 *\n\
 *   A list of all the enum classes used in an ISA.\n\
 *   It exports the following:\n\
 *",
" *   typedef (enum) ISA_ENUM_CLASS\n\
 *       An enumeration of the enum classes.\n\
 *\n\
 *   typedef (enum) ISA_ENUM_CLASS_VALUE\n\
 *       An enumeration of the enum class values.\n\
 *\n\
 *   typedef (struct) ISA_ENUM_CLASS_INFO\n\
 *       Contains info about first and last ECV in the EC.\n\
 *       The contents are private.\n\
 *",
" *   typedef (struct) ISA_ENUM_CLASS_VALUE_INFO\n\
 *       Contains info about name and int-value of the ECV.\n\
 *       The contents are private.\n\
 *\n\
 *   const char * ISA_EC_Name (ISA_ENUM_CLASS)\n\
 *       Returns name of EC.\n\
 *\n\
 *   ISA_ENUM_CLASS_VALUE ISA_EC_First_Value (ISA_ENUM_CLASS)\n\
 *       Returns the first ECV for the specified EC.\n\
 *" ,
" *   ISA_ENUM_CLASS_VALUE ISA_EC_Last_Value (ISA_ENUM_CLASS)\n\
 *       Returns the last ECV for the specified EC.\n\
 *       Note that it assumes all ECV for an EC are in the\n\
 *       first/last range given by the above two functions.\n\
 *\n\
 *   const char * ISA_ECV_Name (ISA_ENUM_CLASS_VALUE)\n\
 *       Returns name of ECV.\n\
 *" ,
" *   INT ISA_ECV_Intval (ISA_ENUM_CLASS_VALUE)\n\
 *       Returns int-value of ECV.\n\
