#load_auto_conf(confname, opts = {}) ⇒ Object

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 !
