+Contains processes for phonon propagation and interaction in materials.
+
+G4LatticeManager:  Singleton (TLS) for logical and physical lattices
+	associated with materials and volumes.
+
+G4LatticeReader:  Driver to create logical lattices by reading in
+	configuration files and velocity map tables.  NOTE:  This class will
+	be moved to source/materials/ once Release 10.0 is deployed.
+
+The lattice data files should be stored under $G4LATTICEDATA (set to
+"./CrystalMaps" by default, to support the extended example).  The
+configuration and velocity map files for a given material should be stored
+in a subdirectory with that material's name (e.g., "Ge").
+
+Documentation for the lattice configuration files will be expanded in the
+future.
+
+G4VPhononProcess:  Virtual base class for all processes below, providing
+	some utility functions.
+
+G4PhononDownconversion:  Process to convert single longitudinal phonons
+	either into pairs of two transverse phonons, or to emit a transverse
+	phonon.
+
+G4PhononReflection:  Placeholder process to reflect phonons off of crystal
+	surfaces.  Currently phonons are absorbed, or converted to hits.
+
+G4PhononScattering:  Process to scatter phonons off the surrounding
+	lattice.  Currently handles "transportation" as well, but each
+	scatter destroys the phonon and creates a new one.
+
+G4PhononPolarization:  Enum with conversion functions to map the three
+	phonon particle definitions onto internal codes (L=0, TS=1, TF=2).
+
+G4PhononTrackMap:  Singleton (TLS) map file to connect tracks with
+	wavevectors.  for temporary use until wavevector is added to G4Track
+	as a data member, after Release 10.0.
