I went and looked at the Lucene directory on the master mirror site https://www.apache.org/dist/lucene/
and it seems to already have been swapped out for the SVN dist dir. - I can see that the releases have been pared down to the minimum there, as in SVN.
The Lucene and Solr 4.1 RC1 VOTE passed - I'm going to start committing the release packages.
Is there anything else that needs to be done here?
