Finished adding and pruning all the the Options.

Cleaned up a bunch of man syntax, so it should be 'more' readable (making the
assumption that man source is ever readable :p).

I am moving on to the "description" and "see also" sections next.

This commit was SVN r9077.

.SH QUICK SUMMARY
If you are simply looking for how to run an MPI application, you
probably want to use the following command line:
.sp
.RS
shell$ mpirun -np 4 my_mpi_application
.RE
.PP
This will run 4 copies of
.I my_mpi_application
in your current run-time environment (if running under a supported
resource manager, Open MPI's
.I orterun
will usually automatically use the corresponding resource manager
process starter, as opposed to, for example,
.I rsh
or
.IR ssh ),
\fBshell$\fP mpirun -np 4 my_mpi_application
This will run 4 copies of \fImy_mpi_application\fR in your current run-time
environment (if running under a supported resource manager, Open MPI's
\fIorterun\fR will usually automatically use the corresponding resource manager
process starter, as opposed to, for example, \fIrsh\fR or \fIssh\fR ),
scheduling (by default) in a round-robin fashion by CPU slot. See the
rest of this page for more details.

.\" Options Section
.\" **************************
.SH OPTIONS
There are two forms of the
.IR mpirun
command -- one for programs (i.e., SPMD-style applications), and one
for application schemas (see appschema(5)). Both forms of
.IR mpirun
use the following options by default:
.I \-nger
.IR \-w .
These may each be overriden by their counterpart options, described
below.
.PP
Additionally,
.
.I mpirun
will send the name of the directory where it was invoked on the local
node to each of the remote nodes, and attempt to change to that
directory. See the "Current Working Directory" section, below.
