-# kinstall.sh -- install updated kernel PPP driver in Linux kernel source
-# Michael Callahan callahan@maths.ox.ac.uk 17 May 1995
-#
-# This script is complicated because we want to avoid installing a driver
-# in a kernel if it won't work in that kernel. This means two things:
-# 1) we check the version of the kernel and refuse to install if the
-# kernel is too old;
-# 2) we check that the files already in the kernel aren't more recent
-# than the one we're about to install.
-# If either 1) or 2) occurs then we exit with an error message and don't
-# touch anything.
-#
-# In addition, we have to edit the Makefile in the drivers/net
-# directory to add support for the ppp-comp compression option.
