Reduce file size of eps image file in Linux (eg., during arXiv submission)

It's not clear how to do this within Inkscape (even if you are creating your eps in Inkscape)

So, open the file in Gimp. Choose resolution 100 (default).

Then export to eps in Gimp. This should create a much smaller file already.

Tradeoff compactness and quality by adjusting resolution at the time of loading the eps into Gimp.
