CVS vs ClearCase, was RE: cvs -n update vs cvs diff

How should a working directory be used? What should
be done within it, and what should be done in a 
separate working directory?

And how should the status of the files within one's
working directory be determined?

I'm used to ClearCase, where a person worked within a
dynamic view and you could build, label (tag), branch,
merge and do everything within the same workspace.

How does CVS differ from that model?

It would really help me out if somebody could provide
some direction on this. I keep stumbling over the
differences between how CVS and ClearCase handles these

That would more properly be "cvs -H diff", btw, as per the message from
"cvs -?":

    (specify -H followed by a command name for command-specific help)

That would suggest then that your users are working under some nearly
fundamental misconceptions about how a working directory is used and how
the status of the files within it can be determined.  I don't think
adding more info to the usage message would help override their
misconceptions.  You'll have to fix this problem at its root.

It may also suggest that your users are not really very aware of what
the rest of their team might be doing too, and that's another problem
best solved at the root where it starts....  :-)
