+/**
+ * A Mustache Template loader for inline templates.
+ *
+ * With the InlineLoader, templates can be defined at the end of any PHP source
+ * file:
+ *
+ *     $loader  = new Mustache_Loader_InlineLoader(__FILE__, __COMPILER_HALT_OFFSET__);
+ *     $hello   = $loader->load('hello');
+ *     $goodbye = $loader->load('goodbye');
+ *
+ *     __halt_compiler();
+ *
+ *     @@ hello
+ *     Hello, {{ planet }}!
+ *
+ *     @@ goodbye
+ *     Goodbye, cruel {{ planet }}
+ *
+ * Templates are deliniated by lines containing only `@@ name`.
+ *
+ * The InlineLoader is well-suited to micro-frameworks such as Silex:
+ *
+ *     $app->register(new MustacheServiceProvider, array(
+ *         'mustache.loader' => new Mustache_Loader_InlineLoader(__FILE__, __COMPILER_HALT_OFFSET__)
+ *     ));
+ *
+ *     $app->get('/{name}', function ($name) use ($app) {
+ *         return $app['mustache']->render('hello', compact('name'));
+ *     })
+ *     ->value('name', 'world');
+ *
+ *     // ...
+ *
+ *     __halt_compiler();
+ *
+ *     @@ hello
+ *     Hello, {{ name }}!
