 * Description:
 *   Before editing this file, please contact us.
 *
 *	This file is read only at compile time
 *
 *    It holds the enumeration of the classes needed by the acedb kernel.
 *    The additional application classes are listed in wspec/classes.wrm
 *    but do not need a hard choice of their number
 *
 *    Each #define line correspond to a class
 *    These numbers must NOT be repeated nor modified
 *    They are explicitelly repeated in pickDefineSystemClasses.
 *    
 *    Class properties, formerly defined in this file, are
 *    now in wspec/options.wrm 
 *
 *    The total number of MainClasses cannot exceed 255
