Grails, documentation and images

A quick tip of the day:

if you're creating a Grails project and want to provide documentation for it it might stand a chance you'll need to include images in that documentation. Unfortunately the official documentation is very sparse in this regard showing you only the syntax for including external images. As it turns out it is possible to have images that come specifically with the docs. All you need is to specify

grails.doc.images = new File("src/docs/images")

and then include them in the docs as usual but without a URL

!my-image.png!

Thanks to Lauro Becker for that hint!
