-Patents.

-The BSD-Compress algorithm used for packet compression is the same as
-that used in the Unix "compress" command. It was apparently covered
-by U.S. patents 4,814,746 (owned by IBM) and 4,558,302 (owned by
-Unisys), and corresponding patents in various other countries (but not
-Australia). Apparently the Unisys patent expired in the US on 20 June
-2003, but the IBM patent is still pending.
-
-If these patents are of concern in your situation, you can build the
-package without including BSD-Compress. To do this, edit
-net/ppp-comp.h to change the definition of DO_BSD_COMPRESS to 0. The
-bsd-comp.c files are then no longer needed, so the references to
-bsd-comp.o may optionally be removed from the Makefiles.
