Package datalog

A Lightweight Deductive Database using Datalog

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.
