[Clas_slow_control] How to switch EPICS versions on clon cluster

[nerses at jlab.org]

Dear Slow Controllers,

after upgrade of clon02, I've changed also how the EPICS environment is
set up.

Before, on clon02 by default the old EPICS will load, and new one elsewhere.
Now, by default the new EPICS environment will set up. In order if someone
wants to have the old one then the command/alias is available:

setup_epics_R3.13.4

which will set up the environment accordingly.
This works for both epics and clasrun accounts.
If You want to have same configuration in Your user account, then I'll
recommend to copy the lines from ~epics/.login file.

------------------------------------------
#
# EPICS
# By default we will setup the new epics.
# If one wants the old one, then should use the following alias.
#
alias setup_epics_R3.13.4 "source
/home/epics/R3.13.4/epicsB/prod/scripts/setup_epics prod R3.13.4"
setenv CLAS /usr/local/clas/devel
setenv OSTYPE `uname`
setenv MACHINE `uname -m`
source $CLAS/R3.14.8.2/.setup
------------------------------------------
