+   * Collection of methods that allow declaration and validation of props that are

+   *
+   *   var Props = require('ReactPropTypes');
+   *   var MyArticle = React.createClass({
+   *     propTypes: {
+   *       // An optional string prop named "description".
+   *       description: Props.string,
+   *
+   *       // A required enum prop named "category".
+   *       category: Props.oneOf(['News','Photos']).isRequired,

+   *       // A prop named "dialog" that requires an instance of Dialog.
+   *       dialog: Props.instanceOf(Dialog).isRequired
+   *     },
+   *     render: function() { ... }

+   * A more formal specification of how these methods are used:
+   *
+   *   type := array|bool|func|object|number|string|oneOf([...])|instanceOf(...)
+   *   decl := ReactPropTypes.{type}(.isRequired)?
+   *
+   * Each and every declaration produces a function with the same signature. This
+   * allows the creation of custom validation functions. For example:
+   *
+   *  var MyLink = React.createClass({
+   *    propTypes: {
+   *      // An optional string or URI prop named "href".
+   *      href: function(props, propName, componentName) {

+   *        if (propValue != null && typeof propValue !== 'string' &&
+   *            !(propValue instanceof URI)) {
