When nnmaster is started the first time after initializing nn's
database, it will attempt to fetch all the articles from the nntp
server.  It does this by successively requesting each article in the
range min..last obtained from the NNTP server.  Often the 'min' number
is unreliable or even zero (Cnews doesn't maintain it).  This means
that the nnmaster will request a lot of non-existing articles from the
server, causing a lot of network traffic.

To limit this activity, nn will normally only attempt to fetch the
fifty newest articles in each group.  This shouldn't really be a
problem since that will give you enough news to start with, and the
older articles will probably be expired in a few days anyway.

You can change this limit if you like.  Or you can disable this
limitation completely if you trust the min field by giving a 0 limit.

EOF

		ILIMIT=""
		DFLT="none"

		cat <<'EOF'

If the 'min' field in your active file is not reliable, nnmaster can
waste a lot of time trying to locate non-existing articles in the news
groups when it is collecting the available articles the first time it
is started after the database is initialized.  This is especially true
with Cnews where the min field is not normally maintained.

To limit the efforts during the initial collection, you can set a
limit on the number of articles in each group which nnmaster should
try to locate in each group.  This may get you running faster, and it
shouldn't matter much anyway since the articles that may be ignored
will be the oldest articles in the group, and they will probably be
expired soon anyway.  A value in the range 100-500 should be more than
enough.  If you don't specify a limit, all articles will be collected,
but it may take quite some time if the min fields are unreliable.
