+PACKAGE := dss
+SLOGAN := the dyadic snapshot scheduler
+define DESCRIPTION1 :=
+	$(PACKAGE) maintains hardlink-based snapshots of a given directory on a
+	remote or local host using rsync's link-dest feature. The snapshots
+	are organized so that any snapshot can directly be deployed as an
+	(emergency) replacement for the primary system.
+endef
+define DESCRIPTION2 :=
+	$(PACKAGE) is admin friendly: It is easy to configure and needs little
+	attention after the initial setup. In particular, no full, incremental
+	or differential backups need to be configured, and there is no database
+	to maintain. $(PACKAGE) is also user-friendly: Assuming the snapshot server
+	allows read-only user access over the network, users can restore
+	accidentically removed files without admin intervention, using their
+	favorite file browser to copy files from the snapshot directory back
+	to the primary system.
+endef
+define DESCRIPTION3 :=
+	$(PACKAGE) keeps track of the age and the state of existing snapshots and
+	triggers snapshot creation and removal according to the configuration
+	settings. It tries to maintain a scheme where many recent snapshots
+	and few old snapshots exist, for example 16 snapshots newer than a
+	week, 8 snapshots between one and two weeks old, 4 snapshots between
+	two and three weeks old, and so on.
