node-dashdash Feature Request: add support for config files

It'd be nice if there was support for config files like there is for environment variables. That'd make cmdln the only library I'd need to bootstrap a command line app.

Can you elaborate? How would that look in dashdash? What configure file syntax would it specify? I'm slightly skeptical

Have a config object that's pre-loaded with a "get" method. Then each place you'd specify an ENV var, you define a string to use with get(). Then the format of the file is of no consequence.

So you'd pass a "config" object into the dashdash constructor, then for each option call get() on the config object with the appropriate string and have the returned value used for defaults.
