+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 xsetroot -name "`date` `uptime | sed 's/.*,//'`"
+ do
+ sleep 1
+ done &
+ exec dwm
+
+
+Configuration
+-------------
+The configuration of dwm is done by creating a custom config.h
+and (re)compiling the source code.

+.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 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 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
+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.
+.P
+On start, dwm can start additional programs that may be specified in two special
+shell scripts (see the FILES section below), autostart_blocking.sh and
+autostart.sh. The former is executed first and dwm will wait for its
+termination before starting. The latter is executed in the background before
+dwm enters its handler loop.
+.P
+Either of these files may be omitted.
+.SH OPTIONS
+.TP
+.B \-v
+prints version information to stderr, then exits.

+.TP
+.B Mod1\-[1..n]
+View all windows with nth tag.
+.TP
+.B Mod1\-0
+View all windows with any tag.
+.TP
+.B Mod1\-Control\-[1..n]

+.TP
+.B Mod1\-Shift\-q
+Quit dwm.
+.SS Mouse commands
+.TP
+.B Mod1\-Button1
+Move focused window while dragging. Tiled windows will be toggled to the floating state.
+.TP
+.B Mod1\-Button2
+Toggles focused window between floating and tiled state.
+.TP
+.B Mod1\-Button3
+Resize focused window while dragging. Tiled windows will be toggled to the floating state.
+.SH FILES
+The files containing programs to be started along with dwm are searched for in
+the following directories:
+.IP "1. $XDG_DATA_HOME/dwm"
+.IP "2. $HOME/.local/share/dwm"
+.IP "3. $HOME/.dwm"
+.P
+The first existing directory is scanned for any of the autostart files below.
+.TP 15
+autostart.sh
+This file is started as a shell background process before dwm enters its handler
+loop.
+.TP 15
+autostart_blocking.sh
+This file is started before any autostart.sh; dwm waits for its termination.
+.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),
+.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.

+slstatus - suckless status
+==========================
+slstatus is a small tool for providing system status information to other
+programs over the EWMH property of the root window (used by dwm(1)) or
+standard input/output. It is designed to be as efficient as possible by
+only issuing the minimum of system calls required.
+
+
+Features
+--------
+- Battery percentage/state/time left
+- Cat (read file)
+- CPU usage
+- CPU frequency
+- Custom shell commands
+- Date and time
+- Disk status (free storage, percentage, total storage and used storage)
+- Available entropy
+- Username/GID/UID
+- Hostname
+- IP address (IPv4 and IPv6)
+- Kernel version
+- Keyboard indicators
+- Keymap
+- Load average
+- Network speeds (RX and TX)
+- Number of files in a directory (hint: Maildir)
+- Memory status (free memory, percentage, total memory and used memory)
+- Swap status (free swap, percentage, total swap and used swap)
+- Temperature
+- Uptime
+- Volume percentage
+- WiFi signal percentage and ESSID
+
+
+Requirements
+------------
+Currently slstatus works on FreeBSD, Linux and OpenBSD.
+In order to build slstatus you need the Xlib header files.
+
+- For volume percentage on Linux the kernel module `snd-mixer-oss` must be
+ loaded.
+- For volume percentage on FreeBSD, `sndio` must be installed.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (slstatus is installed into the
+/usr/local namespace by default).
+
+Afterwards enter the following command to build and install slstatus (if
+necessary as root):
+
+ make clean install
+
+
+Running slstatus
+----------------
+See the man page for details.
+
+
+Configuration
+-------------
+slstatus can be customized by creating a custom config.h and (re)compiling the
+source code. This keeps it fast, secure and simple.

+.Sh SYNOPSIS
+.Nm
+.Op Fl s
+.Op Fl 1
+.Sh DESCRIPTION
+.Nm
+is a small tool for providing system status information to other programs
+over the EWMH
+.Em WM_NAME
+property of the root window (used by
+.Xr dwm 1 ) or standard input/output. It is designed to be as efficient as possible by
+only issuing the minimum of system calls required.
+.P
+By default,
+.Nm
+outputs to WM_NAME.
+.Sh OPTIONS
+.Bl -tag -width Ds
+.It Fl v
+Print version information to stderr, then exit.
+.It Fl s
+Write to stdout instead of WM_NAME.
+.It Fl 1
+Write once to stdout and quit.
+.El
+.Sh CUSTOMIZATION
+.Nm
+can be customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.Sh SIGNALS
+.Nm
+responds to the following signals:
+.Pp
+.Bl -tag -width TERM -compact
+.It USR1
+Triggers an instant redraw.
+.El
+.Sh AUTHORS
+See the LICENSE file for the authors.
