Slic3r $Slic3r::VERSION is a STL-to-GCODE translator for RepRap 3D printers
written by Alessandro Ranellucci <aar\@cpan.org> - http://slic3r.org/

Usage: slic3r.pl [ OPTIONS ] [ file.stl ] [ file2.stl ] ...

    --help              Output this usage screen and exit
    --version           Output the version of Slic3r and exit
    --save <file>       Save configuration to the specified file
    --load <file>       Load configuration from the specified file. It can be used 
                        more than once to load options from multiple files.
    -o, --output <file> File to output gcode to (by default, the file will be saved
                        into the same directory as the input file using the
                        --output-filename-format to generate the filename.) If a
                        directory is specified for this option, the output will
                        be saved under that directory, and the filename will be
                        generated by --output-filename-format.
  
  Non-slicing actions (no G-code will be generated):
    --repair            Repair given STL files and save them as <name>_fixed.obj
    --cut <z>           Cut given input files at given Z (relative) and export
                        them as <name>_upper.stl and <name>_lower.stl
    --split             Split the shells contained in given STL file into several STL files
    --info              Output information about the supplied file(s) and exit
    
$j
  GUI options:
    --gui               Forces the GUI launch instead of command line slicing (if you
                        supply a model file, it will be loaded into the plater)
    --no-plater         Disable the plater tab
    --autosave <file>   Automatically export current configuration to the specified file

  Output options:
    --output-filename-format
                        Output file name format; all config options enclosed in brackets
                        will be replaced by their values, as well as [input_filename_base]
                        and [input_filename] (default: $config->{output_filename_format})
    --post-process      Generated G-code will be processed with the supplied script;
                        call this more than once to process through multiple scripts.
    --export-svg        Export a SVG file containing slices instead of G-code.
    -m, --merge         If multiple files are supplied, they will be composed into a single 
                        print rather than processed individually.

                        very little need to change this value, which is only useful to 
                        compensate for filament packing (default: $config->{extrusion_multiplier}->[0])
