 # UCBLogo
-Berkeley Logo interpreter
 
-This is a free (both senses) interpreter for the Logo programming language.
-
-The current version is 6.0 if you're running wxWidgets, 5.4 if not.  (They are made from the same source code.)
-
-The distribution also includes version 5.3 for frozen platforms DOS and Mac Classic (pre-OS X).
+## Berkeley Logo interpreter
 
-I have become super busy doing other things (snap.berkeley.edu, bjc.edc.org) and so no development has happened on UCBLogo (a/k/a Berkeley Logo) in a decade or so.  I would love for someone to take it over, and would even help you get started.  (You'll need help because of the incredible chain of kludges herein.)
-
-There is a 95% finished (but you know what that means) implementation of OOP in the style of Object Logo.
-
-It would be especially great if the someone who takes it over knows how to make an interpreter run fast.  /This/ interpreter is more or less the one from SICP 5.4 (the Explicit Control Evaluator) but with kludges added, mainly because not all Logo procedures return values.
+This is a free (both senses) interpreter for the Logo programming language.
 
-There's one piece of good news:  There's a Program Logic Manual in source/plm.  So all the things I've forgotten aren't lost forever.  :-)
+The interpreter was written primarily by Daniel Van Blerkom, Brian Harvey,
+Michael Katz, Douglas Orleans and Joshua Cogliati. Thanks to Fred Gilham for the X11 code.
