Point SVN Externals at a CVS Repository

Question

Is it possible to point an SVN Externals directive at a CVS repository?

Answer 1

No, it is not possible.

SVN externals simply does an checkout or update on the repository path you give it. Which doesn't support CVS.

The only thing you should point at CVS is a gun.. or cvs2svn. Long live SVN!
