so on.  The patch should be reworked and properly tested.

 dwm \- dynamic window manager
 .SH SYNOPSIS
 .B dwm
 .RB [ \-v ]
 .SH DESCRIPTION
-dwm is a dynamic window manager for X. It manages windows in tiling and
-floating modes. Either mode can be applied dynamically, optimizing the
+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 area. The master
-area contains the window which currently needs most attention, whereas the
-stacking area contains all other windows. In floating mode windows can be
-resized and moved freely. Dialog windows are always managed floating,
-regardless of the mode selected.
+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. Each window can be tagged with one or multiple
 tags. Selecting certain tags displays all windows with these tags.
 .P
-dwm contains a small status bar which displays all available tags, the mode,
-the title of the focused window, and the text read from standard input. 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 clients are indicated with an empty square in
-the top left corner.
+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.

 .SH CUSTOMIZATION
 dwm is customized by creating a custom config.h and (re)compiling the source
 code. This keeps it fast, secure and simple.
-.SH CAVEATS
-The status bar may display
-.BR "broken pipe"
-when dwm has been started by
-.BR xdm (1),
-because it closes standard output before executing dwm.
 .SH SEE ALSO

+.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.

- * See LICENSE file for 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.
- *
- * 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().
