Thanks for the tip, and as I'm new to Subversion
many thanks to all who give there time to it;
I am planning on migrating an existing CVS repository to svn
(using cvs2svn) and I thought I might try this tip
to (hopefully) speed up the job.

Am I correct in assuming that after an import/migration
one could re-enable this for everyday use?

<OffTopic cvs2svn>
   BTW, if anyone here has experience of cvs2svn,
   I had to make some changes to get it to work for me;
   I posted a question to the cvs2svn list but there
   doesn't seem to be any traffic on that list...?

Thanks again,

Richard Meade
