Description

There appears to be no generic way to find out information about a given tool. For some tools, passing no arguments works, but not all tools have mandatory arguments.

I suggest that it's a good idea that all tools accept a "--help" flag which would cause them to print usage information. Currently passing an unknown flag such as --help will cause an exception but no useful usage information will be shown.
