So, you're probably confused as to what this is. Well, it's a proxy for puush. The developers for puush decided to be all stupid and refused to implement useless features like SFTP and FTP.
So, my absolutely brilliant friend @jannispl decided to write a new proxy for puush in node.js. This, as far as we know, was the first alternative implementation of puush.
This is basically abandoned, and will likely never be updated again.
If you're using it, please let me know. I would be very curious to find out if anyone is still using it.
Unless you genuinely need to use this package, please find something else.
