Guide and examples

    permission: "ranks.give"

        send "&a%arg.1% can fly for an hour."

Syntax	Effect
`grant <who> permission <node>`	Give a player one permission, for good
`grant <who> permission <node> for <duration>`	The same for a limited time; LuckPerms takes it away again
`revoke permission <node> from <who>`	Take a permission back

As with groups, <who> may be a player who is offline, and a new time limit replaces an old one.
These are saved by LuckPerms. HyperScript's own permission <who> add <node> is a different thing: it lasts until the player leaves and is not saved.
