Message::Passing::DSL - An easy way to make chains of Message::Passing components.

This module provides a simple to use helper system for writing scripts which implement a Message::Passing server, like the built in message-pass script.
Constructs a log chain (i.e. a series of log objects feeding into each other), warns about any unused parts of the chain, and returns the chain head (i.e. the input class).
Maintains a registry / factory for the log classes, which is used to allow the resolving of symbolic names in the output_to key to function.
See example in the SYNOPSIS, and details on the other functions below.
Constructs a named output within a chain.
log_chain { output foo => ( class => 'STDOUT' ); .... };
Constructs a named filter (which can act as both an output and an input) within a chain.
log_chain { ... filter bar => ( output_to => 'stdout', class => 'Null' ); ... };
The last thing in a chain - produces data which gets consumed.
log_chain { ... input zmq => ( output_to => 'bar', class => 'ZeroMQ', bind => '...' ); .... }
This enters the event loop and causes log events to be consumed and processed.
Can be passed a log_chain to run, although this is entirely optional (as all log chains which are still in scope will run when the event loop is entered).
This module exists due to the wonderful people at Suretec Systems Ltd. <http://www.suretecsystems.com/> who sponsored its development for its VoIP division called SureVoIP <http://www.surevoip.co.uk/> for use with the SureVoIP API - <http://www.surevoip.co.uk/support/wiki/api_documentation>
