+/* Here's some JavaScript software for implementing OAuth.
+
+   This isn't as useful as you might hope.  OAuth is based around
+   allowing tools and websites to talk to each other.  However,
+   JavaScript running in web browsers is hampered by security
+   restrictions that prevent code running on one website from
+   accessing data stored or served on another.
+
+   Before you start hacking, make sure you understand the limitations
+   posed by cross-domain XMLHttpRequest.
+
+   On the bright side, some platforms use JavaScript as their
+   language, but enable the programmer to access other web sites.
+   Examples include Google Gadgets, and Microsoft Vista Sidebar.
+   For those platforms, this library should come in handy.
+*/
+
+// The HMAC-SHA1 signature method calls b64_hmac_sha1, defined by
+// http://pajhome.org.uk/crypt/md5/sha1.js
+
+/* An OAuth message is represented as an object like this:
+   {method: "GET", action: "http://server.com/path", parameters: ...}
+
+   The parameters may be either a map {name: value, name2: value2}
+   or an Array of name-value pairs [[name, value], [name2, value2]].
+   The latter representation is more powerful: it supports parameters
+   in a specific sequence, or several parameters with the same name;
+   for example [["a", 1], ["b", 2], ["a", 3]].
+
+   Parameter names and values are NOT percent-encoded in an object.
+   They must be encoded before transmission and decoded after reception.
+   For example, this message object:
+   {method: "GET", action: "http://server/path", parameters: {p: "x y"}}
+   ... can be transmitted as an HTTP request that begins:
+   GET /path?p=x%20y HTTP/1.0
+   (This isn't a valid OAuth request, since it lacks a signature etc.)
+   Note that the object "x y" is transmitted as x%20y.  To encode
+   parameters, you can call OAuth.addToURL, OAuth.formEncode or
+   OAuth.getAuthorization.
+
+   This message object model harmonizes with the browser object model for
+   input elements of an form, whose value property isn't percent encoded.
+   The browser encodes each value before transmitting it. For example,
+   see consumer.setInputs in example/consumer.js.
