Kill Files
==========

   Gnus still supports those pesky old kill files.  In fact, the kill
file entries can now be expiring, which is something I wrote before
Daniel Quinlan thought of doing score files, so I've left the code in
there.

   In short, kill processing is a lot slower (and I do mean _a lot_)
than score processing, so it might be a good idea to rewrite your kill
files into score files.

   Anyway, a kill file is a normal `emacs-lisp' file.  You can put any
forms into this file, which means that you can use kill files as some
sort of primitive hook function to be run on group entry, even though
that isn't a very good idea.

   Normal kill files look like this:

     (gnus-kill "From" "Lars Ingebrigtsen")
     (gnus-kill "Subject" "ding")
     (gnus-expunge "X")

   This will mark every article written by me as read, and remove the
marked articles from the summary buffer.  Very useful, you'll agree.

   Other programs use a totally different kill file syntax.  If Gnus
encounters what looks like a `rn' kill file, it will take a stab at
interpreting it.

   Two summary functions for editing a GNUS kill file:

`M-k'
     Edit this group's kill file (`gnus-summary-edit-local-kill').

`M-K'
     Edit the general kill file (`gnus-summary-edit-global-kill').

   Two group mode functions for editing the kill files:

`M-k'
     Edit this group's kill file (`gnus-group-edit-local-kill').

`M-K'
     Edit the general kill file (`gnus-group-edit-global-kill').

   Kill file variables:

`gnus-kill-file-name'
     A kill file for the group `soc.motss' is normally called
     `soc.motss.KILL'.  The suffix appended to the group name to get
     this file name is detailed by the `gnus-kill-file-name' variable.
     The "global" kill file (not in the score file sense of "global", of
     course) is just called `KILL'.

`gnus-kill-save-kill-file'
     If this variable is non-`nil', Gnus will save the kill file after
     processing, which is necessary if you use expiring kills.

`gnus-apply-kill-hook'
     A hook called to apply kill files to a group.  It is
     `(gnus-apply-kill-file)' by default.  If you want to ignore the
     kill file if you have a score file for the same group, you can set
     this hook to `(gnus-apply-kill-file-unless-scored)'.  If you don't
     want kill files to be processed, you should set this variable to
     `nil'.

`gnus-kill-file-mode-hook'
     A hook called in kill-file mode buffers.
