 *
 * 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 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 fetch an X event from the event queue are blocking.  Due reading
 * 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. The event handlers of dwm are organized in an
 * array which is accessed whenever a new event has been fetched. This allows
 * event dispatching in O(1) time.
 *
 * Each child of the root window is called a client, 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.  For each client dwm
 * creates a small title window, which is resized whenever the (_NET_)WM_NAME
 * properties are updated or the client is moved/resized.
 *
 * Keys and tagging rules are organized as arrays and defined in the config.h
 * file. These arrays are kept static in event.o and tag.o respectively,
 * because no other part of dwm needs access to them.  The current layout is
 * represented by the lt pointer.
 *
 * To understand everything else, start reading main.c:main().
