Ok, let me explain further. Repository access should now be necessary if
you're not going to use version management functions (I'll add this to the
document). As soon as you're going to use some multiuser or version
features you *shall* need the single repository to be able to synchronize
Setting local only cvs repository is the matter of running 'cvs --init' and

I've tried to explain this in the following:

I think it would help us to agree fully with each other if we will
substitute every use of 'CVS' with 'version management tool', won't it?

You'll be working with your FreeCASE application, which will access
FreeCASE Repository. You shouldn't even know that there is CM repository
somewhere. The exact choise of CM tool will be made by FreeCASE Rep
admin. Some common cases (like CVS repository) could be prepackaged.

Well, by the moment, the I'm the only live being in my team ;) Guess, this
is the matter of laying out version management guidelines _before_ giving
access to the repository.
