APT-RPM is a version of the Advanced Packaging Tool modified to work with the RPM Package Manager. It was originally ported to RPM by Alfredo Kojima and then further developed and improved by Gustavo Niemeyer, both working for the Conectiva Linux distribution at the time.
In March 2005 the maintainer of the program, Gustavo Niemeyer, announced that he would not continue developing it and that he would instead focus on Smart Package Manager, which was planned as a successor to APT-RPM.
In March 2006 development was picked up again by Panu Matilainen from Red Hat at a new home, introducing basic multilib functionality and support for common repository metadata.
