At the end of each conversion, my script does a cvs export of cvs HEAD
and a git-checkout-index (equivalent of cvs export) and runs a
recursive diff on the two directories.  I thought about doing this for
every branch head too, but I that's going overboard.  Maybe doing it
for the 1.0.0 and 1.1.0 branches would be worthwhile.

As Daniel mentions, git checkout master as mentioned on the migration
page doesn't actually work as suggested.  git reset --hard does, or as
I'm doing in the script:

    git-read-tree master
    git-checkout-index -a --prefix=git-checkout/

This gives the expected results and so does a git clone of the newly
created repository.  On all the repositories I test-converted, I
didn't get any differences from the recursive diff check.

cheers,
