Tclkit

From http://www.equi4.com/tclkit:

License - Tclkit is a combination of Tcl, Tk, IncrTcl, TclVFS, Zlib, and
Metakit. Metakit is open source, using an X/MIT-style license [14].
Tcl/Tk, IncrTcl, TclVFS, and Zlib have their own, BSD-ish open source
licenses, so in my understanding this code can be used freely, also
commercially.
