= RubySpec

RubySpec (http://rubyspec.org) provides the annotation of the Ruby
implementation in an executable format.  The make task
`update-rubyspec' retrieves the specification and puts it into this
directory.

== Directory structure
 spec
   -- mspec            driver library for executing the specification.
   -- rubyspec
        -- core        specification for core libraries
       |     -- array
       |     -- bignum
       |     -- ...
       |
        -- fixtures    example classes for writing specs
        -- language    specification for Ruby language itself
        -- library     specification for standard libraries
             -- addrev
             -- ...

== How to run

   $ make test-rubyspec
:mspec command

   $ mspec {language|core|library}
   or
   $ mspec spec/path/to/some_spec.rb
