+.SH MAME
+coreupdownd - Dynamically enable and disable CPU' to only use one during low CPU usage
+.SH SYNPOSIS
+coreupdownd
+.SH DESCRIPTION
+The
+.B coreupdownd
+daemon dynamically turns all CPU cores, except except
+the main one, on and off depending on CPU usage.
+.PP
+The daemon periodically determines what the CPU usage
+would be if only the main CPU core was enable. If it
+would be saturated, the other cores are enabled, otherwise
+the they are disabled.
+.PP
+This is designed as a workaround for virtual machines
+that have input performance issues (keyboard input lag
+and keys getting stuck) when more than one CPU core is
+online.
