NAME

6       challenged - detect broken packages due to obsolete dependencies
7

SYNOPSIS

9       challenged [options] Packages file(s)
10

DESCRIPTION

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