[cvsnt] Newbie Question about cvswrappers and similar files

[Berkley, Donna -CIV]

Just double-checking how this works before I do something stupid ...
 
I just set up a cvs server using sspi and a successfully logged into it with a client.   I am now considering fine tuning options.   I want to customize the server by making modifications to files like cvswrappers.    I notice that there are three versions of it in the CVSROOT.    
 
.#cvswrappers
cvswrappers
cvswrappers, v
 
I know that the "cvswrappers, v" is the source file that I will need to check out, modify and check back in.   That does not, however, put my changes to the server in place to "take affect", correct ?   I assume that one of the other two files is the one that requires editing/replacing to make my changes effective.
 
Can someone tell me what the difference is between these two files ?   I have not come across that information anywhere yet.
 
Thanks.
