Ignore local changes?

[Wade Williams]

I've got a file which I must make changes to on my system.  However, I 
don't ever want my changes put back into the repository.

Currently, I handle this by removing the file and re-updating the file 
from the repository before doing a commit.

But is there a way I can tell CVS - always update this file on an 
update, but ignore my changes on a commit?

Thanks,

Wade
