/**
 * \mainpage Overall design of Tarsnap-GUI
 *
 * \section Objects Main objects
 *
 * - Frontend: \ref MainWindow or \ref SetupWizard
 * - Backend: \ref TaskManager
 * - Overall owner: \ref AppGui or \ref AppCmdline
 *
 * \section signals Signals between frontend and backend
 *
 * The connections between the frontend and backend are defined in
 * src/app-gui.cpp.  Naming conventions:
 * - Following the convention of the Qt objects, signals should be
 *   in the past tense, while slots should be present tense.  For
 *   example, a typical "query chain" might be:
 *       <table><tr>
 *       <td>FRONTEND</td><td>SIGNAL</td><td>\ref tarsnapVersionRequested</td>
 *       </tr><tr>
 *       <td>BACKEND</td><td>SLOT</td><td>\ref tarsnapVersionFind</td>
 *       </tr><tr>
 *       <td>BACKEND</td><td>SIGNAL</td><td>\ref tarsnapVersionFound</td>
 *       </tr><tr>
 *       <td>FRONTEND</td><td>SLOT</td><td>\ref tarsnapVersionResponse</td>
 *       </tr></table>
 *   If at all possible, keep the same prefix for all four items;
 *   this will make grepping much easier.
