# Supplement various targets so that we can build ROMIO as well.  Note
# that we only build and install ROMIO if ROMIO was selected in
# configure, but we *always* [try to] clean, distclean, and uninstall
# ROMIO.  This counts for the corner case where a user could do:
#
# ./configure --with-romio
# make all install
# ./configure --without-romio
# make uninstall distclean
#
# If we didn't always traverse into the romio/ directory for uninstall
# and clean, ROMIO will still be left installed, which would not be
# social for us to do.  This scenario doesn't account for all cases
# (mainly because ROMIO still has its own configure script) but it
# does handle the majority of cases.  For example, the following
# scenario won't be handled correctly:
#
# ./configure --with-romio
# make all install
# make distclean
# ./configure --without-romio
# make uninstall
#
# ROMIO will still left installed after this becuase ROMIO's
# ./configure won't have been triggered again, and therefore there
# will be no Makefile (et al.) in the romio/ directory to travese and
# do the uninstall.  
#
# Someday, when ROMIO is fully integrated into LAM, this won't be an
# issue.

# Need to have a separate $(MAKE) invocation for the "all-done" target
# so that make won't perform the "all-done" target before the
# $(romio_all_target).  This is the only way to force/guarantee the
# ordering.

# Be sure to set LAMHOME properly so that hcc/hcp/hf77 use the right

# have a LAM installed, and already have LAMHOME set somewhere else).

# Another bug in ROMIO -- we have to go set the unix permissions on
# directories under $LAMHOME/include to be 755 again.  ROMIO does a
# chmod 644 $LAMHOME/include/* -- ick!  The ROMIO authors have been
# notified of this.  13 June 1999/JMS.

# Automakeizm -- check to see if we already built ROMIO.  "make
# install" implicitly invokes "make all" first (in a roundabout way).
