INTRODUCTION
This application serves as a sample IOC application for the VME-based
MRD-100 and the Machine Status Link (MSL). It provides instructions of
how to extract the sources and build the application for a beamline IOC.

The application was created as described in 'Chapter 2: Getting Started'
from the 'EPICS Input / Output Controller Application Developer Guide.'
It is intended for VxWorks-based IOCs and is compatible with EPICS base
versions 3.14.6 and 3.14.7 and provides a reasonable application departure
point. 

The distribution is archived in tar format and compressed using zip. It can
be downloaded from the BCDA website (internal) or is available upon request.
The intention is for the application to reside at the same level as EPICS
base with the following structure, however it can be extracted to any
structure.

    EPICS/
        base-3.14.6/
        base-3.14.7/
    msl/
        configure/
   	    documentation/
	    iocBoot/
            iocmslApp/
	    mslApp/
            Db/
            op/
            src/


INSTALLATION
Use the below steps to extract and build the application (assuming the
above structure):
   1) cd EPICS
   2) gzip -cd mslApp.tar.gz | tar -xf -
   3) cd msl
   4) Modify EPICS_BASE in ./configure/RELEASE
   5) Modify the MRD-100 settings in ./iocBoot/iocmslApp/st.cmd
   6) Execute make (Linux) or gnumake (Solaris)
   7) Set the IOCs boot parameter startup script to the path of st.cmd
   8) Reboot the IOC
