Execute PRISM into HOSTAPD?

Hello, I am working with ubuntu 9.10, I installed freeradius server 2.1.10, Radius server is ok, but I am trying to implement "hostapd" in order to have a management of several access points. Thus, I installed the "hostapd" program, but I have a question concerning with other software related to hostapd. I downloaded PRISM by using the "update manager" utility provided by Ubuntu. How can I execute PRISM by using a terminal? Which are the commands to execute PRISM? Do you have a "quick install" document to install PRISM? Thanks in advance. Octavio Ramírez Rojas
