I believe Aggelos was looking at freebsd compatibility and c was his most
comfortable language. Since programming such a thing in c was way beyond my
capabilities and Aggelos had already taken on the task I was very happy to
use this as the new codebase. The previous BASH one was getting flakier the
more I tried to add to it. Also there were subtle things happening in the
BASH version that made for much more variation in results than this version.
So it's as much coincidence that Aggelos was writing a new version and I was
looking for someone to write one that this codebase was chosen for it.

Possibly but clearly c has no major limitations once the hard part (the
wrapper for the other applications) has been done.

I don't know. Anything that may taint the results is bad but I have no idea
how many confounding variables this really introduces. I need feedback from
the developers that look at these results to know whether this is worthwhile
or not. While I'm the said maintainer, contest has grown into a beast of it's
