+Check that the current sourcemap and worker bundles built for DevTools are up to date.
+This job should fail if any file impacting the bundle creation was modified without
+regenerating the bundles.
+
+This check should be run after building the bundles via:
+cd devtools/client/debugger
+yarn && node bin/bundle.js
+
+Those steps are done in the devtools-verify-bundle job, prior to calling this script.
+The script will only run `hg status devtools/` and check that no change is detected by
+mercurial.
