"--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.

Created attachment 74469 [details, diff] 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.
Fixed in app-admin/zprod-manager-0.3.1
