## Getting Sphinx to execute the previous list of tests

Current efforts of first finding the files lead me to

/binjitsu/pwnlib which contain .py and .pyc
/binjitsu/docs/source which contain .rst
/binjitsu/docs/build/doctree which contain .doctree

Attempt to include missing test include

sphinx-quickstart with --ext-doctest extension
sphinx-build
sys.path update to include '/binjitsu/pwnlib'

all of which have yet to yield the desired results.
