101----------
102Things left to do:
103
1041) Setup an INN feed to feedlog.pl
105
106 a) Edit your 'newsfeeds' file and insert something like
107
108 ## gather statistics for NewsStats
109 newsstats!\\
110 :!*,de.*\\
111 :Tc,WmtfbsPNH,Ac:$Path/feedlog.pl
112
113 Please
114
115 * check that you got the path to feedlog.pl right
116 * check that feedlog.pl can be executed by the news user
117 * adapt the pattern (here: 'de.*') to your needs
118
119 b) Check your 'newsfeeds' syntax:
120
121 # ctlinnd checkfile
122
123 and reload 'newsfeeds':
124
125 # ctlinnd reload newsfeeds 'Adding newsstats! feed'
126
127 c) Watch your 'news.notice' and 'errlog' files:
128
129 # tail -f /var/log/news/news.notice
130 ...
131 # tail -f /var/log/news/errlog
132
1332) Watch your $Conf{'DBTableRaw'} table fill.
134
1353) Read the documentation. ;)
136
137Enjoy!

143if ($OptUpdate) {
144 $Upgrade = <<UPGRADE;
145----------
146Your installation was upgraded from $OptUpdate to $PackageVersion.
147
148Don't forget to restart your INN feed so that it can pick up the new version:
149
150 # ctlinnd begin 'newsstats!'
151
152(or whatever you called your feed).
