simulavr.tcl should be using tclsh not wish.  tclsh shouldn't
be doing that I would think.

I want to add similar support for the analogs and eventually
a part of 8 channel ADC modules on the SPI.  All would be drive
by this test framework.  But baby steps.

I was beginning to realize that.  I also have a set of questions
like "what are you doing with X?" for them.  I was brought on
to help with the testing and had nothing to do (for once) with
the application design/development.

Yes.  I was just using this to have some IO for the test
that didn't get in the way of using the real devices.

I am really hoping this works out to be a great contribution.
