Rather than getting Configuration options from the user manual, it
might be better to have a consolidated location and standard format
for specifying the Configuration options, including default values and
acceptable values/ranges (for options where ranges make sense). Right
now, confdefs.h is the only definitive location for Configuration
parameters and is the place to go to learn how a Configuration
parameter is actually used.

It should best work on any reasonable flavor of Linux, and on Windows and Mac.

TkInter might be a good place to start, but the design of the
Configuration tool should not be bound so tightly to the GUI that
replacing the GUI would be hard. Thus, we can consider other GUI tools
and evaluate them at an early stage to determine which ones will
suffice. A nice list of possibilities is at:

I would discuss them once the baseline becomes clear. Please help me analyse any deficiencies in my understanding.
