InfoDock is a behemoth add-on by Altrasoft to the already-impressive XEmacs working environment, adding more features and UI enhancements, as well as helps for programmers such as the OO-Browser, which allows one to browse through classes in Smalltalk, Objective-C, Python, CLOS, Eiffel, Java, and C++. Also included is the Hyperbole PIM. Those of you who complain that they can't find a good, free IDE.... stop looking.
