++.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.

+ .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_CONFIG_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.
