This is for a utility/tool called hibernate that we are incorporating =
into our application and it uses a configuration file called =
hibernate.cfg.xml that I do not think that I can split.

I'm currently using the expandproperties filterread along with loadfile =
to load the environment specific settings. I can't version the =
development copy because I haven't found an ANT way to clip the section =
of the original file that contains the development environment setting =
out before I load the other environment settings in.

I would split the properties (build.propeties, prod.propeties, =
test.properties, ...) and load two of them:

<property name=3D"system" value=3D"prod"/> (prod,test,dev...) <property =
file=3D"${system}.properties"/> <property file=3D"build.properties"/>

build.properties contains all properties and in the other files you =
could overwrite (that's why it's loaded first) specific values.
