Working tree for the community fork of Songbird, Nightingale. If building, use the sb-trunk-oldxul (development) branch, with the tag 1.12.1 tag for stable, for now. The master-xul-9.0.1 branch is the current progress in building Nightingale with XULRunner 9 and builds, but is broken. All help in terms of patches and pull requests is welcome.
