# This script does a 'make installworld' using the *new* versions of all
# commands to do the work. This is important when a major incompatible
# change is made, a change such that the old-binaries won't work when
# running on the new-kernel. This script was written for the change to
# 64-bit time_t on FreeBSD/Sparc64, but it is not specific to that.
#
# IMPORTANT: This script does require that you ARE RUNNING ON the
# new kernel that matches the 'world' that you want to install.
