GNOME Shell Sass is a project intended to allow the sharing of the theme sources in sass between gnome-shell and other projects like gnome-shell-extensions.
Any changes should be done in the GNOME Shell subtree and not the stand-alone gnome-shell-sass repository. They will then be synchronized periodically before releases.
GNOME Shell Sass is distributed under the terms of the GNU General Public License, version 2 or later. See the COPYING file for details.
