I have pretty close question.
I don't get how to locate files inside ruby-project. In Rails I've used 
'RAILS_ROOT' and it was clear to me how does it work.
And what about usual ruby app?

1. NetBeans generated TestUnit gets this string:
$:.unshift File.join(File.dirname(__FILE__),'..','lib')
What for?

2. My project structure:
project:
\lib
\lib\main.rb
\lib\some_file.rb
\lib\parsers\yaml_parser.rb
\data
\data\yaml_parser_config.yml
\data\source.scv
\data\Format_1.0.yml

I keep config files in 'data' catalog.

Is it good way to ref these resources in this way:

#Some TestUnit
def test_read
    @conf = YAML.load_file( 'data/Format_1.0.yml' ) #Good or bad?
    assert_equal(Hash, @conf.class)
    assert_equal("Dates",@conf['Dates']['class'])
    assert_equal(["id", "descr", "rough_est", "accurate_est", "spent", 
"left", "resource_id", "begin", "end"],@conf['Tasks']['fields_ordered'])
end

or in some Parser class:
@parser_config = YAML.load_file('data/Format_1.0.yml' ) )

Or I have to use some 'magic' ruby variables?
