To develop or modify any beamline code, the easiest way is to work
on clas10, and setup the epics environment, by typing
source /apps/epics/setup/setup_epics. This should configure
default EPICS path and default CVS directories.
CVS is a program designed for code management that we are using
for EPICS in Hall B. Once the $CVSROOT directory is set to the right area (the setup_epics program does it),
any beamline application can be retrieved through CVS. I will write
the right command to type for each application I will detail below.
