automated rollback tag

[Shawn Matlock]

CVS version 1.11.17

I'm trying to work out a method to create a rollback tag.

File_A
        HEAD            1.1
      RC1               1.1
      RELEASE   1.1

File_B
        HEAD            1.2
        RC1             1.1
      RC2               1.2
      RELEASE   1.2
      RC3               1.4

File_L
      HEAD              1.1
      RC2               1.1
      RELEASE   1.1

File_M
        HEAD            1.1
      RC3               1.1

RELEASE is applied to all files currently released.
        
RC3 has not been released.

I want to create a rollback tag specifically for RC3 (RC3_rollback). It should 
be applied to the same revision as RELEASE only for the RC3 files that exist in 
RELEASE.

My solution is to create a Perl script:
        1. check out the RC3 tag
        2. *individually* update each file to RELEASE <-- slow/painful
        3. tag all the working copy with RC3_rollback

Is there a better solution to this? 

Thanks,
Shawn Matlock
