Using starkits for extensions is also quite simple, but you'll need to
implement a few things yourself: you'll have write some code to load
the startkit package in tcl (see LTK:*INIT-WISH-HOOK*), create a
binding in ltk for loading the kits themselves (and any code in them),
and you'll probably want one for loading dll-based libs (some
extensions like TWAPI don't have starkits readily available).
Thanks Matt I appreciate the tip. Do you find that you make use of
extensions related to Tk, or related to Tcl instead?
