CVS
You must be a SLAC GLAST developer to check out the source code from CVS. Here is an example of checking out all of grits:
$ export CVS_RSH=ssh $ cvs -d :ext:langston@centaurusa.slac.stanford.edu:/nfs/slac/g/glast/ground/cvs co grits
The grits CVS module contains all of the third party jar files necessary to build and run the grits webapp. However, you will still need to have a few other third party tools installed before you will be able to build and run grits, which is covered in the 3.2 Toolset section.
