+Cody made `main()` have two args, not one, as some versions of clang have a
+defect with the number of args to `main()` though when it comes to 1 arg it is
+only in an error message if say 4 args are used. This is out of an abundance of
+caution as it's quite possible that clang or the ANSI C committee end up further
+changing this.

 Yusuke also noted that there is a bug in the program where right after starting
 it moves towards the right but if you click the mouse it goes back.
