libsolv-tools 0.7.22-1build2 (amd64 binary) in ubuntu lunar

 This dependency solver code in this package is based on two major, but
 independent, blocks:
 .
 1. Using a dictionary approach to store and retrieve package
    and dependency information.
 2. Using satisfiability, a well known and researched topic, for
    resolving package dependencies.
 .
 This package contains command-line tools that facilitate using libsolv.
