Makefile

# Copyright (c) 2019 Brad Tarratt

# Purpose:
# This makefile simply runs a command with Inkscape to convert a file from svg to
# eps, and then runs another command with pstoedit to convert it from eps to
# dxf.  You can easily convert a whole directory with "make", or just one file
# with "make something.dxf".  Make will only convert SVG files that are newer
# than their DXF counterparts (or if the DXF is not yet made).

# Requirements:
# You will need to install Inkscape, pstoedit and gmake and make sure they are
# added to your PATH. On most linux distributions you should be able to use apt
# or similar to install the packages, on MacOSX you may need to use something
# like ports to install pstoedit then manually add the PATH.
