 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.
