[EP-tech] restrict file-upload

[irene.eglin at unibas.ch (Irene Eglin)]

Hi everyone

Is there a possibility to disallow the upload of other files than pdf?
(I'm looking for something like "required_formats", but 
"allowed_formats" instead)

And can anybody tell me - or has an idea - how to allow only one file 
per eprint-object?

Any hints would be apreciated!

Thans a lot,
Irene
