Sinatra route versioning.rb

# This module allows you to prepend a version prefix to your Sinatra URLs
# Example:
#
# require 'rubygems'
# require 'sinatra/base'
#
# class App < Sinatra::Base
#   register Versioned
#
#   set :version, 'v1'
#   
#   # => GET /v1/hello
#   get '/hello' do
#     'This is a GET for version' + options.version.inspect
#   end
#   
#   # => POST /v1/hello
#   post '/hello' do
#     'This is a POST for version ' + options.version.inspect
#   end
#   
# end
