BIG update to code, can CVS help?

[reg]

This group was able to come up with a solution to my last problem,
so Im trying again with this one.

I have a subroutine that I maintain, and I just received an 'update'
from a user.

The diff from the original to the users version goes on 40 pages (sigh).

Now its not really that bad, a good deal of this is just
    o Changes to captilisation of comments.
    o Reformatting of comments
    o Spelling errors in comments...
    o changes to a few variable names to better reflect their usage.

The rest I would like to look at more carefully.

Is there any way that CVS can help me incrementally apply this change
to the code, noting that I want to be able to compile and test at each
stage of the game?

The alternative is a lot of grunge work, which is going to take a lot
more time than I have in the near future...
