#Delete Old Nodes
This will clean out nodes which have not been seen longer than the value of `$oldenough` - I've set this to one month.

I keep my api key in ~/keys/tailnetname.api.key - if you have them elsewhere, you should change the `$apikey` value.

And set `$tailnet` to the domain of your tailnet.
