fixed (causing various problems, including memory
		corruption on some platforms).
	Bug in interpreter fixed, could cause memory corruption.
	Bug fixed in parsing octal digits.
	Added LP world type.
VT 2.14.2 (1/24/93)
	(This release was faulty and was removed from public ftp sites.)
	Bug fixed in + operation involving out-of-bounds string pointers
		on left hand side of assignment.
	Bug fixed in window redistribution code to prevent single-line
		windows when the screen is resized.
	A couple of potential bugs fixed regarding reference counts.
	Dependency information included in moo.vtc extras file.
	cool.vtc file added in extras directory, and moo.vtc adjusted.
	log_cmd.vtc file added in extras directory.
	Bug fixed with mush_redo_wh processing in mush.vtc in extras.
	Bugs fixed in distribution with /quote parsing and the /world
		command.
VT 2.14.1 (12/5/92)
	Bug fixed with doubling stack at a certain time
	Distribution load path order modified
	moo.vtc file added in extras directory
VT 2.14 (11/30/92)
	Log file now appears on status line while logging.
	Extra file 'filter' added to filter mud command output
VT 2.14 beta (10/12/92)
	Added: Optional arguments to functions can follow a '/'.  Example
		is process_cmdline() in command.c.  Optional arguments have
		value NULL if not specified.  Also added a short form for
		functions which only return an expression.
	Changed: load_cmd() ignores lines starting with #; can /ungag
		by pattern; startup code (see docs; shouldn't affect most),
		^P remembers partial lines typed
	Removed: strsub() and strisub() primitives
	Fixed: /more, core dump on ESC K (BHOME edit function)
VT 2.13 alpha 4 (7/9/92)
	Fixed: bugs in distribution, compile-time problems, error 
		message for - primitive
VT 2.13 alpha 3 (7/6/92)
	Fixed: compile-time problems (esp. prototypes), connect() error
		message, bug in distribution /repeat
VT 2.13 alpha 2 (6/30/92)
	Fixed: bug in read/pass loops
	Distribution: get_bracketed() moved to extension module
VT 2.13 alpha 1 (6/28/92)
	Fixed: hostname lookup, edfunc(), insert(), set_kpos(), 
		strsub(), strisub(), acopy(), BHOME, editing
		function, divide-by-zero, console, window, manager,
		compiler error handling, regexps, other bugs
	Removed: placing remote names on divider line, remote names,
		(L)ist option in console, strichr(), strrichr(),
		strrstr(), strristr(), listfunc(), find_kfunc(),
		kfunc_name(), chdir(), set_active(), set_prompt(),
		set_kbuf(), set_kpos(), logical XOR operator (^^),
		systime builtin
	Combined: bind_key() and bind_func() into bind();
		set_win_obj() and set_rmt_obj() into set_obj();
		win_obj() and rmt_obj() into obj(); give_rmt() and
		give_win() into pass(); read() and read_rmt() into
		read(); bold_on() and bold_off() into bold()
	Added: base() gets base of string/array pointer, garbage()
		does garbage collection on arrays, redraw and
		disconnect hooks, smatch() for simple string
		comparisons, assignment to builtin objects, errflag
		and errmsg builtins, reread() to patch queue-ordering
		bug with read/pass loops, new_assoc() and lookup() 
		and -> operator for property lists
	The += operator is no longer to an exception to the assignment
		rule; that is, "a += b" is now like "a = a + b" and
		not "strcat(a, b)".
	Hooks are automatic calls to VTC functions when the screen is
		redrawn automatically (i.e. not by a call to the
		redraw editing function) or when remotes are
		disconnected under any circumstances.  The VTC
		functions are redraw_hook() and disconnect_hook().
	callv() is slightly more flexible (see docs)
	Reversed order of arguments to getch() so window comes second
	Allowed use of primitive names as variables
	Improved error messages, in interpreter and compiler
	Debugging code now acts at compile-time to identify global
		variables.
	Interpreter-level debuggingcode deleted; compiler-level
		debugging code added (displays global variables
		created)
	Restricted echo() and send() to require window/remote argument
		as first argument (can only write to one window/remote
		at a time).
	config.h encourages you to redefine rand to something better
		on your system
	Archive now separated into directories
	Interpreter should run significantly faster
	Primitives that previously displayed messages (connect(),
		regcomp()) on error now set errmsg builtin instead.
		Likewise, error messages caused by send and receive
		errors now show up in errmsg builtin.  parse() still
		displays error messages.
	Property lists: new_assoc() creates a new type; alloc(size, 
		assoc) creates a plist of that type.  plist->elem
		retrieves an element.  See documentation for details.
	Distribution:
		Most things completely rewritten, notably the trigger
		system and command parser.  A number of things noted
		as removed above are now handled in the distribution.
		See the docs for information.  Also, includes new
		utility routines for VTC programming.
