Your claim is not correct.  Directories CAN be versioned, even using an
underlying shared, file-based repository system, even if it uses RCS.
The useful metadata, as I said above, are the mappings between the working
copies of the files and their history containers, and the versions selected.
CVS embodies the mappings using the CVS/Repository file; actually it maps
the user's directory to its counterpart in the repository and then uses
a computation to complete the mapping to the actual history container.
The versions selected are stored by CVS in the CVS/Entries file.

This simple concept is invariant in all source control systems that I have
used, whether the metadata are stored in the workspace (like CVS does) or
in a database (like ClearCase does).

There's other useful stuff that could be stored about directories, but
this is the minimal set.  CVS offers a solution, but it's incomplete,
which is why this subject keeps coming up.

Nope, there's no confusion of the concepts; just griping about the
