"--help" is an almost universally recognised command-line argument for
displaying a program's usage
information. However, it is ignored by zprod-manager. Usage information is only
available when no
command-line arguments are supplied, which is counter-intuitive.
Reproducible: Always
Steps to Reproduce:
1. zprod-manager --help
Actual Results:
zprod-manager launches in interactive mode.
Expected Results:
zprod-manager should display the same help/usage text as when zprog-manager is
run without any
command-line arguments.

patch to add primitive "--help" support
With the patch applied, zprod-manager will dispay the help/usage text when run
with any number of command-line arguments, provided the last one is "--help".
This is better than the simple solution of requiring that "--help" be the only
command-line argument, as it allows for people trying to get help on particular
operations by typing "zprod-manager add --help".
The patch doesn't catch situations where additional arguments follow "--help",
nor does it check for "-h" etc, but I believe it's a simple patch that
addresses the most common situations and is the best solution short of
rewriting to use getopt.
