cat smile.gcode | gsim
npm install -g gsim
Gsim can be annotated with addition information about the job with meta attribute comments.

G0 X1
G0 Y1

My hope is that other generators and simulators will adopt this convention and collaborate towards a standard.
Currently tooldiameter is the only attribute.
