We are working on a prototype system for automatically producing a report describing MPI on the system you are using. This is done by going to the top-level directory and doing
doc/port
Warning: this rebuilds the system, since one of the things the report will
contain is the set of machine-specific parameters used and the total time it
take to build it. If the system that you are running on contains all the
necessary components for producing the report, it will appear in the file
doc/doc1.tex.
