+%description
+CUDF (for Common Upgradeability Description Format) is a format for
+describing upgrade scenarios in package-based Free and Open Source
+Software distribution.
+
+In every such scenario there exists a package universe (i.e. a set
+of packages) known to a package manager application, a package status
+(i.e. the currently installed packages), and a user request (i.e. a
+wish to change the set of installed packages) that need to be
+fulfilled.
+
+CUDF permits to describe an upgrade scenario in a way that is
+both distribution-independent and package-manager-independent.
+
+CUDF offers a rigorous semantics of dependency solving that
+enables to independently check the correctness of upgrade
+solutions proposed by package managers.
+
+CUDF adoption would enable to share dependency solver components
+across different package managers, both intra- and
+inter-distributions.
