where is the installation web path (horde)

[belahcene <belahcene@iap-cu.dz>]

Hi,
I ve just install horde3 and turba2 from the deb package ( included in 
the official sarge), the  files  (   php files too) are installed in 
/usr/share/.....,  the my web is in /var/www so how to run the php files 
and configure. No  specification is given the /etc/horde/config.
Is there a small doc for horde/turba on debian.
thanks a lot
best regards
bela
