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

I wanted to let you know that I linted all conda-recipes in your PR (recipe/recipe.yaml, recipe/meta.yaml) and found some lint.

Here's what I've got...

For recipe/recipe.yaml:

• ❌ Recipe folder contains both meta.yaml and recipe.yaml. Only one recipe file at a time is allowed.

For recipe/meta.yaml:

• ❌ Recipe folder contains both meta.yaml and recipe.yaml. Only one recipe file at a time is allowed.
