Need a gem or code to retrieve file Summary information with Ruby /Windows

[John]

Need a gem or code for Windows to retrieve file Summary information
with Ruby.

In writing a indexing program, I need the following fields from the
file properties
"summary information": such as Title, Subject, Author, Comments.

Thanks for the assistance,
John

# Ruby code to read Windows file summary information

require 'win32ole'

obj= WIN32OLE.new("Shell.Application")
folder=obj.nameSpace("d:\\0-dwn")
item = folder.items.item("test.doc")
(0..99).each do |i|
puts "#{i}-->"+folder.getDetailsOf(nil, {:iColumn => i }) +"--

"+folder.getDetailsOf(item, {:iColumn => i })

end
