+"""
+To update ANGLE in Gecko, use Windows with git-bash, and setup depot_tools, python2, and
+python3. Because depot_tools expects `python` to be `python2` (shame!), python2 must come
+before python3 in your path.
+
+Upstream: https://chromium.googlesource.com/angle/angle
+
+Our repo: https://github.com/mozilla/angle
+It has branches like 'firefox-60' which is the branch we use for pulling into
+Gecko with this script.
+
+This script leaves a record of the merge-base and cherry-picks that we pull into
+Gecko. (gfx/angle/cherries.log)
+
+ANGLE<->Chrome version mappings are here: https://omahaproxy.appspot.com/
+An easy choice is to grab Chrome's Beta's ANGLE branch.
+
+## Usage
+
+Prepare your env:
+
+* If in `cmd`:
+    `export PATH="$PATH:/path/to/depot_tools"`
+* If in `powershell`:
+    `$env:Path += ";C:\path\to\depot_tools"`
+
+If this is a new repo, don't forget:
+
+~~~
+# In the angle repo:
+./scripts/bootstrap.py
+gclient sync
+~~~
+
+Update: (in the angle repo)
+
+~~~
+# In the angle repo:
+/path/to/gecko/gfx/angle/update-angle.py origin
+git push moz # Push the firefox-XX branch to github.com/mozilla/angle
+~~~~
