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 (recipes/graphene-tornado) and found it was in an excellent condition.

Added an issue there to tell the maintainers about the recipe being published here too: graphql-python/graphene-tornado#35

Here's what else I did locally when creating this recipe:

• python setup.py sdist the graphene-tornado module, and confirmed there is a LICENSE file inside the source file
• conda build . in the recipe folder, then conda install --use-local graphene-tornado, confirmed in the console output it was being installed from ~/anaconda3/conda-bld/...; then import graphene_tornado

We were using a similar recipe in a private channel to test out system that uses graphene-tornado: https://github.com/cylc/cylc-conda/blob/c4b692f5d9ba949b4005b1f390c498df3b62e758/recipes/graphene-tornado/meta.yaml

Oh, while testing locally, conda build . failed without the pytest dependency under host.
