What is Primavera Project Planner (P3) all about?

[t_amos]

I have to interview with a company which one of the requirements is having experience in Primavera. The only experience that I lack in an otherwise impressive resume.
I would like someone to give me some tips on what th program is all about so that I don't appear clueless if a question pertaining to the topic is raised.
Thanks guys.
