How this about this: post-migration, I'll annotate README (the one in our
top-level directory) with all this information, plus the final record of the
revision offset caused by the load into the ASF repository. (And if I can
dig up the relevant info, I'll do a post-facto documentation of the merge of
the svn-logos/ repository data long ago, too.)
