Delta debugger written in myrddin

[Andrew Chambers <andrewchamberss@xxxxxxxxx>]

Hi everyone,

I've written a 'delta debugger' tool in myrddin which is a useful assistant
when trying to
reduce large test cases into smaller ones. See the github/man page for an
example:

https://github.com/andrewchambers/ddmin

I have personally used it for tracking down a memory leak in a server, and
also for minimizing crashes in various compilers into small reproductions.

Regards,
Andrew Chambers
