The above library extracts module info from Sphinx objects.inv
database https://docs.python.org/2.7/objects.inv which is some
binary format and requires local parsing.

Ideally, the Sphinx should give out the open data about stdlib
structure, such as :
https://docs.python.org/2.7/dataset/1.0/modules.json
https://docs.python.org/2.7/dataset/1.0/modules.csv
  list all module names, sorted by name

Then you can easily load this data into web app or use it as a
table for analysis. http://www.w3.org/2013/csvw/wiki/Main_Page
