Utility to work with AppStream metadata

 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.
