'''
The **urls** utils module offers a replacement for the urllib2 python library.

urllib2 is the python stdlib way to retrieve files from the Internet but it
lacks some security features (around verifying SSL certificates) that users
should care about in most situations. Using the functions in this module corrects
deficiencies in the urllib2 module wherever possible.

There are also third-party libraries (for instance, requests) which can be used
to replace urllib2 with a more secure library. However, all third party libraries
require that the library be installed on the managed machine. That is an extra step
for users making use of a module. If possible, avoid third party libraries by using
this code instead.
