Dear Zopistas
 
How can I display the installation path of Zope in a ZPT page. Something like this should do the trick (but it doesn't):
 
...
<form action="." method="post">
    <input type="text" name="filename" value="" tal:attributes="value $ZOPEHOME/lib/python/Products"/>
    <input type="submit" name="importFile:method" value="import file"/>
</form>
...
 
Any ideas or hints?
 
Thanks and best wishes
Andre
 
PS Maybe a "Browse..." button would be nice in addition to this if somebody has an example (JavaScript?).
