Thanks for also trying it, Steffan. I am glad to hear you think it is
worth including in the repo.

I doubt that changes which break this tool will occur with any great
frequency. Even so I think an automated test suite is a necessity.

gdb does provide support for scripting automatic tests of debugger
functionality. I'll look into this to see if I can find some way of
automatically testing at least the basic functionality. However, I think
I'm probably going to need some help from the build team shoe-horning
any such tests into the build system.
