+	out the series and look in patchwork for the resulting series. The
+	URL you want is the one for the series itself, not any particular patch.
+	E.g. for http://patchwork.ozlabs.org/project/uboot/list/?series=187331
+	the series ID is 187331. This property can have a list of series IDs,

+	Patman always uses the one without a version, since it assumes this is

+	branch against patchwork to see what new reviews your series has
