SVG Round

Simple and very destructive script by Simon Pieters (see original page for extra features) for SVG file size optimization. Now in Node.js wrapper:

• Rename this script to svground, put it in /usr/local/bin/, make chmod +x svground
• Run svground file quality where file is the path to the file and quality is quality from 1 to needed number.

Sometimes it shaves off a lot of useless fractional values without any notable visual difference.
