| 94 | feedlog - log data from an INN feed to a database |
| 95 | |
| 96 | =head1 SYNOPSIS |
| 97 | |
| 98 | B<feedlog> [B<-Vhdq>] |
| 99 | |
| 100 | =head1 REQUIREMENTS |
| 101 | |
| 102 | See doc/README: Perl 5.8.x itself and the following modules from CPAN: |
| 103 | |
| 104 | =over 2 |

| 119 | |
| 120 | =head1 DESCRIPTION |
| 121 | |
| 122 | This script will log overview data and complete headers to a database |
| 123 | table for further examination by parsing a feed from INN. It will |
| 124 | parse that information and write it to a mysql database table in real |
| 125 | time. |
| 126 | |
| 127 | All reporting is done to I<syslog> via I<news> facility. If B<feedlog> |
| 128 | fails to initiate a database connection at startup, it will log to |
| 129 | I<syslog> with I<CRIT> priority and go in an endless loop, as |
| 130 | terminating would only result in a rapid respawn. |
| 131 | |
| 132 | =head2 Configuration |
| 133 | |
| 134 | F<feedlog.pl> will read its configuration from F<newsstats.conf> which |
| 135 | should be present in the same directory via Config::Auto. |
| 136 | |
| 137 | See doc/INSTALL for an overview of possible configuration options. |
| 138 | |
| 139 | =head1 OPTIONS |
| 140 | |
| 141 | =over 3 |
| 142 | |
| 143 | =item B<-V> (version) |
| 144 | |
| 145 | Print out version and copyright information on B<yapfaq> and exit. |
| 146 | |
| 147 | =item B<-h> (help) |
| 148 | |
| 149 | Print this man page and exit. |
| 150 | |
| 151 | =item B<-d> (debug) |
| 152 | |
| 153 | Output debugging information to STDERR while parsing STDIN. You'll |
| 154 | find that information most probably in your B<INN> F<errlog> file. |
| 155 | |
| 156 | =item B<-q> (quiet) |
| 157 | |
| 158 | Suppress logging to syslog. |
