David, Thanks for adding a test for _tkinter.c. It's a really good start. Unfortunately, testPackageRequire() fails for me because I don't have Tclx. Is there any way to make the test more robust? I also have a question about the implementation. It looks like useTK is required to be an integer. Is that correct? I would have expected to be able to use any boolean value.

Update of /cvsroot/python/python/dist/src/Lib/lib-tk In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv24617/dist/src/Lib/lib-tk
Modified Files: Tkinter.py Log Message: Implementation of patch 869468
Allow the user to create Tkinter.Tcl objects which are just like Tkinter.Tk objects except that they do not initialize Tk. This is useful in circumstances where the script is being run on machines that do not have an X server running -- in those cases, Tk initialization fails, even if no window is ever created.
Includes documentation change and tests.
Tested on Linux, Solaris and Windows.
