I also need to be able to pull out all the file from version x. I suspect there is an easy way to do this, but it has escaped me so far.
CVS manages revision numbers on individual files. Some version control
systems manage version numbers on sets of files (Git, Mercurial?).
Still others number both individual files and sets of files (MKS SI).
But, CVS provides "tags" for working with sets of files:
info cvs
cvs --help tag
You can see the tags on a particular file with:
cvs log FILENAME
When I want to create a release of one of my projects, say revision
1.108, I check in all the files and then run:
cvs tag -c r1_108
This applies the tag "r1_108" to the current revision of the files in
the working set. (The -c option ensures that they are checked in, to
reduce operator errors.)
If I later want to check out all the files from a particular release:
cvs co -r r1_108
(Note that CVS will mark the files as "sticky", which adds complexities
I avoid by not editing them.)
CVS also has the ability to check out files by date, but I have never
tried that. If your files don't have tags, perhaps you can check them
out by date and then add tags. Be sure to back up your CVS repository
before mucking about.

p.s. I learned CVS from an earlier version of this book. The current
edition (3 e.) is available as a PDF download:
