Possibly add a helper executable to configya with this functionality

[dcneiner]

If implemented, the user could run something like configya server/config.json and get a list of which environment variables would be needed to override keys in the config.

Proof of concept / working example: https://gist.github.com/9bbb9a1c38078788c511

Example command-line usage of that Gist

node ./configparse.js server/config.json --prefix LK

Input: config.json

{
    "nested": {
        "setting": {
            "value": true
        },
        "other": [ "cool" ]
    }
}

Output:

LK_NESTED_SETTING_VALUE="true"
LK_NESTED_OTHER="[\"cool\"]"

Thoughts?

I'd also like to improve this to warn when keys contain characters that may not be overrideable via an environment variable
