+== COMMAND LINE INTERFACE
+
+httparty also includes the executable <tt>httparty</tt> which can be
+used to query web services and examine the resulting output. By default
+it will output the response as a pretty-printed Ruby object (useful for
+grokking the structure of output). This can also be overridden to output
+formatted XML or JSON. Execute <tt>httparty --help</tt> for all the
+options. Below is an example of how easy it is.
+
+  httparty "http://twitter.com/statuses/public_timeline.json" -f json
