/* See LICENSE file for copyright and license details.
*
* 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.
*
* 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 linked client
* list on each monitor, the focus history is remembered through a stack list
* on each monitor. Each client contains a bit array to indicate the tags of a
* client.
*
* Keys and tagging rules are organized as arrays and defined in config.h.
*
* To understand everything else, start reading main().
