ri


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  documenta-
       tion.   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\!
