[Zope3-checkins] CVS: Products3/MySQLdbDA - Adapter.py:1.1 __init__.py:1.1 configure.zcml:1.1

[Christian Theune]

Update of /cvs-repository/Products3/MySQLdbDA
In directory cvs.zope.org:/tmp/cvs-serv4450/MySQLdbDA

Added Files:
	Adapter.py __init__.py configure.zcml 
Log Message:
initial checkin for the "database adapter collection"

those are initial drafts. The mysql adapter is tested and able to connect and query
as well as the sapdb. Postgres has already been there.

There will be a lot of issues with converting custom data types into
the zopish ones (see BLOB/CLOB...).

The other database adapters aren't tested anyway, but probably work,
as it has mostly been an "edit and replace" work. 

(Is that a sign of refactoring?)
