Papi is a tool to automate the building of NOSRC rpms. A nosrc.rpm is just like a regular source rpm (src.rpm), except it does not contain the source tarball for legal reasons.
Those nosrc.rpms are used for example with java packages, or with acroread. It is common when the closed-source sofware is freely downloadable. The point of making a nosrc.rpm is to integrate the application in the distribution properly.
But rebuilding a nosrc.rpm requires a knowledge of rpm building, and this is where Papi comes in. Papi presents the user with a list of supported packages, points the user to the program's download page, lets the user download it, asks the user for the downloaded file and rebuilds the rpm automatically. Then the user can just install the resulting rpm like any other rpm.
Papi is available with dialog-based (text-based) and zenity-based (graphical) interfaces, and writing another interface is easy since it is very modular.
