NOTE: This package is obsoleted by the latest SqueakMap Package Loader.
The SqueakMap Browser is derived from the ordinary Browser class but uses
the top three listviews to traverse the category tree of SqueakMap.
From this browser you can find/install and upgrade SqueakMap packages with just
a few clicks with that little HandMorph of yours. :-)
The SM Package Loader was derived from SqueakMap Browser.
