Feature Request: add support for config files

[konobi]

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.
