Edit: I moved the script to GitHub, go there for full information and downloads.
This script converts an Inkscape SVG to Adobe Illustrator 7 compatible EPS. The generated EPS file uses custom Illustrator PS operators, and includes PostScript processes that stands in place of said operators when the file is not opened with Adobe Illustrator.
Please report issues using the project’s github issue tracker, and upload a minimal SVG file that can reproduce the error.
If you create some graphics and export it with this script, the copyright of the exported image belongs to you, your are free to do with it whatever you want.
