+ * 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 mode is
+ * represented by the arrange() function pointer, which wether points to
+ * dofloat() or dotile(). 
+ *
+ * To understand everything else, start reading main.c:main().

-			<h3>dynamic window manager</h3>
-		</center>
-		<h3>Description</h3>
-		<p>
-		dwm is a dynamic window manager for X11.
-		</p>
-		<h4>Background</h4>
-		<p>
-		As founder and main developer of wmii I came to the conclusion that
-		wmii is too clunky for my needs. I don't need so many funky features
-		and all this hype about remote control through a 9P service, I only
-		want to manage my windows in a simple, but dynamic way. wmii never got
-		finished because I listened to users, who proposed arbitrary ideas I
-		considered useful. This resulted in an extreme <a
-		href="http://www.jwz.org/doc/cadt.html">CADT</a> development model,
-		which was a mistake. Thus the philosophy of dwm is simply <i>to fit my
-		needs</i> (maybe yours as well). That's it.
-		</p>
-		<h4>Differences to ion, larswm, and wmii</h4>
-		<p>
-		In contrast to ion, larswm, and wmii, dwm is much smaller, faster and simpler.
-		</p>
-		<ul>
-			<li>
-			dwm has no Lua integration, no 9P support, no editable
-			tagbars, no shell-based configuration, no remote control, and comes
-			without any additional tools like printing the selection or warping
-			the mouse.
-			</li>
-			<li>
-			dwm is only a single binary, it's source code is intended to never
-			exceed 2000 SLOC.
-			</li>
-			<li>
-			dwm is based on tagging and dynamic window management (however
-			simpler than ion, wmii or larswm). It manages windows in
-			tiling and floating modes. Either mode can be applied dynamically,
-			depending on the application in use and the task performed.
-			</li>
-			<li>
-			dwm doesn't distinguishes between layers, there is no floating or
-			tiled layer. Wether the clients of currently selected tag are in
-			tiled mode or not, you can re-arrange all clients on the fly.
-			Popup- and fixed-size windows are treated floating, however. 
-			</li>
-			<li>
-			dwm is customized through editing its source code, that makes it
-			extremely fast and secure - it does not process any input data
-			which hasn't been known at compile time, except window title names
-			and status text read from standard input. You don't have to learn
-			Lua/sh/ruby or some weird configuration file format (like X
-			resource files), beside C to customize it for your needs,
-			you <b>only</b> have to learn C (at least editing header files).
-			</li>
-			<li>
-			Because dwm is customized through editing its source code, it's
-			pointless to make binary packages of it. This keeps its userbase
-			small and elitist. No novices asking stupid questions.
-			</li>
-			<li>
-			dwm uses 1-pixel borders to provide the maximum of screen real
-			estate to clients. Small titlebars are only drawn in front of
-			unfocused clients.
-			</li>
-			<li>
-			dwm reads from standard input to print arbitrary status text (like
-			the date, load, battery charge). That's much simpler than
-			larsremote, wmiir and what not...
-			</li>
-			<li>
-			It can be downloaded and distributed under the conditions
-			of the <a href="http://10kloc.org/cgi-bin/hgwebdir.cgi/dwm?f=f10eb1139362;file=LICENSE;style=raw">MIT/X Consortium license</a>.
-			</li>
-			<li>
-			Optionally you can install <b>dmenu</b> to extend dwm with a wmii-alike menu.
