-Subject: [PATCH] Add support for managing external status bars
-
-This patch allows dwm to manage other status bars such as
-polybar/lemonbar without them needing to set override-redirect. For
-all intents and purposes, DWM treats this bar as if it were its own
-and as a result helps the status bar and DWM live in harmony.
-
-This has a few advantages
-* The bar does not block fullscreen windows
-* DWM makes room for the status bar, so windows do not overlap the bar
-* The bar can be hidden/killed and DWM will not keep an unsightly gap
-  where the bar was
-* DWM receives EnterNotify events when your cursor enters the bar
-
-To use another status bar, set usealtbar to 1 in your config.h and set
-altbarclass to the class name (can be found using xprop) to the class
-name of your status bar. Also make sure that if your status bar will
-be displayed on top, topbar is set to 1 in your config, and if it will
-be displayed on bottom, topbar is set to 0. This patch does not
-support bars that are not docked at the top or at the bottom of your
-monitor.
-
-This verison of the patch fixes handling of polybar's tray.
-
-The patch is developed at https://github.com/mihirlad55/dwm-anybar
