This is a copy of the famous silk icons, created by Mark James, Birmingham, UK. It is intented to be used as git submodule.
There are plenty of projects using the silk icon set. Most developers simply put a copy of the silk icon set into their repository, wasting space. Using the silk icons as git submodule is more elegant and keeps your main repository pollution-free. As a bonus, you can fork and commit your own icons - and eventually merge them back.
You may use the icon set under either the [Creative Commons Attribution 2.5]http://creativecommons.org/licenses/by/2.5/ or the [Creative Commons Attribution 3.0]http://creativecommons.org/licenses/by/3.0/ license.
