+ *
+ * Option names may be given in "dot notation" which allows to reference

+ * dot is specified, it refers to an option within the same configuration
+ * section. If specified as <code>configname.sectionid.optionname</code>,
+ * options anywhere within the same form may be specified.
+ *
+ * The object notation also allows for a number of special keys which are

+ * constraint evaluation. The associated value of these special "tag" keys
+ * is ignored. The recognized tags are:
+ *
+ * <ul>
+ * <li>
+ * <code>!reverse</code><br>
+ * Invert the dependency, instead of requiring another option to be
+ * equal to the dependency value, that option should <em>not</em> be
+ * equal.
+ * </li>
+ * <li>
+ * <code>!contains</code><br>
+ * Instead of requiring an exact match, the dependency is considered
+ * satisfied when the dependency value is contained within the option
+ * value.
+ * </li>
+ * <li>
+ * <code>!default</code><br>
+ * The dependency is always satisfied
+ * </li>
+ * </ul>

+ * <code>opt.depends("foo", "test")</code><br>

+ * The LuCI form class provides high level abstractions for creating creating
+ * UCI- or JSON backed configurations forms.
+ *
+ * To import the class in views, use `'require form'`, to import it in
+ * external JavaScript, use `L.require("form").then(...)`.
+ *
+ * A typical form is created by first constructing a
+ * {@link LuCI.form.Map} or {@link LuCI.form.JSONMap} instance using `new` and
+ * by subsequently adding sections and options to it. Finally
+ * [render()]{@link LuCI.form.Map#render} is invoked on the instance to
+ * assemble the HTML markup and insert it into the DOM.
+ *
+ * Example:
+ *
+ * <pre>
+ * 'use strict';
+ * 'require form';
+ *
+ * var m, s, o;
+ *
+ * m = new form.Map('example', 'Example form',
+ * 'This is an example form mapping the contents of /etc/config/example');
+ *
+ * s = m.section(form.NamedSection, 'first_section', 'example', 'The first section',
+ * 'This sections maps "config example first_section" of /etc/config/example');
+ *
+ * o = s.option(form.Flag, 'some_bool', 'A checkbox option');
+ *
+ * o = s.option(form.ListValue, 'some_choice', 'A select element');
+ * o.value('choice1', 'The first choice');
+ * o.value('choice2', 'The second choice');
+ *
+ * m.render().then(function(node) {
+ * document.body.appendChild(node);
+ * });
