I"m reading in a YAML file using the yaml library in Ruby.  My YAML
looks something like this:

config:
     value1: Something here
     value2: Something else

As I loop from the YAML like:

config["config"].each { |key, value| }

How could I set the key as an instance variable with the value of the
value of the key... resulting in:

@value1 = "Something here"
@value2 = "Something else"

Any thoughts?

config["config"].each {|key,value| instance_variable_set("@#{key}",
value)};

you'll probably want to remove spaces and convert odd chars in the key
to make sure it follows instance variable naming guidelines.
