work with plain Makefiles under an automake'ed directory tree

[Steven Woody]

hi,


in my automake-managed directory tree, there are some external sources
which came with plain Makefiles.  i want to ask you folks, when i type
in a 'make' or 'make clean' at the top directory, how can i let the
automake dive into those external source directories and run 'make '
and 'make clean' for them?
