DESCRIPTION:
	This script produces HMS jobs reports.

OPTIONS:
 -a	Show all HMS jobs regardless of the state.

 -o	Show only \"Open\" HMS jobs, which includes jobs in these states:
        * open
        * inprogress
        * blocked

	This skips jobs in these states:
	* closed
        * duplicate
        * fixed (optional status to use before closed).
	* punted
        * obsolete
	* suspended

	The '-o' behavior is the default.

 -me	Show only jobs for which the OwnedBy setting is the current user.
	Guessing logic is applied to map the current OS user to a Workshop account,
	e.g. ttyler -> tom_tyler, etc.  This works for some folks.

	See the guess_workshop_user() function in env.sh for details.

	Works with '-a' and '-o'.

 -u <workshop_user>
	Show only jobs for which the OwnedBy setting is the specified Workshop user
	account.

	Specify the special value 'none' to list unassigned jobs, i.e. those for
	which the OwnedBy field is not set.

	Works with '-a' and '-o'.

 -st <status1>[,<status2>,...]
	Specify a comma-delimited list of status values to include.

	The valid values can be seen by doing: p4 jobspec -o

 -v<n>	Set verbosity 1-5 (-v1 = quiet, -v5 = highest).

	The default is -v3.

	Specify -v4 to see the query used with the 'p4 jobs -e' command.

 -L <log>
	Specify the path to report log file, or the special value 'off' to disable
	logging.  By default, all output (stdout and stderr) goes to a file, then
	name of which is displayed when the script starts.

	NOTE: This script is self-logging.  That is, output displayed on the screen
	is simultaneously captured in the log file.  Do not run this script with
	redirection operators like '> log' or '2>&1', and do not use 'tee'.

-si	Operate silently.  All output (stdout and stderr) is redirected to the log
	only; no output appears on the terminal.  This cannot be used with
	'-L off'.
      
 -r	No-Op.  Prints commands instead of running them.

 -d     Set debugging verbosity.

 -D     Set extreme debugging verbosity using bash '-x' mode.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message
 -V	Dispay version info for this script and its libraries.

EXAMPLES:
	Typical usage is with no arguments, to display open jobs:

	$ThisScript

	Show opened jobs assigned to me (based on the \$WORKSHOP_USER shell
	environment setting).

	$ThisScript -me

	Show only items listed as inprogress:

	$ThisScript -st inprogress
