# This script does all the magic calls to automake/autoconf and friends
# that are needed to configure a Subversion checkout.  As described in
# the file HACKING you need a couple of extra 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.
