-- The contents of the token should be executed and the results returned.
--

	function suite.executesTokenContents()

-- If the value contains more than one token, then should all be expanded.

-- If the token replacement values contain tokens themselves, those
-- should also get expanded.

-- If a path field contains a token, and if that token expands to an
-- absolute path itself, that should be returned as the new value.

-- If a non-path field contains a token that expands to a path, that
-- path should be converted to a relative value.
