Excellent. I've actually heard of strace before, but haven't taken the
time to build it. I'll have to give that a try.
For the most part, I've pretty much got the base data I needed from
deconstructing the kernel syscall source code and performing a hell of a
lot of trial and error.
I'm going to refine the data to a wider range of readability and make it
available for folk in similar positions.
