=head1 SYNOPSIS

   aemp command args...

   # protocol commands
   aemp snd <port> <arg...>    # send a message
   aemp mon <port>             # wait till port is killed

   # node configuration: secret
   aemp gensecret              # generate a random shared secret
   aemp setsecret <secret>     # set the shared secret
   aemp clrsecret              # remove the secret

   # node configuration: TLS
   aemp setcert <file>         # set a certificate (key.pem + certificate.pem)
   aemp clrcert                # remove certificate
   aemp gencert                # generate a random certificate
