+<h1>osc-min</h1>
+
+<p><em>simple utilities for open sound control in node.js</em></p>
+
+<p>This package provides some node.js utilities for working with 
+<a href="http://opensoundcontrol.org/">OSC</a>, a format for sound and systems control. <br />
+Here we implement the <a href="http://opensoundcontrol.org/spec-1_1">OSC 1.1</a> specification.  OSC is a transport-independent
+protocol, so we don't provide any server objects, as you should be able to 
+use OSC over any transport you like.  The most common is probably udp, but tcp
+is not unheard of.</p>
+
+<hr />
+
+<h2>Installation</h2>
+
+<p>The easiest way to get osc-min is through <a href="http://npmjs.org">NPM</a>.
+After install npm, you can install osc-min in the current directory with</p>
+
+<p><code>
+npm install osc-min
+</code></p>
+
+<p>If you'd rather get osc-min through github (for example, if you're forking
+it), you still need npm to install dependencies, which you can do with</p>
+
+<p><code>
+npm install --dev
+</code></p>
+
+<p>Once you've got all the dependencies you should be able to run the unit
+tests with </p>
+
+<p><code>
+npm test
+npm run-script coverage
+</code></p>
+
+<hr />
+
+<h2>Examples</h2>
+
+<h3>A simple OSC printer;</h3>
+
+<pre><code>    sock = udp.createSocket("udp4", function(msg, rinfo) {
+      try {
+        return console.log(osc.fromBuffer(msg));
+      } catch (error) {
+        return console.log("invalid OSC packet");
+      }
+    });
+
+    sock.bind(inport);
+</code></pre>
+
+<h3>Send a bunch of args every two seconds;</h3>
+
+<pre><code>    sendHeartbeat = function() {
+      var buf;
+      buf = osc.toBuffer({
+        address: "/heartbeat",
+        args: [
+          12, "sttttring", new Buffer("beat"), {
+            type: "integer",
+            value: 7
+          }
+        ]
+      });
+      return udp.send(buf, 0, buf.length, outport, "localhost");
+    };
+
+    setInterval(sendHeartbeat, 2000);
+</code></pre>
+
+<h3>A simple OSC redirecter;</h3>
+
+<pre><code>    sock = udp.createSocket("udp4", function(msg, rinfo) {
+      var redirected;
+      try {
+        redirected = osc.applyAddressTransform(msg, function(address) {
+          return "/redirect" + address;
+        });
+        return sock.send(redirected, 0, redirected.length, outport, "localhost");
+      } catch (error) {
+        return console.log("error redirecting: " + error);
+      }
+    });
+
+    sock.bind(inport);
+</code></pre>

+
+<h2>Exported functions</h2>
+
+<hr />
+
+<h3>.fromBuffer(buffer, [strict])</h3>
+
+<p>takes a node.js Buffer of a complete <em>OSC Packet</em> and 
+outputs the javascript representation, or throws if the buffer is ill-formed.</p>
+
+<p><code>strict</code> is an optional parameter that makes the function fail more often.</p>
+
+<hr />
+
+<h3>.toBuffer(object, [strict])</h3>
+
+<p>takes a <em>OSC packet</em> javascript representation as defined below and returns
+a node.js Buffer, or throws if the representation is ill-formed.</p>
+
+<hr />
+
+<h3>.toBuffer(address, args[], [strict])</h3>
+
+<p>alternative syntax for above.  Assumes this is an <em>OSC Message</em> as defined below, 
+and <code>args</code> is an array of <em>OSC Arguments</em> or single <em>OSC Argument</em></p>
+
+<hr />
+
+<h3>.applyAddressTransform(buffer, transform)</h3>
+
+<p>takes a callback that takes a string and outputs a string,
+and applies that to the address of the message encoded in the buffer,
+and outputs an encoded buffer.</p>
+
+<p>If the buffer encodes an <em>OSC Bundle</em>, this applies the function to each address 
+in the bundle.</p>
+
+<p>There's two subtle reasons you'd want to use this function rather than 
+composing <code>fromBuffer</code> and <code>toBuffer</code>:
+  - Future-proofing - if the OSC message uses an argument typecode that
+    we don't understand, calling <code>fromBuffer</code> will throw.  The only time
+    when <code>applyAddressTranform</code> might fail is if the address is malformed.
+  - Accuracy - javascript represents numbers as 64-bit floats, so some
+    OSC types will not be able to be represented accurately.  If accuracy
+    is important to you, then, you should never convert the OSC message to a
+    javascript representation.</p>
+
+<hr />
+
+<h3>.applyMessageTransform(buffer, transform)</h3>
+
+<p>takes a function that takes and returns a javascript <em>OSC Message</em> representation,
+and applies that to each message encoded in the buffer,
+and outputs a new buffer with the new address.</p>
+
+<p>If the buffer encodes an osc-bundle, this applies the function to each message 
+in the bundle.</p>
+
+<p>See notes above for applyAddressTransform for why you might want to use this.
+While this does parse and re-pack the messages, the bundle timetags are left
+in their accurate and prestine state.</p>
+
+<hr />
+
+<h2>Javascript representations of the OSC types.</h2>
+
+<p>See the <a href="http://opensoundcontrol.org/spec-1_0">spec</a> for more information on the OSC types.</p>
+
+<ul>
+<li><p>An <em>OSC Packet</em> is an <em>OSC Message</em> or an <em>OSC Bundle</em>.</p></li>
+<li><p>An <em>OSC Message</em>:</p>
+
+<pre><code>  {
+      oscType : "message"
+      address : "/address/pattern/might/have/wildcards"
+      args : [arg1,arg2]
+  }
+</code></pre>
+
+<p>Where args is an array of <em>OSC Arguments</em>.  <code>oscType</code> is optional.
+<code>args</code> can be a single element.</p></li>
+<li><p>An <em>OSC Argument</em> is represented as a javascript object with the following layout:</p>
+
+<pre><code>  {
+      type : "string"
+      value : "value"
+  }
+</code></pre>
+
+<p>Where the <code>type</code> is one of the following:</p>
+
+<ul><li><code>string</code> - string value</li>
+<li><code>float</code> - numeric value</li>
+<li><code>integer</code> - numeric value</li>
+<li><code>blob</code> - node.js Buffer value</li>
+<li><code>true</code> - value is boolean true</li>
+<li><code>false</code> - value is boolean false</li>
+<li><code>null</code> - no value</li>
+<li><code>bang</code> - no value (this is the <code>I</code> type tag)</li>
+<li><code>timetag</code> - numeric value</li></ul>
+
+<p>Note that <code>type</code> is always a string - i.e. <code>"true"</code> rather than <code>true</code>.</p>
+
+<p>The following non-standard types are also supported:</p>
+
+<ul><li><code>double</code> - numeric value (encodes to a float64 value)</li></ul>
+
+<p>For messages sent to the <code>toBuffer</code> function, <code>type</code> is optional.
+If the argument is not an object, it will be interpreted as either
+<code>string</code>, <code>float</code>, or <code>blob</code>, depending on its javascript type.</p></li>
+<li><p>An <em>OSC Bundle</em> is represented as a javascript object with the following layout</p>
+
+<pre><code>  {
+      oscType : "bundle"
+      timetag : 7
+      elements : [element1, element]
+  }
+</code></pre>
+
+<p>Where the timetag is a javascript-native numeric value of the timetag,
+and elements is an array of either an <em>OSC Bundle</em> or an <em>OSC Message</em>
+The <code>oscType</code> field is optional, but is always returned by api functions.</p></li>
