Configuration properties that can be defined via the CLI, system properties, environment variables, or file.

This project provides configuration properties, such that ANYTHING in the config file can ALSO be passed in on the command line or as an env/system property

commandline > system property > environment variable > properties file

Once a property has been defined, it cannot be overloaded again via a different method, as specified in the above hierarchy,

During a save operation, overloaded values will be ignored unless they were manually changed to something different

Additionally, it is possible to set an environment variable names that might conflict with the standard set of names, for example,

PATH

• The system uses PATH, but if we want to use path for something different, we can via setting the prefix.
• For example, setting the prefix to CONFIG__ means that for us to set the path property, we set it via

CONFIG__path="/home/blah/whatever"

• And this way, OUR path does not conflict with the system path.
