 1 | svg2gcode
 2 | ========
 3 | A command line utility for converting SVG to Gcode using [Gcanvas](https://github.com/em/gcanvas) and [canvg](https://code.google.com/p/canvg/).
 4 | 
 5 | ### Installation
 6 | First make sure you have [nodejs](http://nodejs.org) installed.
 7 | ```
 8 | npm install -g svg2gcode
 9 | ```
10 | 
11 | ### Usage
12 | ```
13 |   Usage: svg2gcode [options] <file ...>
14 | 
15 |   Options:
16 | 
17 |     -h, --help                 output usage information
18 |     -V, --version              output the version number
19 |     -s, --speed <number>       spindle speed
20 |     -f, --feed <number>        feed rate
21 |     -d, --depth <number>       z of final cut depth
22 |     -c, --depthofcut <number>  z offset of layered cuts
23 |     -t, --top <number>         z of top of work surface
24 |     -a, --above <number>       z of safe area above the work
