Jeremy, those files do not seem to be in the doc directory.
As for supporting the driver, I think I have made the
majority of the substantive changes in the last couple years
(and tracked down and applied any patches I could find) but I
don't really actively work on it.
I think the driver could be substantially cleaned up internally, and if I would look for anything it would be
to implement some of the higher level tcl api we use
in openacs natively in the driver but it's not something I am
likely to do anything about.
