Edit: ParenMatch.py

"""ParenMatch -- An IDLE extension for parenthesis matching.

When you hit a right paren, the cursor should move briefly to the left
paren.  Paren here is used generically; the matching applies to
parentheses, square brackets, and curly braces.

    """Highlight matching parentheses

There are three supported style of paren matching, based loosely
    on the Emacs options.  The style is select based on the
    HILITE_STYLE attribute; it can be changed used the set_style
    method.

The supported styles are:

default -- When a right paren is typed, highlight the matching
        left paren for 1/2 sec.

expression -- When a right paren is typed, highlight the entire
        expression from the left paren to the right paren.

TODO:
        - extend IDLE with configuration dialog to change options
        - implement rest of Emacs highlight styles (see below)
        - print mismatch warning in IDLE status window

Note: In Emacs, there are several styles of highlight where the
    matching paren is highlighted whenever the cursor is immediately
    to the right of a right paren.  I don't know how to do that in Tk,
    so I haven't bothered.
