+    (description
+     "ELPI implements a variant of λProlog enriched with Constraint
+Handling Rules, a programming language well suited to manipulate
+syntax trees with binders.
+
+ELPI is designed to be embedded into larger applications written in
+OCaml as an extension language.  It comes with an API to drive the
+interpreter and with an FFI for defining built-in predicates and data
+types, as well as quotations and similar goodies that are handy to
+adapt the language to the host application.
+
+This package provides both a command line interpreter (elpi) and a
+library to be linked in other applications (eg by passing -package
+elpi to ocamlfind).
+
+The ELPI programming language has the following features:
+
+@itemize
+@item Native support for variable binding and substitution, via an Higher
+Order Abstract Syntax (HOAS) embedding of the object language.  The
+programmer does not need to care about technical devices to handle
+bound variables, like De Bruijn indices.
+
+@item Native support for hypothetical context.  When moving under a binder
+one can attach to the bound variable extra information that is
+collected when the variable gets out of scope.  For example when
+writing a type-checker the programmer needs not to care about managing
+the typing context.
+
+@item Native support for higher order unification variables, again via
+HOAS.  Unification variables of the meta-language (λProlog) can be
+reused to represent the unification variables of the object language.
+The programmer does not need to care about the unification-variable
+assignment map and cannot assign to a unification variable a term
+containing variables out of scope, or build a circular assignment.
+
+@item Native support for syntactic constraints and their meta-level
+handling rules.  The generative semantics of Prolog can be disabled by
+turning a goal into a syntactic constraint (suspended goal).  A
+syntactic constraint is resumed as soon as relevant variables gets
+assigned.  Syntactic constraints can be manipulated by constraint
+handling rules (CHR).
+
+@item Native support for backtracking.  To ease implementation of search.
+
+@item The constraint store is extensible.  The host application can declare
+non-syntactic constraints and use custom constraint solvers to check
+their consistency.
+
+@item Clauses are graftable.  The user is free to extend an existing
+program by inserting/removing clauses, both at runtime (using
+implication) and at \"compilation\" time by accumulating files.
