# This script builds the files necessary to configure this package for
# development.  Once you run this script, you will need GNU make,
# autoconf, and automake to build the software.  You must run "make
# dist" if you the wish to create a source tree that can be built
# without these tools.
#
# You should generally only need to run this script if you just
# checked sfs out of a CVS repository, or else somehow badly mangled
# the Makefile.
