Summary

Save lots of rebuilds by only depending on libraries a package really uses, and automatically detect and report invalid dependencies.

Rationale

Every time a library SONAME changes, all binaries and libraries depending on it have to be rebuilt. In some cases this can cause lots of unneeded rebuilds, because some binaries or libraries have NEEDED entries for stuff they don't use directly. For example, if a binary depends on library A, and library A depends on library B, it is not necessary that the binary also depends on library B.

Use Cases

Scope

This specification finds a way to utilise checklib to remove redundancies and fix dependencies of binary packages in Ubuntu.

Design

There is already a Debian tool (http://rerun.lefant.net/checklib/) that did this at some point for Debian, but the person responsible for it has stopped working on it. Running this tool for Ubuntu and fixing the problems would make transitions easier, and would also fix some missing dependencies.
