information about sopc_builder command line

Hi

I use SOPC builder (in GUI mode) to describe my architecture and I would like to know what I could do using the sopc_builder command line in the "Nios II command shell" window.

The help for this command line is given below:

bash-3.1$ sopc_builder -h
Usage: sopc_builder   <system-name>
Run SOPC Builder(tm) for specified system.
   OPTION                    DESCRIPTION
   --generate                Equivalent to pressing 'Generate' button
   --generate=<switches>     Generate with additional command-line switches
   --debug_log=<filename>    Send debugging output to <filename>
   --no_splash               Suppress splash-screen display

                             component class.ptf UI scripts
   --update_classes_and_exit Update ~/.sopc_builder/install.ptf with
                                   component class.ptf file locations and exit

   MODE

   -v, --version            Display version information
   -s                       Silent mode; don't display command-line
   -o                       Display command-line without executing
   -b  Backend mode; run generator directly (no Java)
                            (custom -I<dir> flags accepted in backend mode)

I would like to learn more about the " --script" option. What kind of command can we use in this script file?

I couldn't find any litterature about that.
