NAME

       dose-challenged - detect broken packages due to obsolete dependencies

SYNOPSIS

       dose-challenged [options] Packages file(s)

DESCRIPTION

       dose-challenged performs a speculative analysis of the repository to identify those packages that, if upgraded to a specific version, would
       break a large number of other packages in the repository. This tool would be particularly useful during the upgrade of a specific component
       to evaluate its impact on the software archive.

       -c      Print the list of packages in a cluster

       --checkonly
	       Select a subset of packages to check. By default all packages are checked.

       -v      Enable info / warnings / debug messages. This option may be repeated up to three times in order to increase verbosity.
