 afkcron
 =======
-afkcron reads a configuration which specifies programs to launch after n seconds of afk time. 
-Once the user is afk for those seconds, it then starts the program. 
+afkcron simply reports the idle time of the X11 server to a shell script.
+
+Originally, it was reading config files and also handling the return of the
+user by decreasing priority of launched processes or killing them etc.
+
+Now I considered it's best for it to be rather stupid and delegate this 
+to a shell script for example. 
+
