On a Mac or Linux machine that is configured for running CT3 experiments (Java and Ant, etc., are properly set up), download the two attached scripts.

1. Running ./ct3-checkout.sh will do a Subversion checkout of the full CT3 source tree, into a directory called ct3repos in your user folder (~/ct3repos).
2. Running ./ct3-update.sh will update the full source tree from Subversion, and then run the Ant build scripts for the trunk and every branch.
   You can also run ./ct3-update.sh trunk to update just the trunk, or ./ct3-update.sh myBranch to update just the branch called myBranch.
