/* See LICENSE file for copyright and license details.
*
* The dusk 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 dusk 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 workspace. The focus history is remembered through a stack list
* on each workspace. A workspace client area is restricted on a per monitor
* basis.
*
* Keys and workspace rules are organized as arrays and defined in config.h.
*
* To understand everything else, start reading main().
