Subject: [GULF] Find the test dir

Don't know how much gulf this can take, but I sure would like as small
a version as I can get.

  paths = File.expand_path(File.dirname(__FILE__)).split('/')
  paths.size.downto(1) do |i|
    f = (paths.slice(0..i)+['test']).join('/')
    $TESTDIR = File.join(f,'FIXTURE') if File.directory?(f)
  end
  raise unless $TESTDIR
