-	  configuration found at /data/misc/wireguard/INTERFACE.conf. It is to be readable
-	  by wg(8)'s \`setconf' sub-command, with the exception of the following additions
-	  to the [Interface] section, which are handled by $PROGRAM:
-
-	  - Address: may be specified one or more times and contains one or more
-	    IP addresses (with an optional CIDR mask) to be set for the interface.
-	  - MTU: an optional MTU for the interface; if unspecified, auto-calculated.
-	  - DNS: an optional DNS server to use while the device is up.

-	See wg-quick(8) for more info and examples.
