+ * Runs tasks for pre-commit, including lint and qunit testing.  Avoids the overhead of grunt and Gruntfile.js for speed

+ * USAGE:
+ * cd ${repo}
+ * node ../perennial/js/scripts/hook-pre-commit.js
+ *
+ * OPTIONS:
+ * --console: outputs information to the console for debugging
+ *
+ * See also phet-info/git-template-dir/hooks/pre-commit for how this is used in precommit hooks.
