For those who keep archives of stuff from net.sources using an
Alan Watt lbgm (little bird gave me) style archive then you might
want a convenient way to delete the junk that may get saved there.
I have written some small scripts which make that job easier.
When you come across junk simply pipe the offending article into
zap.so and it creates a script which will remove the article from
your lbgm archive. After your finished reading news just invoke tozap
which was created by zap.so.
I have include Alan Watt's original article. As always please
keep me informed of enhancements or bugs.

From rocheste!seismo!harpo!decvax!ittvax!swatt Fri Apr 8 17:01:12 1983
Subject: savesource script
Newsgroups: net.sources
I don't have space to save all news forever, but I decided some time
ago that net.sources was worth keeping around, hence "savesource".
Usage is from you news "sys" file:
SOURCES:net.sources:B:/usr/lib/news/savesource [ srcdir ]
where <srcdir> is where you want the stuff to go. In there will
appear the file "save.log", which contains the news header of
every news article saved, and files of the form:
${month}_${day}.${unique}
(as in "Apr_8.4552"), each file containing an article. The log
file will point to the saved article. There is a lockout against
concurrent runnings of savesource.
You have to periodically go in by hand and delete obvious junk
(discussions and requests for stuff), and also to weed out which
version you want to keep if something is posted several times.
I have everything posted on net.sources since August 15th of last
year.
