============
+Changes since 3.07: * Fixed some bugs in my port of `t3d'.
+ * Added `penetrate' and `deluxe' hacks.
+ * When linking against Motif 2.x, also link against XPM.
+ * Added support for using /proc/interrupts for idle
+ detection on Linux. Now xscreensaver shouldn't kick
+ in when the user is active on a non-X virtual console.
+ * Upgraded to autoconf 2.13.
Changes since 3.06: * Configure tweaks (sometimes -lXmu wasn't getting linked
in properly; check for _Xsetlocale in -lXintl.)
* Portability fixes for sonar.c.
