 .SH NAME
 dwm \- dynamic window manager
 .SH SYNOPSIS
 .B dwm
 .RB [ \-v ]
 .SH DESCRIPTION
-.B dwm
-is a dynamic window manager for X11. It manages windows in tiling and floating
-modes. Either mode can be applied dynamically, depending on the application in
-use and the task performed.
+dwm is a dynamic window manager for X. It manages windows in tiled, monocle
+and floating layouts. Either layout can be applied dynamically, optimising the
+environment for the application in use and the task performed.
 .P
-In tiling mode windows are managed in a master and stacking column. The master
-column contains the window which needs most attention at a time, whereas the
-stacking column contains all other windows in a stack.  Dialog windows are
-managed floating, however. In floating mode windows can be resized and moved
-freely.
+In tiled layouts windows are managed in a master and stacking area. The master
+area on the left contains one window by default, and the stacking area on the
+right contains all other windows. The number of master area windows can be
+adjusted from zero to an arbitrary number. In monocle layout all windows are
+maximised to the screen size. In floating layout windows can be resized and
+moved freely. Dialog windows are always managed floating, regardless of the
+layout applied.
 .P
-Windows are grouped by tags. All windows with a specific tag can be viewed at a
-time. But each window may contain more than one tag, which makes it visible in
-several views.
+Windows are grouped by tags. Each window can be tagged with one or multiple
+tags. Selecting certain tags displays all windows with these tags.
 .P
-.B dwm
-consists of a small status bar which reads the text displayed from standard
-input, if written. It draws 1-pixel borders around windows to indicate the
-focus state. Unfocused windows contain a small bar in front of the window
-displaying the tags and the window title.
+Each screen contains a small status bar which displays all available tags, the
+layout, the title of the focused window, and the text read from the root window
+name property, if the screen is focused. A floating window is indicated with an
+empty square and a maximised floating window is indicated with a filled square
+before the windows title.  The selected tags are indicated with a different
+color. The tags of the focused window are indicated with a filled square in the
+top left corner.  The tags which are applied to one or more windows are
+indicated with an empty square in the top left corner.
+.P
+dwm draws a small border around windows to indicate the focus state.

 .SH CUSTOMIZATION
-.B dwm
-is customized through editing its source code.  This keeps it fast, secure and
-simple. The source code contains the
-.I CUSTOMIZE
-keyword to highlight relevant portions for customization.
+dwm is customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.SH SEE ALSO
+.BR dmenu (1),
+.BR st (1)
+.SH ISSUES
+Java applications which use the XToolkit/XAWT backend may draw grey windows
+only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
+JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
+are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
+environment variable
+.BR AWT_TOOLKIT=MToolkit
+(to use the older Motif backend instead) or running
+.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
+or
+.B wmname LG3D
+(to pretend that a non-reparenting window manager is running that the
+XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
+.BR _JAVA_AWT_WM_NONREPARENTING=1 .
+.SH BUGS
+Send all bug reports with a patch to hackers@suckless.org.

-		</center>
-		<h3>Description</h3>
-		<p>
-		dwm is a dynamic window manager for X11.
-		</p>
-		<h4>Philosophy</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 menu, 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 don'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.
-			</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>.

-		<h3>Development</h3>
-		<p>
-		dwm is actively developed in parallel to wmii. You can <a href="http://10kloc.org/cgi-bin/hgwebdir.cgi/dwm">browse</a> its source code repository or get a copy using <a href="http://www.selenic.com/mercurial/">Mercurial</a> with following command:
