[Zope] Access to file content

Hi, I want to be able to display some information from a file, that is also in a local filesystem. As you know, the messages that we send to eachothers are sent in mime type and when the are display in our screen, only is showed the Subject, >From who, the Date and the content of that message. Is something like this that I'm trying to do. Can anyone help me on this? Please send your answers to: psilva@ruido-visual.pt Thanks, Pedro
