[Zope] Giving out STDOUT

Hi all, I wrote an external method which compiles a TeX-Source with latex2html. It's very simple... it only calls the command with os.system('latex2html /path/to/uploaded_files/%s' %file.filename) This command causes an output like "This is latex2html version..." and so on. Now I want to give out this Output in a Textarea on a zope site. Is this possible in a way? I tried to do that with the return value but it didn't work... any ideas? System: SuSE linux, zope 2.6.1 Thanks a lot mas
