-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.
