Console2SAAS – what I learned from third chapter

The third chapter of the mini-e-book Console2SAAS shows me that I should not re-invent the wheel. Of course,it is easy to make a code that reads settings – but why do it so if there are libraries already in the framework  ?

Also,even a such simple task ( reading the setting),in order to do properly,there is some amount of work and priorities involved – the application can read from environment variables,command line,configuration file,code … plenty of options – and what if the user mix and match those ? What you pick first ?
