Copying the history file
========================

   This way also involves direct modifications to the repository.  It
is safe, but not without drawbacks.

     # Copy the RCS file inside the repository
     $ cd $CVSROOT/MODULE
     $ cp OLD,v NEW,v
     # Remove the old file
     $ cd ~/MODULE
     $ rm OLD
     $ cvs remove OLD
     $ cvs commit OLD
     # Remove all tags from NEW
     $ cvs update NEW
     $ cvs log NEW             # Remember the non-branch tag names
     $ cvs tag -d TAG1 NEW
     $ cvs tag -d TAG2 NEW
     ...

   By removing the tags you will be able to check out old revisions of
the module.

Advantages:

   * Checking out old revisions works correctly, as long as you use
     `-rTAG' and not `-DDATE' to retrieve the revisions.

   * The log of changes is maintained intact.

   * The revision numbers are not affected.

Disadvantages:

   * You cannot easily see the history of the file across the rename.
