My question was more whether it made sense to provide two different
packages, if they both have the same files. Does the `conda` executable
from 'python-conda' work differently? Maybe we should rename or remove
it to avoid conflicts?

Great, thanks!

Ahh okay. Having read both scripts it looks like 'setup.py' only
installs "conda.cli.pip_warning:main" instead of the real thing. Sorry
for the confusion!

Sounds good. I still think it's worth investigating if this "official"
(quotes since it's still explicitly unsupported) build method also can
be used as a library so we can avoid maintaining three variants of
nearly the same package. Let us know what you find :-)

Thanks!
