+      A Package for Analyzing Lattice Polytopes (PALP) is a set of C
+      programs for calculations with lattice polytopes and applications to
+      toric geometry.
+
+      It contains routines for vertex and facet enumeration, computation of
+      incidences and symmetries, as well as completion of the set of lattice
+      points in the convex hull of a given set of points. In addition, there
+      are procedures specialised to reflexive polytopes such as the
+      enumeration of reflexive subpolytopes, and applications to toric
+      geometry and string theory, like the computation of Hodge data and
+      fibration structures for toric Calabi-Yau varieties.  The package is
+      well tested and optimised in speed as it was used for time consuming
+      tasks such as the classification of reflexive polyhedra in 4
+      dimensions and the creation and manipulation of very large lists of
+      5-dimensional polyhedra.
+
+      While originally intended for low-dimensional applications, the
+      algorithms work in any dimension and our key routine for vertex and
+      facet enumeration compares well with existing packages.
