Programs in this directory were submitted by the Space Science Division
of the Naval Research Laboratory.

1.0 MECHANIC -  This detached process lowers the priority of interactive
		processes which accumulate mass quantities of CPU time.
		It is intended to persecute users who run compute bound
		jobs interactively, rather than submitting them as batch
		jobs.

		The way we use it, it executes every 5 minutes and lowers
		the priority to 3 after 10 minutes of CPU time have been
		accumulated, and to 2 after 20 minutes of CPU time.
		Processes with a SYSTEM UIC are not attacked.
		The execution frequency can be changed by modifying
		MECHANIC.COM and the CPU time thresholds and priorities
		can be changed by modifying MECHANIC.FOR.

		To install the MECHANIC, copy MECHANIC.COM and MECHANIC.EXE
		to some directory which has the logical name LOGICAL, for
		instance, and then change the command in MECHANIC.COM which
		runs the MECHANIC to: $ RUN LOGICAL:MECHANIC.EXE. Then,
		put the following command in SYS$MANAGER:SYSTARTUP.COM:
		$ @LOGICAL:MECHANIC.COM

2.0 FINDUIC -	This is a modified version of a program originally written
		by Tim Miles of TRIUMF and submitted under [VAX81B.FINDUIC].
		FINDUIC searches a disk for all files owned by a specified
		UIC. This version provides a 2 column output which is sorted
		by file specification: fully qualified file specification;
		and file size. It calls the subroutine FSPEC, which is
		included.

		To install FINDUIC, copy FINDUIC.EXE to SYS$SYSTEM, for
		instance, and define a global symbol similiar to:
		$ FIND*UIC == "$SYS$SYSTEM:FINDUIC"

		To use FINDUIC:
		$ FIND DRA1:[g,m]/OUTPUT=ALLFILES.LIS	!for example
		If [g,m] is not specified, the current uic is used.
		If /OUTPUT is not specified, output is to SYS$OUTPUT

3.0 BIGFILES -	This program is a modified version of FINDUIC which searches
		for the 50 largest files on a disk. The parameter, 50, can be
		changed by changing a parameter statement in BIGFILES.MAR.
		BIGFILES provides a 3 column output which is sorted in
		descending order of file size: file size; owner uic; and
		fully qualified file specification. It calls the subroutine
		FSPEC, which is included.

		To install BIGFILES, copy BIGFILES.EXE to SYS$SYSTEM, for
		instance, and define a global symbol similiar to:
		$ BIG*FILES == "$SYS$SYSTEM:BIGFILES"

		To use BIGFILES:
		$ BIG DRA1:/OUTPUT=DRA1BIG.LIS		!for example
		If /OUTPUT is not specified, output is to SYS$OUTPUT

4.0 FID2FSPEC -	This is a DCL command procedure used to convert a File
		ID (FID) to a fully qualified file specification. It
		runs the image TFID2FSPC, which calls the subroutine
		FID2FSPEC, which calls the subroutine FSPEC. TFID2FSPC
		and the subroutines are all included.

		To install FID2FSPEC, copy FID2FSPEC.COM and TFID2FSPC.EXE
		to some directory which has the logical name LOGICAL, for
		instance, and then modify the command in FID2FSPEC.COM which
		runs TFID2FSPC to: $ RUN LOGICAL:TFID2FSP
		Define a global symbol similiar to:
		$ FID*2FSPEC == "@LOGICAL:FID2FSPEC"

		To use FID2FSPEC:
		$ FID DRA1: (514,92,0)			!for example
		The corresponding file specification is output to SYS$OUTPUT.
