Reading a libconfig config

[Unknown User]

I am using Conf::Libconfig to read a libconfig config file.
  - are there any better modules to read it?
  - If not, is it possible with Conf::Libconfig to print out all the
entries in the config file in a JSON/YAML format? I dont see any option
that will allow me to refer to more than one key at a time.

Thanks,
Super
