There is a lot of literature about it. You can download our first chapter for free at Manning's Spring Roo in Action page, which goes through what Roo is for. Also, take a look at the project home page, which references a lot of source literature, including the user guide, which is also pretty good at pointing out the basics, as well as a video or two, Roo in 15 minutes, and more.
It's basically a tool that allows you to create and update a project with features without hand-wiring them yourself. For example, it sets up JPA, Web MVC, etc...
