 OTHER SOFTWARE CREDITS

+----------------------
 We originally included a modified implementation of some of the Sparker
 (serial sparse BLAS)  material; this has been completely rewritten, way
 beyond the intention(s) and responsibilities of the original developers.

 SERIAL
-
+------
 Configuring with --enable-serial will provide a fake MPI stub library
 that enables running in pure serial mode; no MPI installation is needed
 in this case (but note that the fake MPI stubs are only guaranteed to
 cover what we use internally, it's not a complete replacement). 
 
 LONG INTEGERS
-
+-------------
 We have an experimental flag --enable-long-integers that will enable 
 having 8-byte integer data, allowing an index space larger than 2G; some
 small cases have been tested but we do not offer full guarantee (yet).
