Simple by key / value rehashing for Ruby MRI
  (c) 2010 Lourens Naudé (methodmissing) and James Tucker (raggi)

  http://github.com/methodmissing/rehash

This library works with Ruby 1.8 and 1.9 and exposes the following API :

  hash = { 'a' => 1, 'b' => 2 }
  hash.rekey!(:upcase)
  hash == { 'A' => 1, 'B' => 2 }

  hash = { 1 => 'a, 2 => 'b' }
  hash.revalue!(:upcase)
  hash == { 1 => 'A', 2 => 'B' }

To run the test suite:

  rake

Work in progress, thanks for watching!
