node-config binary package in Ubuntu Oracular amd64

 Node-config organizes hierarchical configurations for application deployments.
 .
 It allows defining a set of default parameters, and extend them for different
 deployment environments (development, qa, staging, production, etc.).
 .
 Configurations are stored in configuration files within an application, and can
 be overridden and extended by environment variables, command line parameters,
 or external sources.
