[Zope] installing zope on ISPs server - in root dir, they say...

Hello again - One of the support people at my ISP instructed me to install the linux version of Zope in my root directory on their server. While The Zope Book advises to install in the Zope directory. My guess is that the ISP is new to Zope. Any suggestions?? I FTPd Zope-2.5.1-linux2-x86.gz to my root directory on my ISPs server. I untarred it and now there is a Zope-2.5.1-linux2-x86 directory with all the appropriate files and sub-directories in my root directory. Thanks- David dw@pzaz.net
