-@cindex nnkiboze
-@cindex kibozing
-
-@dfn{Kibozing} is defined by the @acronym{OED} as ``grepping through
-(parts of) the news feed''. @code{nnkiboze} is a back end that will
-do this for you. Oh joy! Now you can grind any @acronym{NNTP} server
-down to a halt with useless requests! Oh happiness!
-
-@kindex G k (Group)
-To create a kibozed group, use the @kbd{G k} command in the group
-buffer.
-
-The address field of the @code{nnkiboze} method is, as with
-@code{nnvirtual}, a regexp to match groups to be ``included'' in the
-@code{nnkiboze} group. That's where most similarities between
-@code{nnkiboze} and @code{nnvirtual} end.
-
-In addition to this regexp detailing component groups, an
-@code{nnkiboze} group must have a score file to say what articles are
-to be included in the group (@pxref{Scoring}).
-
-@kindex M-x nnkiboze-generate-groups
-@findex nnkiboze-generate-groups
-You must run @kbd{M-x nnkiboze-generate-groups} after creating the
-@code{nnkiboze} groups you want to have. This command will take time.
-Lots of time. Oodles and oodles of time. Gnus has to fetch the
-headers from all the articles in all the component groups and run them
-through the scoring process to determine if there are any articles in
-the groups that are to be part of the @code{nnkiboze} groups.
-
-Please limit the number of component groups by using restrictive
-regexps. Otherwise your sysadmin may become annoyed with you, and the
-@acronym{NNTP} site may throw you off and never let you back in again.
-Stranger things have happened.
-
-@code{nnkiboze} component groups do not have to be alive---they can be dead,
-and they can be foreign. No restrictions.
-
-@vindex nnkiboze-directory
-The generation of an @code{nnkiboze} group means writing two files in
-@code{nnkiboze-directory}, which is @file{~/News/kiboze/} by default.
-One contains the @acronym{NOV} header lines for all the articles in
-the group, and the other is an additional @file{.newsrc} file to store
-information on what groups have been searched through to find
-component articles.
-
-Articles marked as read in the @code{nnkiboze} group will have
-their @acronym{NOV} lines removed from the @acronym{NOV} file.

You can set the process mark on both groups and articles and perform
