Thanks William, I'm afraid we need the programs to be sent to the
shootout, we can't skim them from other places.

Some folk just post them on the mailing list:
http://shootout.alioth.debian.org/miscfile.php?sort=fullcpu&file=mailinglist&title=mailing%20list

others use the message form or email them to igouy2

best wishes, Isaac
