George Peter Staplin: Whim has historically and at present been a part of megapkg. Megapkg is a tree of extensions, and a variety of Tcl code. The Tcler's Wiki covers some of the other extensions.
The primary megapkg extensions that Whim depends on (without applets) are:
- pwm.so provides commands for extending Tcl/Tk to allow for writing window managers. Note: it has no relation to the TKWM code.
- sys.so provides sys:exec for a non-forking exec, pipe creation, and various other little things.
