tool to create RPM repository metadata (C implementation)

 The createrepo_c tool generates the repodata directory and XML metadata that
 makes up a repository of RPM packages. This repository format is supported
 by apt-rpm, red-carpet(zen), smartpm, up2date, yast, and yum.
 .
 This package is similar to the apt-ftparchive or reprepro commands, but for
 working with RPM repositories.
