appstream-util - 0.7.18-1+deb11u1pureos1 main

AppStream is a cross-distribution effort for creating and sharing
metadata about software components available in the package repositories
of a distribution.
.
This package provides an utility to work with AppStream metadata, which uses
libappstream-glib.
.
It also contains Autotools macros to easily integrate AppStream metadata into
an Autotools-based buildsystem, by running 'appstream-util' to validate the
files before installing them.
