Can we ad a TODO to not have a dependency here if we land this as-is?

Where will this eventually go, out of curiosity?

[tonyg, 2012/09/25 17:29:29]

Added TODO to sort this out. 

+sys.path.append(
+    os.path.abspath(
+        os.path.join(os.path.dirname(__file__),
+                     '../../../chrome/test/functional')))
+import webpagereplay

+CHROME_FLAGS = webpagereplay.CHROME_FLAGS

Ah, I had forgotten is that in replay mode you need to start chrome up with
args. Do you still think that the page_runner infrastructure is the right way to
do this?

[tonyg, 2012/09/25 17:29:29]

yeah, page_runner worked well with the addition of browser_extra_args to
Create().
