#	It is expressly permitted to make a copy of this file in some
#	other directory than $GEMSTONE/sys; hence help logic

	monName		    - name of shared page cache monitor
	numPages	    - number of memory pages for monitor
	numProcs	    - number of process slots for monitor
	memLock		    - true if monitor's memory should be locked in place
	spinLockCount	    - spin count for shared locks
	protocol	    - network protocol for connection, such as \"TCP\"
	wellknown	    - bound network address, such as a TCP/IP port number
	timeout		    - how long, in seconds, to wait for connection
        targetFreeFrames    - target free frame limit for the cache
        numFreeFrameServers - number of free frame page servers to start
        numSharedCounters   - number of shared counters to create
        serverNum           - number of this free frame page server, zero based
        numServers          - total number of free frame page servers started

This Bourne shell script is invoked by a netldi in reponse to a
request of the netldi to provide GemStone database file I/O. By
default, netldi uses the file $GEMSTONE/bin/services.dat to translate the
name runpgsvrmain to a command that executes this script.  If no such
translation is found, the command \$HOME/runpgsvrmain is executed by
netldi instead.
