* 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 window appearance and disappearance. Only one X
* connection at a time is allowed to select for this event mask.

* Calls to fetch an X event from the X event queue connection 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 and without busy-loop quirks. 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

* 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 WM_NAME or
* _NET_WM_NAME properties are updated or the client is resized.

* Keys and tagging rules are organized as arrays and defined in the config.h

* because no other part of dwm needs access to them. The current mode is
