On the machine with the CVS repository, I ran:
cvs2svn --default-eol=native --dumpfile clean.dump [cvsroot]/clean2
and then on the server with the SVN repository, I ran:
svnadmin load [svnroot] < clean.dump
This promoted a single project within the CVS repository to be the main line of a new SVN repository. Which seemed like the thing to do, since the 60Hz projects are pretty loosely coupled.
