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.

I do have some suggestions for making it better though...

For recipe:

• License is not an SPDX identifier (or a custom LicenseRef) nor an SPDX license expression.

Documentation on acceptable licenses can be found here.

Nice, thanks!

Jeremy, do you want to add yourself as a maintainer as well?

[jtpio]

Looks like that already the case on master and is enough to also be able to merge on other branch like dev here.
