can I batch select buffers in buffer menu mode?

can I batch select buffers in buffer menu mode?

[usman]

I often have many buffers open at the same time; when
I want to clean stuff up I hit 'C-x b', manually mark
ones I don't want around anymore, then hit 'x' to
delete them.

Is there a way I can specify a pattern and mark all
matching buffers for deletion? For instance, it'd be
great if I could say "M-x mark-matching ~/src/2.2/*.cpp"
to mark all buffers visiting files in that dir for
removal.

Thanks for any pointers, examples, etc.

For files (in Dired):
  dired-mark-files-regexp, which is bound to `% m' and to `% *'

For buffers (in *Buffer List*):
  I don't think there is a command to mark buffers via regexp, but you could
write one!

Does not ibuffer has support for this? The help text says:

    % n - mark buffers by their name, using a regexp

Is ibuffer a package apart from the buffer abilities that are a part of 
EMACS?

Thank you.

The original question was about marking buffers in *Buffer List* for
deletion. I'd say that should be pretty easy to code, by looking at 1) the
code in buff-menu.el and 2) the code for the similar Dired function,
`dired-mark-files-regexp' (in dired.el). Do something similar to
`dired-mark-files-regexp', and integrate it within `Buffer-menu-mode'. HTH,
Drew

there is also:

  (global-set-key "\C-xC-b" 'electric-buffer-list)

w/ which "d" marks for deletion, etc.  available since emacs 18...
