* This module is intended to encapsulate ncurses's interface to pointing
* devices.
*
- * The first method used is xterm's internal mouse-tracking facility.
- * The second is Alessandro Rubini's GPM server.
+ * The primary method used is xterm's internal mouse-tracking facility.
+ * Additional methods depend on the platform:
+ * Alessandro Rubini's GPM server (Linux)
+ * sysmouse (FreeBSD)
+ * special-purpose mouse interface for OS/2 EMX.

* Notes for implementors of new mouse-interface methods:
