Written to prove a point. ☺
PSVUNT stands for PlingStore Version Update Notification Tool. It is intended as a proof of concept for an update notifier. Because I don't have access to the Store source code, this works by monitoring what Store does.
Because as numerous people will tell you, Store is quite capable of telling you what has been updated in the "My software..." menu entry, WHICH IS ONLY AVAILABLE ONCE YOU HAVE SIGNED INTO STORE.
This is retarded - whether or not something is "new" should depend purely on whether or not it is new, not upon whether or not you're connected to the mothership.
So this module, hacked together one sunny Sunday, is a proof of concept to demonstrate this fact while also being useful for me to, well, notify me of updates. Arguably that's Store's job, but...
PSVUNT is licenced under the EUPL v1.1. You can read the EUPL here.
