   1 HXCOMM Use DEFHEADING() to define headings in both help text and texi
   2 HXCOMM Text between STEXI and ETEXI are copied to texi version and
   3 HXCOMM discarded from C version
   4 HXCOMM DEF(command, args, callback, arg_string, help) is used to construct
   5 HXCOMM monitor commands
   6 HXCOMM HXCOMM can be used for comments, discarded from both texi and C
