If you have a multisite installation and you have different ezinstallation on the same machine e.g.

live => svn live branch
trunk => svn trunk

and you don't want to change the DatabaseSettings in the site.ini of the siteaccesses ( for better mergeing between trunk and live branch ) this patch is usefull.

It allows you to define a database postfix which is append to the Database name. For example we want to set up a trunk development.

# example for a trunk system  ezroot/ override/ site.ini.append.php
# 
[DatabaseSettings]
Database=ez40_mysite

# if defined Databasename is extended by DatabasePostfix
# e.g. ez40_mysite   will be  ez40_mysite-trunk
DatabasePostfix=-trunk

It's very handy
If you did not understand this patch - feel free to ask.

Hopefully this will be included to the ez core.

Thank's
