This wants to be a magic configuration loader who looks for configuration automatically in many places, like:
- ./.CONFNAME.yml
- ~/.CONFNAME.yml
- .CONFNAME/conf.yml
Loads a YAML file looked upon in common places and returns a hash with appropriate values, or an exception
and maybe a nice explaination..
so you can call load_auto_conf('foo') and it will look throughout any ./.foo.yml, ~/.foo.yml or even /etc/foo.yml !
