What is the priority of loading values?

[sharonjl]

In which order does the lib load values? Does the config file override command line flag?

I believe it depends on what loader you use.
For the default loader: https://github.com/koding/multiconfig/blob/master/multiconfig.go#L23-L24

If you don't like this default order, you can construct your own loader with whatever order you want.
