Demonstrates how to initiate an archive retrieval job to download an archive. Lua

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- --------------------------------------------------------------------------
-- Note: The above REST connection and setup of the AWS credentials
-- can be done once.  After connecting, any number of REST calls can be made.
-- The "auto reconnect" property passed to rest.Connect indicates that if
-- the connection is lost, a REST method call will automatically reconnect
-- if needed.
