Yes. In fact, I've been slowly changing the code to allow dynamically
pluggable widget extensions. The first library would be the core set
for Tcl/Tk. I was planning on making the second Tix.
I haven't documented the process yet, but it involved creating a
file in the VT heirarchy "lib/lib_<module>" which will be detected
and loaded at run-time. Look at the structure of lib_core and see
if that makes any sense.
I'm open to ideas.
