Application settings

[FoxyBrown via Digitalmars-d-learn]

What's the "best" way to do this? I want something I can simply 
load at startup in a convenient and easy way then save when 
necessary(possibly be efficient at it, but probably doesn't 
matter).

Simply json an array and save and load it, or is there a better 
way?

Ideally, I'd like to store the settings as part of the binary to 
keep everything together but that poses a few issues I think.
