RPC::Serialized::Handler::YATG::Store is an RPC handler for YATG::Store::Disk.
This module implements an RPC::Serialized handler for YATG::Store::Disk. There is no special configuration, and all received parameters are passed on to YATG::Store::Disk::store() verbatim.
You'll need to run an RPC::Serialized server, of course, and configure it to serve this handler. There are files in the examples/ folder of this distribution to help with that, e.g. rpc-serialized.server.yml:
# configuration for rpc-serialized server with YATG handlers
You should head over to the RPC::Serialized documentation to learn how to set that up. We use a pre-forking Net::Server based implementation to receive port traffic data and store to disk, then serve it back out to CGI on a web server.
