   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

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

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