"The pungi project is two things. First and foremost it is a free opensource tool to spin Fedora installation trees / isos. It will be used to produce Fedora releases from Fedora 7 on until it is replaced by something better. Secondly pungi is a set of python libraries to build various compose like tools on top of. Pungi provides a library with various funtions to find, depsolve, and gather packages into a given location. It provides a second library with various functions to run various Anaconda tools on the gathered packages and create isos from the results."
