To generate the log used for input:

  $> grep -v '^#' openstack-config/essex | \
      while read project revisions; do \
       (cd ~/git/openstack/$project; \
        git fetch origin 2>/dev/null; \
        git log --no-merges --numstat -M --find-copies-harder $revisions); \
      done > log.txt

I then manually deleted the translation imports from the
'OpenStack Jenkins' user.

The EmailAliases file was created with this horror:

  $> for p in nova glance swift horizon; do cat ~/git/openstack/$p/.mailmap; done | \
      grep -v '^#' | sed 's/^[^<]*<\([^>]*\)>/\1/' | \
      grep '<.*>' | sed -e 's/[<>]/ /g' | \
      awk '{if ($3 != "") { print $3" "$1 } else {print $2" "$1}}' | \
      sort | uniq > aliases

with the only exception that I've tweaked Soren's canonical
email address to be is linux2go one, to fix a git-dm traceback.

To generate the stats I did:

  $> python ./gitdm -l 20 -n < log.txt
