# Each rule that does this needs to have dependencies on any
# other COMPONENTs that have to be processed first.  See
# The install-tools target here for an example.
#
# dist* targets are special: these do not occur in lower-level
# Makefiles.  Instead, these are all implemented only here.
# They run the appropriate install targets with DESTDIR set.
#
# Also, we have a number of targets COMPONENT which run
# dist-COMPONENT, for convenience.
#
# The Makefiles invoked with -C from the toplevel should
# generally have the following targets:
#       all  build  install  clean  distclean
