# Datadraw uses itself to produce one of its files.
# if we have a datadraw installed go ahead and enable
# some extra rules.  FIXME -- do we ultimately need a 2
# stage build like what gcc does?  Build datadraw then
# rebuild again??
#
# If we are cross compiling then we need to search for a 
# datadraw binary to use for the build of dataview.  This can
# either be an installed datadraw in our search path or 
# it can be specified like:
#
# env DATADRAW=/opt/ddr/bin/datadraw ./configure \
#    --host=alpha--netbsd --build=i686--linux
