The code for the system tests currently resides in /nfs/farm/g/glast/u17/systests/src. (TBD: commit the current working version of the code to CVS!)
The system test area, $SYSTESTS, is owned by glastsys and the tests are run via this account (most necessary environment variables are set up in the scripts. The password for this account is kept in escrow and should be kept up-to-date there. See the confluence page on escrow here for details.
NB: if you have logged in as glastsys, which you need to do to get write-access, the envvar $SYSTESTS is set to /nfs/farm/g/glast/u16u17/systests. Also, you need to login to a SLAC linux machine; practically speaking, this means a noric. This is because the output directory is named with the operating system of the machine that submits the batch jobs, and the batch job looks for the name if its operating system. (This probably isn't necessary, since that directory contains platform-independent files.)
