+ * one specific example of useful hooking.
+ *
+ * Note that both the `matcher` and `transformer` must execute synchronously.
+ *
+ * @module Exports
+ * @example
+ * var hook = require('istanbul-lib-hook'),
+ *     myMatcher = function (file) { return file.match(/foo/); },
+ *     myTransformer = function (code, file) {
+ *         return 'console.log("' + file + '");' + code;
