If you run a script with rubyw under Windows and the script writes to  
stdout, is there a way to capture that output without modifying the  
script? Is there a rubyw option for specifying where the output should  
go?

I just noticed that you want to do this without modifying the script.  
This would be a better way to do it then.

c:\rubyscripts\>rubyw test.rbw \> test.log  
c:\rubyscripts\>

sorry, hit send by accident.

Anyway, rubyscript2exe suggests doing this:

$stdout = $stderr = File.new(“/path/to/temp/application.log”, “w”)
