Conan-center-index: [question] Library with no license

[ericriff]

Hi, I'm creating a recipe for easylzma which has no license file. The readme says that is Public Domain, so that's what I put on the license field of the recipe.
The issue lays on the conan-center hook, it marks as an error the fact that I'm not including a license file on the package. Should I export that readme as license or maybe create a file that says this library is public domain or something like that?

Thanks.

Maybe a file with this extract from the readme?

All the cruft you find here is public domain. You don't have to credit
anyone to use this code, but my personal request is that you mention
Igor Pavlov for his hard, high quality work.

Copying over these few lines should be fine IMHO
