BOCA is an websystem written in PHP to manage a competition with format similar to the ACM ICPC. Latam BOCA Linux is just a hard-disk image of a linux distribution (Ubuntu) with the usual packages that are needed to run a competition, both for the server and client computers (teams, judges, etc).
*** Bruno Ribas has created some ubuntu/debian apt-get style packages for building the system. They are the easiest way to have all done. Please check that at github and at boca-users list.
