+Since I publish a lot of [[Git]] packages, I was interested to read
+about [Joey Hess][]' [rel=vcs-* microformat][format]. I think
+recording the location of the repo sorcing a page is a great idea, but
+with the link stashed in the page header, I could easily browse on by
+without ever noticing that the link existed.
+
+This looks like the same sort of problem that the [Semantic Radar][SR]
+extension was designed to solve, except the SR extension notifies you
+about RDF files (SIOC, FOAF, DOAP, etc.). I've altered the SR
+extension to identify the `rel=vcs-*` tags.
+
+The [[rel-vcs|rel-vcs.xpi]] extension places an icon in your Firefox
+statusbar which goes "hot" when a page has `rel=vcs-*` tags and "cold"
+otherwise. When the icon is "hot", you can click on it to pop up a
+list of rel-vcs links. Clicking on an item in the list will open that
+URI in a new tab. Since Firefox can't speak `git://` etc., the new
+tab will mostly be useful as a source of the URI for copy/pasting into
+a `git clone ...` call or similar. Alternatively, you can consider
+the "hot" icon as a suggestion to use `webcheckout` or other
+`rel=vcs-*` consumer on the source page.

+Firefox extension adding a notification icon for pages with
+`rel=vcs-*` tags. See the [specs][] for details on the format.
+
+When the icon is "hot", you can click on it to pop up a list of
+rel-vcs links. Clicking on an item in the list will open that URI in
+a new tab. Since Firefox can't speak `git://` etc., the new tab will
+mostly be useful as a source of the URI for copy/pasting into a `git
+clone ...` call or similar. Alternatively, you can consider the "hot"
+icon as a suggestion to use `webcheckout` or other `rel=vcs-*`
+consumer on the source page.
+
+This plugin was initially based on the source for the [Semantic
+Radar][SR] plugin.
