checkout ontop of otherwise installed source

[Brian Hughes]

Hi.

If I have installed something from a tarball (it's a web app, a bunch of 
php mostly) and then I do a checkout ontop of it, will CVS work right?

The context is I am envisaging distributing something as a tarball, and 
then later those who like the app and wanted to develop it would get a CVS 
account and do the checkout into the same directory tree as they created 
with the tarball.
