This is the OMPI contrib system. It is (far) less functional and
flexible than the OMPI MCA framework/component system.
Each contrib package must have either both a configure.params and a
configure.m4 file, or it must have an autogen.subdirs file.
If it has (configure.params, configure.m4), configure.params can be
just like any MCA component's: specify a list of files to create
during AC_OUTPUT. The configure.m4 file will be slurped up into the
main configure script, just like other MCA components. Note that
there is currently no "no configure" option for contrib packages --
you *must* have a configure.m4 (even if all it does it call $1).
Feel free to fix this situation if you want -- see:
https://svn.open-mpi.org/trac/ompi/ticket/1162
:-)
If it has an autogen.subdirs file, then it needs to be a subdirectory
that is autogen-able (see the vt project for an example).
