I think there should be some vertical space here. The style guide doesn't seem
to be explicit, but I've been doing 1 blank line before the first import and two
after the last.

+def _SetupTVCMPath():

_SetupTVCMPath -> _SetupTvcmPath

+  tvcm_path = os.path.abspath(os.path.join(
+      os.path.dirname(__file__),
+      '..', '..', '..', '..',
+      'third_party', 'trace-viewer', 'third_party', 'tvcm'))
+  assert os.path.exists(os.path.join(tvcm_path, 'tvcm', '__init__.py'))
+  if tvcm_path not in sys.path:
+    sys.path.append(tvcm_path)

I think we also have a util method that appends to the path.
