=head1 NAME

ptee - multicast your logs

=head1 VERSION

This document refers to version 1.0003 of ptee

=head1 PURPOSE

Use this program somewhat like the unix tee(1) command, to send text input to
multiple destinations, for example a log file, Syslog, and so on.


The unix tee(1) command accepts text on standard input, and emits that same
text back out on standard output whilst also appending it to a log file.

This program is similar, but more flexible, in that you can specify other
destinations, and have as many as you like. By default it operates in
pass-through mode; text received is simply emitted straight back out on
standard output.

=head1 USAGE

Configuration is provided in the format used by the Perl module
L<Log::Dispatch::Config>. This is a wrapper around the excellent
L<Log::Dispatch> perl module, which is the tool that provides all your output

The best thing to do is read the manual page for these two modules - don't
worry they are not complicated. Once you have done that, you can write your
own configuration file.

You can use many different formats of configuration file. Please read the
L<Config::Any> Perl module manual for more details. Here is a simple example
which will emit logs to standard output and a file, much like the unix utility

 dispatchers : [file, screen]
   class : 'Log::Dispatch::File'
   min_level : debug
   filename : '/path/to/log'
   mode : append
   format : '[%d] [%p] %m at %F line %L%n'
   class : 'Log::Dispatch::Screen'
   min_level : info
   stderr : 1
   format : '%m'

The above file is in YAML format, a good choice, and so if you save this as
C</etc/ptee.yml> it will be loaded and used.

Alternatively, you can specify the file name in the C<PTEE_CONFIG> environment
variable, or as the first command line parameter to C<ptee> itself. This gives
you the ability to use a different file format, but please read the manual
page for the L<Log::Dispatch::Configurator::Any> Perl module in that case to
avoid a couple of minor pitfalls.
