-# Warning: When you start emacs with tk emacs/python can sometimes hang

-# 1) start the show
-# 2) try interacting with python (enter some number for example)

+
+Features:
+   -  Right mouse button over a state pops up a menu allowing you to
+	request a transition to that state
+   -  Middle mouse button will grab the canvas and slide things around
+	if your state machine is bigger than the viewing area
+   -  There are some self explanatory menu options up at the top, the most
+	useful being: "print FSM layout" which will print out python code
+	which will create an FSM augmented with layout information for the
+	viewer so everything shows up in the same place the next time you
+	inspect the state machine
+
+CAVEAT:
+
+There is some unexplained problems with using TK and emacs right now which
+occasionally results in everything locking up.  This procedure seems to
+avoid the problem for me:
+
+# Start up the show
+from ShowBaseGlobal import *
+
+# You will see the window and a Tk panel pop open
+
+# Type a number at the emacs prompt
+>>> 123
+
+# At this point everything will lock up and you won't get your prompt back
+
+# Hit a bunch of Control-C's in rapid succession, in most cases
+# this will break you out of whatever badness you were in and 
+# from that point on everything will behave normally
+
+
 # This is how you pop up an inspector
