+/**
+ * [Deprecated] An `ext-libev` based event loop.
+ *
+ * This uses an [unofficial `libev` extension](https://github.com/m4rw3r/php-libev),
+ * that provides an interface to `libev` library.
+ * `libev` itself supports a number of system-specific backends (epoll, kqueue).
+ *
+ * This loop does only work with PHP 5.
+ * An update for PHP 7 is [unlikely](https://github.com/m4rw3r/php-libev/issues/8)
+ * to happen any time soon.
+ *
+ * @see https://github.com/m4rw3r/php-libev
+ * @see https://gist.github.com/1688204
+ * @deprecated 1.2.0, use [`ExtEvLoop`](#extevloop) instead.
