+dwm - dynamic window manager
+----------------------------
+dwm is an extremely fast, small, and dynamic X11 window manager.
+
+
+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/.*://; s/,//g'`
+ sleep 1
+ done | dwm
+
+
+Configuration
+-------------
+The configuration of dwm is done by creating a custom config.h
+and (re)compiling the source code.

+.TH DMENU 1 d-0.0
+.SH NAME
+dmenu \- dynamic menu
+.SH SYNOPSIS
+.B dmenu
+.RB [ \-v ]
+.RB [ \-t
+.IR title ]
+.SH DESCRIPTION
+.SS Overview
+.B dmenu
+is a generic, highly customizable, and efficient menu for the X Window System,
+originally designed for
+.BR dwm (1).
+It supports arbitrary, user defined menu contents.
+.SS Options
+.TP
+.B \-v
+prints version information to stdout, then exits.
+.TP
+.BI \-t " title"
+displays
+.I title
+above the menu.
+.SS Usage
+.B dmenu
+reads a list of newline-separated items from stdin and creates a menu.
+When the user selects an item or enters any text and presses Enter, his choice
+is printed to stdout and
+.B dmenu
+terminates.
+.SS Keyboard Control
+.B dmenu
+is completely controlled by the keyboard. The following keys are recognized:
+.TP 2
+Any printable character
+appends the character to the text in the input field. This works as a filter:
+only items containing this text will be displayed.
+.TP 2
+Left/Right (Control-p/Control-n)
+select the previous/next item.
+.TP 2
+Tab (Control-i)
+copy the selected item to the input field.
+.TP 2
+Enter (Control-j)
+confirm selection and quit (print the selected item to stdout).
+.TP 2
+Shift-Enter (Shift-Control-j)
+confirm selection and quit (print the text in the input field to stdout).
+.TP 2
+Escape (Control-[)
+quit without selecting an item.
+.TP 2
+Backspace (Control-h)
+remove enough characters from the input field to change its filtering effect.
+.TP 2
+Control-u
+remove all characters from the input field.
+.SS Exit codes
+.B dmenu
+returns
+.B 0
+if Enter is pressed on termination,
+.B 1
+if Escape is pressed.
+.SH SEE ALSO
+.BR dwm (1)
