-# Newslist  $Revision: 37320 $
-#
-# Syntax:
-#    newslist [ -a ]
-#
-# This is a program to create a directory full of HTML pages
-# which between them contain links to all the newsgroups available
-# on your server.
-#
-# The -a option causes a complete list of all groups to be read from
-# the server rather than just the ones which have appeared since last
-# execution. This recreates the local list from scratch. Use this on
-# the first invocation of the program, and from time to time thereafter.
-#   When new groups are first created they may appear on your server as
-# empty groups. By default, empty groups are ignored by the -a option.
-# However, these new groups will not be created again, and so will not
-# appear in the server's list of 'new groups' at a later date. Hence it
-# won't appear until you do a '-a' after some articles have appeared.
-#
-# I should really keep a list of ignored empty groups and re-check them
-# for articles on every run, but I haven't got around to it yet.
-#
-# This assumes an NNTP news feed.
-#
-# Feel free to copy, distribute and modify this code for
-# non-commercial use. If you make any useful modifications, let me
-# know!
