# This script does all the magic calls to automake/autoconf and
# friends that are needed to configure a cvs checkout. You need a
# couple of extra development tools to run this script successfully.
#
# If you are compiling from a released tarball you don't need these
# tools and you shouldn't use this script.  Just call ./configure
# directly.
