       jsurf-alggeo - Java based renderer for real SURFaces (ALGebraic
       GEOmetry dedicated tool)

       usage: jsurf-alggeo [options...] {jsurf_input|-} [png_output|-]

       jsurf-alggeo is a renderer for real algebraic surfaces.  jsurf-alggeo
       translates its own language script files (generally with extension
       '.jsurf') into Portable Network Graphics (PNG) files; PNG is a raster
       graphics file format that supports lossless data compression.  If the
       output filename is not specified, the output is placed in a file of the
       same basename with a '.png' extension in the current working directory.
       Either the input filename or the output filename can be '-' to request
       reading from stdin or writing to stdout, respectively. Whenever the
       Graphic Unit Interface (GUI) is available, the gui option takes
       precedence over the output options, otherwise it is ignored. That is,
       whenever the gui option is present (and available), the output is
       displayed in a window rather than written to a PNG file.

       --gui  display rendering (overrides output options)

       --help display this help text and exit

       -o,--output <arg>
              output PNG into this file (overrode by the 2nd argument if

       -q,--quality <arg>
              quality of the rendering: 0 (low), 1 (medium, default), 2
              (high), 3 (extreme)

       -s,--size <arg>
              image width and height (default: 512)

              print program version and exit
