with changed APIs -- it makes much more sense there.
Also add a new feature: if the first character of a menu label is
a '!', it gets a checkbox. Checkboxes are bound to Boolean Tcl variables
that can be accessed through the new getvar/setvar/getrawvar API;
the variable is named after the event to which the menu is bound.
Much has changed -- too much, in fact, to write down.
The big news is that there's a standard way to write IDLE extensions;
see extend.txt. Some sample extensions have been provided, and
some existing code has been converted to extensions. Probably the
biggest new user feature is a new search dialog with more options,
search and replace, and even search in files (grep).
This is exactly as downloaded from my laptop after returning
from the holidays -- it hasn't even been tested on Unix yet.
