Instead of starting an interactive toplevel-loop, the system will execute the
goal goal. goal is given in normal Prolog syntax, and has to be
quoted if it contains any characters that would normally be interpreted by the
shell. The -e option can be used together with the -b option and is executed
afterwards.
The exit status of the ECLiPSe process reflects success or failure of the
executed Prolog goal (0 for success, 1 for failure).
