Licensing?

[elfatherbrown]

Hello @hrbrmstr,
Thank you for your package. It produces very pleasing plots, and I am for sure using it and also modifying it to fit my needs. I do need to ask you, because your license file only lists your copyright notice, if there could be a way to integrate it with my modifications in GPL/MIT or otherwise open source licensed software. In sum, I wanted to ask you if you think you can or want to release it with an open source license file.

Thank you for your time. I'm pretty sure you are a very busy guy.
