+Subject: [PATCH] This Patch replaces the default quit behavior with an dmenu
+ prompt. Possible selections are (Quit DWM?) "yes", "no" and "restart". The
+ additional confirmation can save your work from accidentally hitting the quit
+ key by requiring two additional keystrokes (y/yes and RET). Additionally it
+ allows for restarting / reloading dwm without ending the xsession and closing
+ all open x windows. To abort press ESC or n/no and RET.
