				The Eclipse Foundation scans project Git repositories to

				various sorts of documentation that are required for governance purposes
				or are strongly recommended to help adopters and contributors acquaint
				themselves and otherwise be successful with the project.
			</p>
			<p>
				Repositories are scanned <em>nightly</em>. Changes to repositories
				may take as long as a day to be reflected here.
			</p>

				This feature is <strong>experimental</strong> and under development.
