Release on xELPA

[Norbert Melzer]

Currently, mix.el is not available through MELPA. If there is a demand for it, I'll upload the package there.

Please do, as installing from xELPA is a lot easier than from source when doing declarative package management on nixOS.

[Ayrat Badykov]

I'll submit this package to MELPA in 10 hours in the morning in my timezone
