Overview

Helper class to load YAML configuration files. Any ERB markup in the YAML file will be evaluated. The YAML file should be structured like this:

shared:
  foo: bar
  bar: baz

development:
  bar: qux
  biz: buz

test:
  bar: qix
  biz: biz

The section with the key matching the environment name is merged into the shared section. In this example, the development environment would have the following configuration:

{
  "foo" => "bar",
  "bar" => "qux",
  "biz" => "buz"
}

In addition, the keys are flattened into a one level deep hash with dots separating the keys.
