<language> A language compatible with the language
	{Dylan}(TM).  Thomas is NOT {Dylan}(TM).

	The first public release of a translator to {Scheme} by Matt
	Birkholz, Jim Miller, and Ron Weiss, written at {Digital
	Equipment Corporation}'s {Cambridge Research Laboratory} runs
	(slowly) on {MIT}'s {CScheme}, DEC's {Scheme->C}, Marc
	Feeley's {Gambi}, {Macintosh}, {PC}, {Vax}, {MIPS}, {Alpha},
	{680x0}.

<programming> One of a sequence of copies of a program, each
	incorporating new modifications.  Each version is usually
	identified by a number, commonly of the form X.Y where X is
	the major version number and Y is the release number.
	Typically an increment in X (with Y reset to zero) signifies a
	substantial increase in the function of the program or a
	partial or total re-implementation, whereas Y increases each
	time the progam is changed in any way and re-released.

	Version numbers are useful so that the user can know if the
	program has changed ({bugs} have been fixed or new functions
	added) since he obtained his copy and the programmer can tell
	if a bug report relates to the current version.  It is thus
	always important to state the version when reporting bugs.
	Statements about compatibility between different software
	components should always say which versions they apply to.

	See {change management}.
