 # mass-rename: update source files (gyp lists, #includes) to reflect
 # a rename.  Expects "git diff --cached -M" to list a bunch of renames.
 #
 # To use:
 #   1) git mv foo1 bar1; git mv foo2 bar2; etc.
 #   2) *without committing*, ./tools/git/mass-rename.sh
 #   3) look at git diff (without --cached) to see what the damage is
 #   4) commit, then use tools/sort-headers.py to fix #include ordering:
 #   for f in $(git diff --name-only origin); do ./tools/sort-headers.py $f; done
