Here are some ideas on ways you can assist the project.
One of the simplest and most effective ways you can help out is to test the Reference Build instructions as much as possible. Run test builds and report any problems to the development mailing list (if you're subscribed) or send reports directly to email@example.com . If you want to quickly get a build up and running, grab the latest gsbuild scripts for an effortless "by-the-book" experience.
If you would like to share your scripts and ideas, get in touch and we will arrange to place your work in the "contrib" area of the website.
