   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

 353
 354 @table @var
 355 @item count
 356 is the number of items to be dumped.
 357
 358 @item format
 359 can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
 360 c (char) or i (asm instruction).
 361
 362 @item size
 363 can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
 364 @code{h} or @code{w} can be specified with the @code{i} format to
 365 respectively select 16 or 32 bit code instruction size.

 958 @item acl_allow @var{aclname} @var{match} @code{allow|deny} [@var{index}]
 959 Add a match rule to the access control list, allowing or denying access.
 960 The match will normally be an exact username or x509 distinguished name,
 961 but can optionally include wildcard globs. eg @code{*@@EXAMPLE.COM} to
 962 allow all users in the @code{EXAMPLE.COM} kerberos realm. The match will
 963 normally be appended to the end of the ACL, but can be inserted
 964 earlier in the list if the optional @var{index} parameter is supplied.
