-google-java-format Diff Reformatter
-============================
-
-This script reads input from a unified diff and reformats all the changed
-lines. This is useful to reformat all the lines touched by a specific patch.
-Example usage for git/svn users:
-
-  git diff -U0 HEAD^ | google-java-format-diff.py -p1 -i
-  svn diff --diff-cmd=diff -x-U0 | google-java-format-diff.py -i
-
-For perforce users:
-
-  P4DIFF="git --no-pager diff --no-index" p4 diff | ./google-java-format-diff.py -i -p7
