            Simulated Photon Source Shutter Simulator
            =========================================

    The files in this directory provide a simulator for training in
    EPICS CA client programming. Instructions for students can be
    found in the file instructions.txt and their initial template file
    is template.pl.

    To run the simulator, edit the start-ioc.cmd script and set the
    path in the initial #! line (the example given should work on
    most APS Linux workstations), then just execute that file once
    Students should *not* run this themselves, one IOC provides the
    PVs for all students to use.

    An MEDM screen SPS-shutters.adl is provided to show the current
    state of all the shutters and allow the instructor to enable and
    disable the shutter-permit for the SPS.
