Installing edge

I need some features from edge, and have never installed it before. I'm
using RoR on a hosted system, they do not have svn.

It seems like I should take the files from

and put them into vendor/rails, and then follow the remaining
installation tips.

Since we don't have subversion installed, is there an ftp site where I
can get the files from?

Taking from branches/1.2-pre-release would be good too I think. It’ll give you a clearer picture of the next release.
