sync
====
[`sync`](https://skia.googlesource.com/skia.git/+/master/bin/sync)
is a Python program that wraps `tools/git-sync-deps`. Motivations for using it:
- Written in Python, so it will work on all platforms.
- Checks to see if the `DEPS` file has changed since it last ran
`gclient sync`. If not, it skips that step.
- Since running `sync` is fast when it can do nothing, it is
easy to do before every recompile of Skia. This is a good habit.
