=for category Creating and Configuring Widgets
Using this modules causes Tk's Option code to be replaced by versions
which use routines from <X11/Xresource.h> - i.e. same ones every other

and makes it easier to have a single ~/.Xdefaults file which gives sensible
results for both Tk and (say) Motif applications.
Currently B<optionAdd>(I<key> =E<gt> I<value>?, I<priority>?) ignores optional
priority completely and just does XrmPutStringResource().
Perhaps it should be more subtle and do XrmMergeDatabases() or
