.SH NAME
htsn \- Parse XML files from The Sports Network feed.

.SH SYNOPSIS

\fBhtsn\fR [OPTIONS] [HOSTNAMES]

.SH DESCRIPTION
.P
The Sports Network <http://www.sportsnetwork.com/> offers an XML feed
containing various sports news and statistics. The goal of \fBhtsn\fR
is to watch the XML feed and parse the individual XML documents into
files.
.P
Once started, we will choose an XML feed host to connect to. The
choice is made from a list in a round-robin fashion, and by default,
the list contains all known TSN feed hosts. Once we have a connection,
your username and password are sent. If they are accepted, we begin to
parse the feed saving all XML files to the configured output directory
(see \fI\-\-output\-directory\fR).
.P
If we encounter an error (say, the connection is dropped), then we
will attempt to connect to the next host in the list after waiting
five seconds. This process continues indefinitely.
.P
The program can run either interactively (that is, outputting to the
console), or as a daemon with the \fI\-\-daemonize\fR flag.

.SH INPUT
.P
The program takes no input; a username and password must be supplied
on the command-line or in a configuration file.

.SH OUTPUT
.P
Output is not generated when running as a daemon; otherwise, standard
out and standard error are fairly noisy. All traffic between htsn and
the feed server is displayed on stdout. Status messages are
interspersed when they are generated with warnings and errors going to
stderr. The following can be expected:
.IP \[bu] 2
The only data we send to the feed are the username and password. These
will be highlighted in green on stdout.
.IP \[bu]
All data received from the feed will be echoed in the default color to
stdout.
.IP \[bu]
Informational messages will be highlighted in cyan and sent to stdout.
.IP \[bu]
Warnings will be highlighted in yellow and sent to stderr.
.IP \[bu]
Errors will be highlighted in red and sent to stderr.

.SH LOGGING
.P
Logging is done either to syslog or a file. The destination and
verbosity are controlled by the \fI\-\-log\-file\fR,
\fI\-\-log\-level\fR, and \fI\-\-syslog\fR parameters which may be
specified either on the command line or in the configuration file.

.SH OPTIONS

.IP \fB\-\-daemonize\fR,\ \fB\-d\fR
Run as a daemon, in the background. When running as a daemon the
\fI\-\-pidfile\fR, \fI\-\-run\-as\-group\fR, and
\fI\-\-run\-as\-user\fR flags become relevant.

Default: disabled

.IP \fB\-\-log-file\fR
If you specify a file here, logs will be written to it (possibly in
addition to syslog). Can be either a relative or absolute path. It
will not be auto-rotated; use something log logrotate for that.

Default: none

.IP \fB\-\-log-level\fR
How verbose should the logs be? We log notifications at three levels:
INFO, WARN, and ERROR. Specify the \(dqmost boring\(dq level of
notifications you would like to receive (in all-caps); more
interesting notifications will be logged as well.

Default: INFO

.IP \fB\-\-output\-directory\fR,\ \fB\-o\fR
To which directory should we write the XML files?

Default: .

.IP \fB\-\-password\fR
The password associated with your TSN username. A password is
required, so you must supply one either on the command line or in a
configuration file.

Default: none

.IP \fB\-\-pidfile\fR
(Daemon mode only) Create a PID file in the given location. This is
used by the init system on Unix to keep track of the running daemon.
Its parent directory must be writable by the user/group that we will
run as!

Default: /run/htsn/htsn.pid

.IP \fB\-\-run\-as\-group\fR
(Daemon mode only) Run as the given system group. The PID file is
written before privileges are dropped, so the only privileges needed
by htsn are those necessary to write the XML files and (optionally)
the log file.

Default: the current group

.IP \fB\-\-run\-as\-user\fR
(Daemon mode only) Run as the given system user. The PID file is
written before privileges are dropped, so the only privileges needed
by htsn are those necessary to write the XML files and (optionally)
the log file.

Default: the current user

.IP \fB\-\-syslog\fR,\ \fB\-s\fR
Enable logging to syslog. On Windows this will attempt to communicate
(over UDP) with a syslog daemon on localhost, which will most likely
not work.

Default: disabled

.IP \fB\-\-username\fR,\ \fB\-u\fR
Your TSN username. A username is required, so you must supply one
either on the command line or in a configuration file.

Default: none

.SH FEED HOSTS
.P
It is possible to pass a list of feed hostnames on the command-line
(see [HOSTNAMES] in the synopsis). By default \fBhtsn\fR will attempt
to connect to every known TSN XML feed host in a round-robin fashion,
so there is rarely a need to do this.

.SH CONFIGURATION FILE
.P
Any of the command-line options mentioned above can be specified in a
configuration file instead. We first look for \(dqhtsnrc\(dq in the
system configuration directory (/etc on Unix). We then look for a file
named \(dq.htsnrc\(dq in the user's home directory. The latter will
override the former.
.P
The file's syntax is given by examples in the htsnrc.example file
(included with \fBhtsn\fR).
.P
Options specified on the command-line override those in either
configuration file.
