Drivers 1.7.5 RC2 with Slic3r Prusa Edition (Updated 18 Nov)  

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, --threads <num> Number of threads to use (1+, default: 2)

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
--gui-mode Overrides the configured mode (simple/expert)
--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: [input_filename_base].gcode)
--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.

print rather than processed individually.
