+/* NAME
+/* tok822_resolve 3
+/* SUMMARY
+/* address resolving, client interface
+/* SYNOPSIS
+/* #include <tok822.h>
+/*
+/* void tok822_resolve(addr, reply)
+/* TOK822 *addr;
+/* RESOLVE_REPLY *reply;
+/*
+/* void tok822_resolve_from(sender, addr, reply)
+/* const char *sender;
+/* TOK822 *addr;
+/* RESOLVE_REPLY *reply;
+/* DESCRIPTION
+/* tok822_resolve() takes an address token tree and finds out the
+/* transport to deliver via, the next-hop host on that transport,
+/* and the recipient relative to that host.
+/*
+/* tok822_resolve_from() allows the caller to specify sender context
+/* that will be used to look up sender-dependent relayhost information.
+/* SEE ALSO
