+ * Usage:
+ * 1. foreign-toplevel
+ * 	  Prints a list of opened toplevels
+ * 2. foreign-toplevel -f <id>
+ *    Focus the toplevel with the given id
+ * 3. foreign-toplevel -a <id>
+ *    Maximize the toplevel with the given id
+ * 4. foreign-toplevel -u <id>
+ *    Unmaximize the toplevel with the given id
+ * 5. foreign-toplevel -i <id>
+ *    Minimize the toplevel with the given id
+ * 6. foreign-toplevel -r <id>
+ * 	  Restore(unminimize) the toplevel with the given id
+ * 7. foreign-toplevel -c <id>
+ *    Close the toplevel with the given id
+ * 8. foreign-toplevel -m
+ *    Continuously print changes to the list of opened toplevels.
+ *    Can be used together with some of the previous options.
