DESCRIPTION
     This node specifies a piecewise-linear curve that is used as a profile
     for either a trimming patch of a Nurbs surface or for the bevel of
     SoText3. The index field indexes into the current profile coordinates
     (specified in an SoProfileCoordinate2 or SoProfileCoordinate3 node). If
     the last value of the index field is
     SO_LINEAR_PROFILE_USE_REST_OF_VERTICES (-1), all remaining coordinates in
     the current coordinates will be used, starting with the coordinate after
     the previous index (all coordinates will be used if
     SO_LINEAR_PROFILE_USE_REST_OF_VERTICES is the only value in the index
     field). For example, if index contains the values [2,0,-1] and there are
     4 profile coordinates (0-3), it is as if the index field contains
     [2,0,1,2,3].

FUNCTIONS

     SoType              SoLProfGetClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction, SoRayPickAction, SoCallbackAction
          Adds a profile to the current state.
