+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

-shell scripts (see the FILES section below), autostart_blocking.sh and

-The files containing programs to be started along with dwm are searched for in

 .SH CUSTOMIZATION
 dwm is customized by creating a custom config.h and (re)compiling the source
 code. This keeps it fast, secure and simple.
