outdated [option] ... file ...


outdated identifies in a debian package repository those packages that are not installable with respect to that repository by the their inter-package relationships (dependencies, conflicts, ...), and that furthermore cannot become installable (in the current version) how matter how the rest of the repository evolves. This means that this package has to be updated in the repository to ever become installable again.

Input specification

Input files have to contain stanzas in the format of deb-control(5), separated by one blank line. For instance, the Packages files as found on a Debian mirror server, or in the directory /var/lib/apt/lists/ of a Debian system, are suitable as input. The repository used in the analysis consists of the union of all packages from the input files.

Output specification

The output of outdated is in the YAML format.
