[Zope] File I/O in Zope

[Tino Wildenhain]

Hi Chris,

first: please use only plain text for mailinglist. Most people
dont like html text there.

Zopes DTML and Python Script Objetcs are in a security sandbox
for good reason. (see the documentation for the reasons, they are
explained in great detail)
However, if you _really_ nead to access a file in the filesystem,
you have to use an external method. For security reasons dont
use the filename as a parameter for this function or only
after excessive testing of the name.
