<P>
All modules belonging to the APRON interface itself (<CODE>Scalar</CODE>,
<CODE>Interval</CODE>, ..., <CODE>Manager</CODE>, <CODE>Linexpr0</CODE>,
... <CODE>Abstract1</CODE>) are included in a big encapsulating module named
<CODE>Apron</CODE>. In addition, there are modules like <CODE>Box</CODE>
(intervals), <CODE>Oct</CODE> (octagons), <CODE>Polka</CODE> (linear equalities
and convex polyhedra) and <CODE>Ppl</CODE> (convex polyhedra and linear
congruences) not included in <CODE>Apron</CODE>.
</P><P>
Generic abstract values have the type <CODE>'a Abstract1.t</CODE>, generic
managers the type <CODE>'a Manager.t</CODE>. A typical operation like the
emptiness test has the type <CODE>val is_bottom : 'a Manager.t -> 'a
Abstract1.t -> bool</CODE>.
</P><P>
Octagons of OCTAGON have the type <CODE>Oct.t
Apron.Abstract1.t</CODE>. The corresponding managers have thus the type
<CODE>Oct.t Manager.t</CODE>.
</P><P>
See <A HREF="../mlapronidl/index.html">OCaml interface</A> for the
documentation.
