Many people are used to hosting multiple projects in a single
CVS repository.  Unfortunately, CVSTrac is not able to deal with
that situation.  CVSTrac requires a separate CVS repository for
each project.

_To_do: Talk about how to set up multiple CVS repositories.
Or maybe refer the user to the CVS documentation on how to do
that._

If you already have multiple projects in your CVS repository,
you will need to split it into multiple separate repositories.
How to do this is explained at CvsRepositorySplitting.
