You must comply with the GNU General Public License version 2 in all respects for all of the code used other than the "OpenSSL" code. If you modify this file, you may extend this exception to your version of the file, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version of this file. \endcode Also note shipping OpenSSL might cause \l{Import and Export Restrictions} to apply. */ /*! \module QtNetwork \title Qt Network C++ Classes \ingroup modules \qtcmakepackage Network \qtvariable network \brief Provides classes to make network programming easier and portable.
