-      :doc "Agent-based asynchronous HTTP client.
-
-  This is a HTTP client library based on Java's HttpURLConnection
-  class and Clojure's Agent system.  It allows you to make multiple
-  HTTP requests in parallel.
-
-  Start an HTTP request with the 'http-agent' function, which
-  immediately returns a Clojure Agent.  You will never deref this
-  agent; that is handled by the accessor functions.  The agent will
-  execute the HTTP request on a separate thread.
-
-  If you pass a :handler function to http-agent, that function will be
-  called as soon as the HTTP response body is ready.  The handler
-  function is called with one argument, the HTTP agent itself.  The
-  handler can read the response body by calling the 'stream' function
-  on the agent.
-
-  The value returned by the handler function becomes part of the state
-  of the agent, and you can retrieve it with the 'result' function.
-  If you call 'result' before the HTTP request has finished, it will
-  block until the handler function returns.
-
-  If you don't provide a handler function, the default handler will
-  buffer the entire response body in memory, which you can retrieve
-  with the 'bytes', 'string', or 'stream' functions.  Like 'result',
-  these functions will block until the HTTP request is completed.
-
-  If you want to check if an HTTP request is finished without
-  blocking, use the 'done?' function.
-
-  A single GET request could be as simple as:
-
-    (string (http-agent \"http://www.stuartsierra.com/\"))
-
-  A simple POST might look like:
-
-    (http-agent \"http...\" :method \"POST\" :body \"foo=1\")
-
-  And you could write the response directly to a file like this:
-
-    (require '[clojure.contrib.io :as d])
-
-    (http-agent \"http...\"
-                :handler (fn [agnt] 
-                           (with-open [w (d/writer \"/tmp/out\")] 
-                             (d/copy (stream agnt) w))))
