where did this faces-config.pageflow.xml file come from?

I am migrating an application to jsf 1.2 and now out of the blue there is a new .metadata folder in the project root with a WebConent folder inside there with a WEB-INF folder still deeper and inside there we now have a super important looking faces-config.pageflow file.

I open it up and see it has references to all of my开发者_如何学运维 included files from other jsps.

What is the point of this file? Does it really need to be there? Is there a way to turn that crap off?

It's part of JBoss JSF Tools plugin for Eclipse (and probably also other Eclipse-based JSF plugins I am not aware of). No, you can't turn it off, just configure your IDE to hide it if it is bothering you somehow.
