   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

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

 942 certificate distinguished name, and SASL username respectively.

 970 Add a match rule to the access control list, allowing or denying access.
 971 The match will normally be an exact username or x509 distinguished name,
 972 but can optionally include wildcard globs. eg @code{*@@EXAMPLE.COM} to
 973 allow all users in the @code{EXAMPLE.COM} kerberos realm. The match will
 974 normally be appended to the end of the ACL, but can be inserted
 975 earlier in the list if the optional @var{index} parameter is supplied.
