[Zope] Customising APE to a new database

Hi, I am aware that APE (which uses ZOPE) has support for MySQL and Postgresql. Can someone guide me on customising it to add a new database. I am interested in the codes in APE that need to be changed so that a new database can be added on to APE's horizon. Thanks in advance. _________________________________________________________________ Maximum benefits! http://go.msnserver.com/IN/51406.asp No minimum balance!
