RE: Is this possible? <More Info>

Sorry Jerry and others for not being clear:

I need to tag or label a specific version of a specific file perhaps days 
after other versions have been put in the repository.

I need to pass this info over to another system, perhaps the problem 
reporting tool or the project management tool:

     PR# 321 was solved by adding foo.c version 3.2.1 and foo.h version 
3.3.1. These now have the tag REL3.2 (This implies that if I checkout all 
the files using tag REL3.2, I can build the entire product.)

I want to get the name of the individual commiting the change, and the 
version of the file commited. The file version information would be used, 
maybe several days later, after it was approved to go in a build. To go in 
a build, the file that was approved would be labeled/tagged with the build 
label and a co would be issued against files with that label. In other 
words, I am using tags to create baselines for builds. These tags are 
applied against individual files after said files are approved. Typically, 
a group or list of files is associated with a problem report or change 
request and when that change request is approved, those files associated 
with it are tagged/added to the build. Good solid CM. Problem is that while 
the foo.c version 3.2.1 fixes problem 321, foo.c may need to be modified 
again to fix problem 333. So, after 321 is fixed and still in the approval 
cycle, 333 may go to the developer for work.
    In some CM systems, we have seen build systems where a developer gets 
up on a chair and says, "OK, Everybody check in everything for tonights 
build". There is no control here. No one knows why a change is being 
committed. How do you pass the changes over to QA? A change history 
generated by CVS is not necessarily clear and does not insure that other 
parts of the process are completed. For instance, has the PR been passed on.
