<LI>A call to this routine with <code>close=.true.</code> implies a call
to <code>MPI_Finalize</code>, after which no parallel routine may be called.

<LI>If the user whishes to use multiple communication contexts in the
same program, or to enter and exit multiple times into the parallel
environment, this routine may be called to
selectively close the contexts with <code>close=.false.</code>, while on
the last call it should be called with <code>close=.true.</code> to
shutdown in a clean way the entire parallel environment.
