%% An example Diameter relay agent.
%%
%% Usage to connect to a server listening on the default port over TCP
%% and to listen on the default port over SCTP is as follows, assuming
%% diameter is already started (eg. diameter:start()).
%%
%% Eg. relay:start().
%% relay:connect(tcp).
%% relay:listen(sctp).
%%
