-# Gcode Interpreter
-
-Extracted [from
-octoprint](https://raw.githubusercontent.com/OctoPrint/OctoPrint/master/src/octoprint/util/gcodeInterpreter.py), this
-package provides static analysis (ahem. abstract interpretation) of GCODE scripts for 3d printers to provide key data
-such as the bounding box through which the tool(s) move, estimated net movement time and the net amount of material
-extruded.
