Documentation for supported [sources] keys #4209
Description
For completeness, it would be nice if the documentation for [sources] specified which keys can be used, i.e. url, rev, etc., and what their value means. Currently you need to deduce this from the example snippet, but it leaves me wondering if other keys like version are supported.
