NAME

       ri1.9.1 - Ruby Information at your fingertips

SYNOPSIS

       ri1.9.1 [options] [names...]

DESCRIPTION

       ri1.9.1  displaies  information on Ruby classes, modules, and methods.  You can give the names of classes
       or methods to see their documentation.  Partial names may be given: if the  names  match  more  than  one
       entity, a list will be shown, otherwise details on that entity will be displayed.

       Nested  classes  and  modules can be specified using the normal Name::Name notation, and instance methods
       can be distinguished from class methods using "." (or "#") instead of "::".

       For example:
           ri1.9.1 File
           ri1.9.1 File.new
           ri1.9.1 F.n
           ri1.9.1 zip

       Note that shell quoting may be required for method names containing punctuation:
           ri1.9.1 'Array.[]'
           ri1.9.1 compact\!
