  Description     : Run any Windows program through Proton

I've been maintaining this package and uploading it onto the program's GitHub releases page since version 2.2.2.
I'm interested in getting this package into Debian so that it can just be installed via apt instead of needing to download a stray deb file.
The only thing this package depends on is Steam, which is outside the Debian distribution, so this package should go into contrib.
