          +  The SBGrid installation client will install the software tree to /opt/sbgrid and create a symlink from this directory to /programs. While admin privileges are not required to run the application, you will need admin privileges to create /opt/sbgrid and /programs. The install client currently relies on 'sudo' for these tasks and should in installed from an account with sudo privileges. While not strictly required, we recommend a dedicated 'sbgrid' user account for software management. This ensures the software can't be modified by user accounts and that data won't be mistakenly saved into the software stack and possibly inadvertantly deleted by software updates. 

           **Existing SBGrid installations must be renamed or removed.**

             If you have previously installed SBGrid software on your computer at /programs or at /opt/sbgrid, these directories should be removed or renamed. The client will create these on first run.
