vPerms is a real time permission system utilizting vDiscord. The script is event based, meaning that it allows for real-time permission updates (no need for relogging or restarting the server for perms to update!). The perms are based on discord roles. This is a rewritten version of sPerms, made by SpaceTheDev (forums, github).
