* --- THIS FILE GENERATED BY S-FUNCTION BUILDER: 2.0 ---
*
* This file is an S-function produced by the S-Function
* Builder which only recognizes certain fields. Changes made
* outside these fields will be lost the next time the block is
* used to load, edit, and resave this file. This file will be overwritten
* by the S-function Builder block. If you want to edit this file by hand,
* you must change it only in the area defined as:
*
* %%%-SFUNWIZ_defines_Changes_BEGIN
* #define NAME 'replacement text'
* %%% SFUNWIZ_defines_Changes_END
*
* DO NOT change NAME--Change the 'replacement text' only.
*
* For better compatibility with the Real-Time Workshop, the
* "wrapper" S-function technique is used. This is discussed
* in the Real-Time Workshop User's Manual in the Chapter titled,
* "Wrapper S-functions".
