Usage: #{opt.program_name} [options] [names...]

Where name can be:

  Class | Class::method | Class#method | Class.method | method

All class names may be abbreviated to their minimum unambiguous form. If a name
is ambiguous, all valid options will be listed.

The form '.' method matches either class or instance methods, while #method
matches only instance and ::method matches only class methods.

For example:

    #{opt.program_name} Fil
    #{opt.program_name} File
    #{opt.program_name} File.new
    #{opt.program_name} zip

Note that shell quoting may be required for method names containing
punctuation:

    #{opt.program_name} 'Array.[]'
    #{opt.program_name} compact\\!

By default ri searches for documentation in the following directories:

    #{directories.join "\n    "}

Specifying the --system, --site, --home, --gems or --doc-dir options will
limit ri to searching only the specified directories.

Options may also be set in the 'RI' environment variable.
