If the directory specified by buildLocation exists, it is removed and recreated to provide a clean checkout. After that, each subpackage of the build is checked out individually into the buildLocation directory. All output from the program is stored in the entry database table. If the checkout takes longer than 60 minutes, it is aborted and generates an error. If there is a problem with the checkout process, an e-mail is sent to the relmanlist@glast2.stanford.edu mailing list.
