You may want to get an infrastructure person or someone who's written a bunch of
python in chromium to see if there's a better way to do this.

phajdan would be a great candidate, especially since he wrote licenses.py

[mef, 2014/05/19 21:38:03]

Sounds good. I've copied this pattern from webview_licenses.py. Pavel, do you
have any suggestions?

Nit: extra newline

Done.

Nit: Two blank lines required before top-level definition.

There's a couple other cases like that throughout this file.

Probably should do the f.close() in a finally: block wrapping a try: around
