/**

 * @author Vincent Torri
 * @date 2008
 *
 * @section intro_sec Introduction
 *
 * The Evil library is an evil library that ports some evil Unix
 * functions to the Windows (XP or Mobile) platform. The evilness is
 * so huge that the most of the functions are not POSIX or BSD
 * compliant.
 *
 * These functions are intended to be used in the Enlightenment
 * Fundations Libraries only and can be compiled only on Windows.
 *
 * @section evil_sec Evil API Documentation
 *
 * Take a look at the evil documentation of the @ref Dlfcn.
 *
 * Take a look at the demoniac documentation of the @ref Mman.
 *
 * Take a look at the satanic documentation of the @ref Evil.

 * @defgroup Evil Miscellaneous functions ported from Unix.
 *
 * This header provides miscallenaous functions that exist on Unix
 * but not on Windows platform. They try to follow the conformance of
 * the Unix versions.
