How to Run the Simulation
-------------------------

1. $ python scripts/sim-exphi-pmac.py

2. $ camonitor ioc23:m1.RRBV | python scripts/update-phi-pos.py 127.0.0.1

3. Load the EPICS simulation into a soft IOC's st.cmd (replacing /devel/exphi
   with the actual location of exphi)

   a. before iocInit:

      cd /devel/exphi
      < src-sim/st-before-iocInit.cmd
      cd "$(TOP)/iocBoot/$(IOC)"

   b. after iocInit:

      cd /devel/exphi
      < src-sim/st-after-iocInit.cmd
      cd "$(TOP)/iocBoot/$(IOC)"

4. Start the soft IOC
