--The interface routines for reading and writing PLY polygon files.
--
--Greg Turk, February 1994
--
-----------------------------------------------------------------
--
--A PLY file contains a single polygonal _object_.
--
--An object is composed of lists of _elements_.  Typical elements are
--vertices, faces, edges and materials.
--
--Each type of element for a given object has one or more _properties_
--associated with the element type.  For instance, a vertex element may
--have as properties the floating-point values x,y,z and the three unsigned
--chars representing red, green and blue.

--Header for PLY polygon files.
--
--- Greg Turk, March 1994
--
--A PLY file contains a single polygonal _object_.
--
--An object is composed of lists of _elements_.  Typical elements are
--vertices, faces, edges and materials.
--
--Each type of element for a given object has one or more _properties_
--associated with the element type.  For instance, a vertex element may
--have as properties three floating-point values x,y,z and three unsigned
--chars for red, green and blue.
