What does the red arrow pointing up and to the right mean in the package explorer in Eclipse?

Question

I am using the SpringSource Tool Suite (essentially Eclipse Helios ++) and I just started using Subversive. I used all the tools except Subversive for quite some time, and I have never seen these red arrow icons before (or are they called “decorations”?), So I suspect that Subversive is the source, but I can not find anything in the line that says what they mean.

Answer 1

These are those that are subversive decorations (arrow is for “switching”)
