I said it isn't a big issue because at this point you have decided to move from
ClearCase to CVS. The metadata issue, the SCM process impact issue discussion
is long since past. Hyperlinks, atrributes, etc... they don't exist in CVS. If
this where a big issue, one would not have gotten to the point of 'I need to
convert from Clearcase to CVS, what's the best way to do it'.

Of course, I could be getting ahead of myself here, if there is a reasonable
and workable way to convert ClearCase metadata and put it into CVS in a
usable/benefitial way. I am more that happy to hear about it.

I just wanted to explain how the directory versioning could impact/affect a
ClearCase to CVS conversion effort. We are on the same page here.

As I said in my original response, that the best thing might be to just perform
cvs imports on milestone and important baselines from ClearCase, and not try to
convert the whole ClearCase repository, maintaining all history and file
