# url dsl -- the ultimate url dsl!
#
# You just can't beat this:
#
# $ irb -r url_dsl
# >> include URLDSL
# => Object
# >> http://github.com/defunkt.json
# => #<URLDSL::Request http://github.com/defunkt.json/>
# >> puts http://github.com/defunkt.json
# [{"repository":{"url":"http://github.com/defunkt/repl",
# ... etc ...
# => nil
#
# Or this:
#
# >> require 'json'
# => true
# >> url = http://twitter.com/statuses/show/6592721580.json
# => #<URLDSL::Request http://twitter.com/statuses/show/6592721580.json/>
# >> JSON.parse(url.to_s)['text']
# => "He nose the truth."
#

# URLDSL do
# puts http://twitter.com/brosner/status/6592721580.json
