+<p><strong>Relative module names inside define()</strong>: For require("./relative/name") calls that can happen inside a define() function call, be sure to ask for "require" as a dependency, so that the relative name is resolved correctly:</p>

+<pre><code>define(["require", "./relative/name"], function(require) {

+<p>Or better yet, use the shortened syntax that is available for use with <a href="commonjs.html">translating CommonJS</a> modules:</p>
+
+<pre><code>define(function(require) {
+    var mod = require("./relative/name");
+});
+</code></pre>
+
+<p>This form will use Function.prototype.toString() to find the require() calls, and add them to the dependency array, along with "require", so the code will work correctly with relative paths.</p>
