Create a context:

 package AnyEvent::FTP::Server::Context::EchoContext;
  
 use Moo;
  
 extends 'AnyEvent::FTP::Server::Context';
 with 'AnyEvent::FTP::Server::Role::Help';
  
 # implement the non-existent echo command
 sub help_echo { 'ECHO <SP> text' }
  
 sub cmd_echo
 {
   my($self, $con, $req) = @_;
   $con->send_response(211 => $req->args);
