groovydoc's help option is misleading

When you specify the help option to groovydoc

groovydoc -help

It sounds like by default only protected and public fields and methods are included in the documentation.

-protected Show protected/public classes and members (default)

But this is not true as it generates documentation for public, protected, and package classes and members. This what the package option does:

-package Show package/protected/public classes and members

I kind of think that both options should be removed and that there should be a statement below how to use the groovydoc tool that documents the default behavior.

usage: groovydoc [options] [packagenames] [sourcefiles]

By default, groovydoc generates documentation for public/protected/package classes and members.

...

Another issue is the public option which explicitly states that it only generates documentation for public classes and members.

-public Show only public classes and members

This is not true either as it generates documentation for both public and package classes and members.
