reflinks.py is one of the few scripts still using urllib2. It should be possible to achieve the same functionality using [[http://docs.python-requests.org/en/latest/|requests]].
Before attempting to switch to requests, the current usage of urllib2 should be analysed to map it to requests functionality (assuming requests has the same functionality -- it might not!).
e.g. reflinks currently only fetches 1000000 bytes from each webpage. requests does have the ability to read only a small amount of a webpage. (to be investigated further)
