// This script adds an "SVG" tab when editing image description pages.
// that tab adds the ShouldBeSVG template to the page with a Format
// section and submits. Written by :en:user:brighterorange. Distribute freely.

// TODO: 
// - Detect when the image is actually on Commons (how?) and don't apply then
//    (or go there and ConvertToSVG)
// - Show when just viewing an image; should edit, add message, submit
// - if a JPEG, also BadJPEG template?

// <nowiki><pre>
// maybe this stuff should be in a separate library?
