 Shows current WireGuard configuration of specified \fI<interface>\fP.
 If no \fI<interface>\fP is specified, \fI<interface>\fP defaults to \fIall\fP.
 If \fIinterfaces\fP is specified, prints a list of all WireGuard interfaces,
 one per line, and quit. If no options are given after the interface
 specification, then prints a list of all attributes in a visually pleasing way
 meant for the terminal. Otherwise, prints specified information grouped by
-newlines and tabs, meant to be used in scripts.
+newlines and tabs, meant to be used in scripts. For this script-friendly display,
+if \fIall\fP is specified, then the first field for all categories of information
+is the interface name. If \fPdump\fP is specified, then several lines are printed;
+the first contains in order separated by tab: private-key, public-key, preshared-key,
+listen-port, fwmark. Subsequent lines are printed for each peer and contain in order
+separated by tab: public-key, endpoint, allowed-ips, latest-handshake, transfer-rx,
+transfer-tx, persistent-keepalive.
