I'd like to mention a bit from the "literature on the svn website"...
Here's a citation I like:
"While CVS and Subversion are still primarily copy-modify-merge systems,
they both recognize the need
to lock an occasional file and provide mechanisms for this. See the
section called 'Locking'
<http://svnbook.red-bean.com/nightly/en/svn.advanced.locking.html>."
(http://svnbook.red-bean.com/nightly/en/svn.basic.vsn-models.html, the
last bit of the page...)
So, the "copy-modify-merge" vs "locking" is not an issue when you
compare CVS and SVN.
