Steve-

	Ruby has great support for YAML its basically all parsed for you.  
Here's a little irb session to show you. The "y" command is just like  
the  'p' command you use to inspect an object. The 'y' just pretty  
prints to yaml format:

ezras-powerbook-g4-17:~/Desktop/rimport root# irb
 >> require 'yaml'
=> true
 >> hash = {:name => 'Steve Litt', :list => 'rubytalk', :topic =>  
'UMENU'}
=> {:list=>"rubytalk", :topic=>"UMENU", :name=>"Steve Litt"}
 >> y hash
---
:list: rubytalk
:topic: UMENU
:name: Steve Litt
=> nil
 >> array = %w{ one two three four five six }
=> ["one", "two", "three", "four", "five", "six"]
 >> y array
---
- one
- two
- three
- four
- five
- six
=> nil
 >> x = YAML::dump_stream array
=> "--- \n- one\n- two\n- three\n- four\n- five\n- six"

	There is plenty more goodness in there like yaml dumping your custom  
ruby objects. There are a few limitations though, mainly you cannot  
dump any code with procs or lambdas in them because they can't be  
serialized to yaml.
