**** '''Description:''' The SRFS chunk contains a list of the names of all the surfaces in an object (note that in LightWave 3D terminology, the word "surface" is defined as a set of attributes that describe the color and shading characteristics of a group of polygons). Each surface name appears as a null-terminated character string. If the length of the string (including the null) is odd, an extra null byte is added. Surface names should be read from the file until as many bytes as the chunk size specifies have been read.

**** '''Description:''' The CRVS chunk contains a list of all the spline curves in an object. Each entry consists of a short integer specifying the number of vertices in a curve followed by that many short integers specifying the vertices themselves in sequential order, followed by a short integer specifying which surface is used by the curve, followed by another short integer specifying bit-flags associated with the curve.  If bit zero is set then the first point is a continuity control point, and if bit one is set then the last point is.  The point and surface indices are as they are in the POLS chunk, except that curves cannot have details.  Curves should be read from the file until as many bytes as the chunk size specifies have been read.
