RE: tag doesn't always tag

[Jacob Weber]

Todd,

I spent a lot of time trying this with diff, and eventually gave up. The
problem was that diff (even with -N) would only show changes in a directory
if I already had that directory in my working copy. But it's possible that
the directory and all its files have been deleted. In this case, I still
want to see the files that were deleted, but diff won't do anything ("no
such directory").

My overall goal is pretty simple: I want to make a script where I can pass
in an arbitrary directory and tag, and it will restore that directory to the
version with the tag, and commit it. I also would like to preview the
changes, which is where diff/rdiff comes in. The result should be that the
new version of the directory should be exactly the same as it was when it
was tagged.

Harder than it sounds!
Jacob

Jacob,
would (in a checked out sandbox)
`cvs diff -N --brief -rtag1 -r HEAD dir`
do close enough to what you want?

rdiff apparently does not have the -N option, and diff does not do the same
thing with -s
