The first definition of a property wins -- that is understood. Now, play
the following scenario (real life for me right now):
* In ${user.home}/build.properties, I've defined my "commons-foo.jar"
to point at the released version of the foo package, because that is
what I generally want to use in my builds.
* In building this particular component, I need to use hot-off-the-presses
CVS code because I use features added since the release, so I override
"commons-foo.jar" in my component-local version.
Using your ordering, my override does not take effect -- putting the "user
local" import third lets me do it.
