for example,
create some project with src root
checkout some package from cvs into src directory
enable cvs for the project
all the files located in the project directory itself (project files always) appear as Unversioned files in the changes list.
Note that the project directory itself that contains these files doesn't contain CVS subfolder
now add some files to versioned packages
invoke AddToCVS for all Unversioned list — cvs fails since it cannot find admin files in the top folder, and all the files from the project appear in unversioned list since the admin files are removed from all folders in project.
