# -*- make -*-

# This make fragment is included by the toplevel make to handle configure
# and setup. It defines a target called startup that when run will init
# the build directory, generate configure from configure.in, create aclocal
# and has rules to run config.status should one of the .in files change.

# Input
#  BUILD - The build director
#  CONVERTED - List of files output by configure $(BUILD) is prepended
#              The caller must provide depends for these files
# It would be a fairly good idea to run this after a cvs checkout.
