This is a program to take an SVG file and cut it using Drufel on the
Sainsmart MX3 CNC.

It produces a file similar to the "Sainsmart.nc" demo that comes with
the device.

The changes to the original svg2gcode program from which it is derived
( https://github.com/holgafreak/svg2gcode ) are minor - mainly just
changing defaults to suit the MX3 and simplifying the command line options
so that few are needed.

Usually "-w width" is sufficient - that one rescales the drawing to have
a max width of the number given in mm.  For example the test image of
the YouTube logo is quite large so I test it using "-w 30" to reduce it
to a 3cm width.

The software does *not* do filling or rasters.  It simply draws the lines
present in an SVG file.  This is useful for some projects and not for others,
so add it to your kit of tools for when you can use it.

In my case, I'm engraving images on scratchboard, so for me it is ready to
use :-)
