Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Thanks Mike. LGTM.

Side note: It seems we require pip, but then don't use it. Should we be using pip to do the install or should we switch the requirement back to setuptools?

Edit: Raised the side note as issue ( #44 ).

shrug doesn't matter to me. More concerned with the big rebuild effort right now. Go ahead with whatever cleanup you want to do.

Thanks Mike.

Opted to just merge it (as it isn't really related to this PR). Created issue ( #44 ) to point out that pip isn't being used and try to get feedback from others/fix it at some point.
