-description         A modern C++ library providing numerical abstractions
+description         Parma Polyhedra Library
+long_description    The Parma Polyhedra Library (PPL) provides numerical \
+                    abstractions especially targeted at applications in \
+                    the field of analysis and verification of complex \
+                    systems. These abstractions include convex polyhedra, \
+                    some special classes of polyhedra shapes that offer \
+                    interesting complexity/precision tradeoffs, and grids \
+                    which represent regularly spaced points that satisfy \
+                    a set of linear congruence relations. The library \
+                    also supports finite powersets and products of \
+                    polyhedra and grids, a mixed integer linear \
+                    programming problem solver using an exact-arithmetic \
+                    version of the simplex algorithm, a parametric integer \
+                    programming solver, and primitives for termination \
+                    analysis via the automatic synthesis of linear ranking \
+                    functions.
 
-long_description    The Parma Polyhedra Library (PPL) is a modern C++ library \
-                    providing numerical abstractions especially targeted at \
-                    applications in the field of analysis and verification of \
-                    complex systems. The PPL can handle all the convex \
-                    polyhedra that can be defined as the intersection of a \
-                    finite number of (open or closed) hyperspaces, each \
-                    described by an equality or inequality (strict or \
-                    non-strict) with rational coefficients. The PPL also \
-                    handles restricted classes of polyhedra that offer \
-                    interesting complexity/precision tradeoffs. The library \
-                    also supports finite powersets of (any kind of) polyhedra \
-                    and linear programming problems solved with an \
-                    exact-arithmetic version of the simplex algorithm.
