I don't know. How do I translate

pip install hg+ssh://hg@bitbucket.org/cghub/cghub-cloud-agent@default

with cghub-cloud-agent's setup.py being

        'cghub-python-lib>=1.4.dev1', ...
hg at bitbucket.org/cghub/cghub-python-lib at default#egg=cghub-python-lib-1.4.dev1
hg at bitbucket.org/cghub/cghub-cloud-lib at default#egg=cghub-cloud-lib-1.0.dev1'

into a use of --find-links?
