.SH DESCRIPTION
This manual page briefly documents the \fBsymphony\fP command.
.PP
\fBsymphony\fP is a generic MILP solver that can be invoked from the command
line (through an interactive shell or in a batch mode), or by linking to the
provided callable library. When no options are given \fBsymphony\fP enters
the interactive shell mode. Otherwise the program enters the batch mode,
for which a summary of options is included below.

.SH OPTIONS
