Tired of the recent spate of addgroup and rmgroup messages

Tue Feb 5 07:38:40 AEST 1991

I am posting this after seeing three requests from C News admins for
this sort of thing in the past two days.  It is the B News checkgroups,
pseudo-configed for C News, and modified C News newgroup and rmgroup scripts.

The newgroup and rmgroup scripts both mail the entire control article
(so all of the headers can be examined, too) to the admin if it means
changing the group to reflect the request of the message.  Neither
says anything at all for groups which are being blocked or refiled.

The checkgroups script was simply modified to suit more what I wanted;
I hate the extra lines of commands since I don't use them, and so I
commented them all out.  You can change them back by changing TAB-# to
just TAB throughout the script; beware that the commands which are
there to use inews are _not_ the right way to do it with C News.

Personally, I've switched to Matthias Urlichs's perl checkgroups with
a bunch of hacks.  I'll be sending my changes to him soon and maybe
whatever merges out of that will be appearing here again.

Change the config path in all scripts, probably to /usr/lib/news/config
as long as you are running standard paths.  Also change the MAIL variable
as appropriate in {new,rm}group.  Put checkgroups in $NEWSBIN/maint and
cp /bin/true to $NEWSBIN/ctl/checkgroups :-) .

#! /bin/sh

# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
