| # 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 |

| # rename: |
| # update all uses of |from| (first argument) to |to| (second argument). |
