+<h1> Real-time read-only svn mirrors </h1>
+<p>
+These repositories are mirroring the master repo in real-time. That means
+seconds after a commit to the master repository the synchronization takes
+place and the mirror should be up to date. Use these mirrors if you
+never commit and the master repository feels slow.

+<h1> Periodic read-only svn mirrors </h1>
+<p>
+These mirrors upgrade periodically, thus they are lagging behind the main
+repositories above. Do not use them unless none of the above repositries
+are accessible.
