  Look up the SRPMs from which these binary RPMs were generated.

  This list will be displayed deduplicated and sorted.

Options:
  --full-name / --no-full-name
  --system / --no-system        If --system is specified, use the 'fedora',
                                'updates', 'source' and 'updates-source'
                                repositories from the local system
                                configuration. Otherwise, use the static data
                                from the sampledata directory.

Usage: whatpkgs.py neededby [OPTIONS] [PKGNAMES]...

  Look up the dependencies for each specified package and display them in a
  human-parseable format.

Options:
  --hint TEXT                     Specify a package to be selected when more
                                  than one package could satisfy a
                                  dependency.
                                  This option may be specified multiple times.
                                  For example, it is recommended to use
                                  --hint=glibc-minimal-langpack
  --recommends / --no-recommends
  --merge / --no-merge
  --full-name / --no-full-name
  --pick-first / --no-pick-first  If multiple packages could satisfy a
                                  dependency and no --hint package will
                                  fulfill the requirement, automatically

                                  sorted. It is recommended to use
                                  --hint instead, where practical.
