dwm draws a small border around windows to indicate the focus state.

+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

+.SH FILES
+The files containing programs to be started along with dwm are searched for in

+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.
