I'm going to suggest for the good of all humanity, that the person who 
is judging a comp.sci challenge should probably be able to script up an 
automated testing harness such that you can do something like

for f in *.zip; do ./run_test.sh $f; done

At the high level (say submissions are zip files or whatever) and then 
your shell script unpacks, tries to compile, run, compares, etc.

Just saying...
