+dwm - dynamic window manager
+============================
+dwm is an extremely fast, small, and dynamic window manager for X.
+
+
+Requirements
+------------
+In order to build dwm you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (dwm is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install dwm (if
+necessary as root):
+
+    make clean install
+
+
+Running dwm
+-----------
+Add the following line to your .xinitrc to start dwm using startx:
+
+    exec dwm
+
+In order to connect dwm to a specific display, make sure that
+the DISPLAY environment variable is set correctly, e.g.:
+
+    DISPLAY=foo.bar:1 exec dwm
+
+(This will start dwm on display :1 of the host foo.bar.)
+
+In order to display status info in the bar, you can do something
+like this in your .xinitrc:
+
+    while true
+    do
+        echo `date` `uptime | sed 's/.*,//'`
+        sleep 1
+    done | dwm
+
+
+Configuration
+-------------
+The configuration of dwm is done by creating a custom config.h
+and (re)compiling the source code.

+.TH DWM 1 dwm-VERSION
+.SH NAME
+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
+versatile layouts. Either layout can be applied dynamically, optimizing the
+environment for the application in use and the task performed.
+.P
+In tiling layout windows are managed in a master and stacking area. The master
+area contains the windows which currently need most attention, whereas the
+stacking area contains all other windows. In versatile layout windows can be
+resized and moved freely. Dialog windows are always managed versatile,
+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 layout,
+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 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 OPTIONS
+.TP
+.B \-v
+prints version information to standard output, then exits.
+.SH USAGE
+.SS Status bar
+.TP
+.B Standard input
+is read and displayed in the status text area.
+.TP
+.B Button1
+click on a tag label to display all windows with that tag, click on the layout
+label toggles between tiling and versatile layout.
+.TP
+.B Button3
+click on a tag label adds/removes all windows with that tag to/from the view.
+.TP
+.B Button4
+click on the layout label increases the number of windows in the master area (tiling layout only).
+.TP
+.B Button5
+click on the layout label decreases the number of windows in the master area (tiling layout only).
+.TP
+.B Mod1-Button1
+click on a tag label applies that tag to the focused window.
+.TP
+.B Mod1-Button3
+click on a tag label adds/removes that tag to/from the focused window.
+.SS Keyboard commands
+.TP
+.B Mod1-Shift-Return
+Start
+.BR xterm (1).
+.TP
+.B Mod1-Tab
+Focus next window.
+.TP
+.B Mod1-Shift-Tab
+Focus previous window.
+.TP
+.B Mod1-Return
+Zooms/cycles current window to/from master area (tiling layout), toggles maximization of current window (versatile layout).
+.TP
+.B Mod1-g
+Grow master area (tiling layout only).
+.TP
+.B Mod1-s
+Shrink master area (tiling layout only).
+.TP
+.B Mod1-i
+Increase the number of windows in the master area (tiling layout only).
+.TP
+.B Mod1-d
+Decrease the number of windows in the master area (tiling layout only).
+.TP
+.B Mod1-Shift-[1..n]
+Apply
+.RB nth
+tag to current window.
+.TP
+.B Mod1-Shift-0
+Apply all tags to current window.
+.TP
+.B Mod1-Control-Shift-[1..n]
+Add/remove
+.B nth
+tag to/from current window.
+.TP
+.B Mod1-Shift-c
+Close focused window.
+.TP
+.B Mod1-space
+Toggle between tiling and versatile layout (affects all windows).
+.TP
+.B Mod1-Shift-space
+Toggle focused window between versatile and non-versatile state (tiling layout only).
+.TP
+.B Mod1-[1..n]
+View all windows with
+.BR nth
+tag.
+.TP
+.B Mod1-0
+View all windows with any tag.
+.TP
+.B Mod1-Control-[1..n]
+Add/remove all windows with
+.BR nth
+tag to/from the view.
+.TP
+.B Mod1-Shift-q
+Quit dwm.
+.SS Mouse commands
+.TP
+.B Mod1-Button1
+Move current window while dragging (versatile layout only).
+.TP
+.B Mod1-Button2
+Zooms/cycles current window to/from master area (tiling layout), toggles maximization of current window (versatile layout).
+.TP
+.B Mod1-Button3
+Resize current window while dragging (versatile layout only).
+.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 SEE ALSO
+.BR dmenu (1)
+.SH BUGS
+The status bar may display
+.BR "EOF"
+when dwm has been started by an X session manager like
+.BR xdm (1),
+because those close standard output before executing dwm.
+.P
+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. As a workaround
+you can use JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or you
+can set the following environment variable (to use the older Motif
+backend instead):
+.BR AWT_TOOLKIT=MToolkit .

+ *
+ * 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 layout is
+ * represented by the lt pointer.
+ *
+ * To understand everything else, start reading main.c:main().
