Deleting matched lines by marking lines in *occur* buffer

[Sivaram Neelakantan <nsivaram.net@gmail.com>]

Hi,

When I run M-x occur and get the following output

--8<---------------cut here---------------start------------->8---
5 matches for "\.txt" in buffer: indices.conf
     14:cnx_midcap_baseline.txt
     16:cnx_nifty_jr_baseline.txt
     18:sp_cnx_500_baseline.txt
     20:sp_cnx_defty_baseline.txt
     22:sp_cnx_nifty_baseline.txt
--8<---------------cut here---------------end--------------->8---

is there a way to mark the lines in this buffer and expunge the lines
in the corresponding source buffer?  A dired like support would be
useful.  I did check the emacswiki and none of the other suggested
packages seem to have support for this sort of thing.

Any suggestions?  I suppose there's delete-matching-lines but wouldn't
it also be useful in the occur buffer?
