documentation for tk.call interface

[dbr517]

I'm using Python + Tkinter for a small gui . . . there are LOTS of
places inside Tkinter with code like this:

        self.tk.call('tkwait', 'variable', name)

(this particular one is from the IntVar class).

I've searched the Tkinter docs with no success; can someone point me
at the documentation for tk.call?

Thanks!

Dan
