/**
 * @file Ecore.h
 * @brief The file that provides the program utility, main loop and timer
 *        functions.
 *
 * This header provides the Ecore event handling loop.  For more
 * details, see @ref Ecore_Main_Loop_Group.
 *
 * For the main loop to be of any use, you need to be able to add events
 * and event handlers.  Events for file descriptor events are covered in
 * @ref Ecore_FD_Handler_Group.
 *
 * Time functions are covered in @ref Ecore_Time_Group.
 *
 * There is also provision for callbacks for when the loop enters or
 * exits an idle state. See @ref Idle_Group for more information.
 *
 * Functions are also provided for spawning child processes using fork.
 * See @ref Ecore_Exe_Basic_Group and @ref Ecore_Exe_Signal_Group for
 * more details.
