This is the packaging of Dandified Yum (DNF), the next upcoming major version of Yum.
It does package management using RPM, libsolv and libdnf libraries.
It utilizes librepo for metadata handling and package downloads.
It uses libcomps to process composition group metadata.
DNF is being packaged for Solus to enable setting up containers/chroots of
RPM-based Linux distributions, specifically with tools like Mock for
building RPMs for RPM-based Linux distributions from within Solus.
This is required to update Mock to the latest version.
