Hmmm. Let me see if I understand this.

Typing the command

        cvs update -r HEAD file.c

will cause the following behavior (until the sticky tag is changed):

        1. Updating file.c from the repository will always work.
        2. Committing a changed file.c to the repository will never work.

So, how would I use it? For example, suppose I need to add some temporary code to a file for debugging or to make some kind of measurement. If I "update -r HEAD" then I can prevent the temporary code from accidently polluting the repository. When I'm done, remove the file and "update -A" (assuming there were no changes of value in the file).
