+%description
+Dose3 is a framework made of several OCaml libraries for managing
+distribution packages and their dependencies.
+
+Though not tied to any particular distribution, dose3 constitutes a pool of
+libraries which enable analyzing packages coming from various distributions.
+
+Besides basic functionalities for querying and setting package properties,
+dose3 also implements algorithms for solving more complex problems
+(monitoring package evolutions, correct and complete dependency resolution,
+repository-wide uninstallability checks).

+# Since these are applications, I think the correct name is "dose3-tools"
