Thanks a lot for testing this out.  Your input has been extremely helpful.

This is at the top of my list to fix. I have code to sanity check the input
for this setting - limit option to allowed values - but I haven't set it up.

Easily done, I'll see to it.

I just didn't understand the wording in some of the documentation around
this.  You are probably right.

I'm also considering a couple of other things:

   1. Allow settings to be saved to a config file that is read on startup.
   2. A Read / Execute / Print / Loop  (REPL) mode for more interactive
   testing.  - this may be overkill.
   3. documentation (haha)
