Config-API

This is an excellent application.

• It allows to create a base configuration and handle variants.
• And it's an excellent readable and easy-to-understand documentation.
• On top, it is JSON based and therefore well suited to source and version management

The original CachéParameterFile iris.cpf does a mimic of versioning.
But it is buried deep into the installation directory and as cryptic as the
Egyptian Book of the Dead. [reserved to the priest of IRIS cultus] wink

I was waiting for something similar useful for decades!
