* dynamic window manager is designed like any other X client as well. It is
* driven through handling X events. In contrast to other X clients, a window
- * manager like dwm selects for SubstructureRedirectMask on the root window, to
- * receive events about child window appearance and disappearance. Only one X
- * connection at a time is allowed to select for this event mask by any X
- * server, thus only one window manager instance can be executed at a time.
- * Any attempt to select for SubstructureRedirectMask by any connection after
- * another connection already selected for those events, will result in an
- * error generated by the server. Such errors are reported through calling the
- * current X error handler.
+ * manager selects for SubstructureRedirectMask on the root window, to receive
+ * events about window (dis-)appearance. Only one X connection at a time is
+ * allowed to select for this event mask.
*
- * Calls to pop an X event from the event queue of the X connection are
- * blocking. Due the fact, that dwm reads status text from standard input, a
- * select-driven main loop has been implemented which selects for reads on the
- * X connection and STDIN_FILENO to handle all data smoothly and without
- * busy-loop quirks.. The event handlers of dwm are organized in an array
- * which is accessed whenever a new event has been popped. This allows event
- * dispatching in O(1) time.

- * Each child window of the root window is called a client in window manager
- * terminology, except windows which have set the override_redirect flag.
- * Clients are organized in a global doubly-linked client list, the focus
- * history is remembered through a global stack list. Each client contains an
- * array of Bools of the same size as the global tags array to indicate the
- * tags of a client. There are no other data structures to organize the clients
- * in tag lists, because a single global list is most simple. All clients which
- * have at least one tag enabled of the current tags viewed, will be visible on
- * the screen, all other clients are banned to the x-location 2 * screen width.
- * This avoids having additional layers of workspace handling.
