+%description
+This package contains a lightweight deductive database system.
+Queries and database updates are expressed using Datalog--a
+declarative logic language in which each formula is a function-free
+Horn clause, and every variable in the head of a clause must appear in
+the body of the clause.  The use of Datalog syntax and an
+implementation based on tabling intermediate results, ensures that all
+queries terminate.
+
+The components in this package are designed to be small, and usable on
+memory constrained devices.  The package includes an interactive
+interpreter for Datalog, and the development package has a library
+that can be used to embed the interpreter into C programs.
