+/**
+ * @defgroup PJ_SOCK Socket Abstraction
+ * @ingroup PJ_IO
+ * @{
+ *
+ * The PJLIB socket abstraction layer is a thin and very portable abstraction
+ * for socket API. It provides API similar to BSD socket API. The abstraction
+ * is needed because BSD socket API is not always available on all platforms,
+ * therefore it wouldn't be possible to create a trully portable network
+ * programs unless we provide such abstraction.
+ *
+ * Applications can use this API directly in their application, just
+ * as they would when using traditional BSD socket API, provided they
+ * call #pj_init() first.
+ *
+ * \section pj_sock_examples_sec Examples
+ *
+ * For some examples on how to use the socket API, please see:
+ *
+ * - \ref page_pjlib_sock_test
+ * - \ref page_pjlib_select_test
+ * - \ref page_pjlib_sock_perf_test
