The thing to watch out for under Windows is that (at least on some 
versions)

   script.rb > results.txt

doesn't work and you have to write

   ruby script.rb > results.txt

This is caused by the fact that the cmd.exe has to use a different WIN32 
API call to execute the script using the file extension mapping than 
what it would use for .exe and thatthe former doesn't preserve the 
STDxxx redirection.
