Ah, so it wasn't just me! ;-)

Can I make a guess? It's because Ant will not let you override
properties, right? If you say -Dproject.name=projectName on the command
line only very harsh measures will make the project.name go away. :-(
Measures of the sort of having custom tasks that have runProject methods
that use deprecated project.setUserProperty( "project.name",
newProjectName ) ? ;-)

No, not measurable at least. I thought I would make the multiple
invocation of the Centipede task go away. But I guess I thought wrong,
I'm still seeing that darn Centipede invocation bumper scroll past every
time.
