=back

=head1 DESCRIPTION

B<lr_log2report> reads a log file from STDIN or the specified argument
and will output a formatted Lire report on STDOUT or in the
I<output_file> argument. The format of the log file is specified using
the I<dlf_converter> argument. Use the B<--help dlf-converters> option
to get a list of all currently available DLF converters.

In case the log is passed in a compressed format, it's uncompressed on the fly,
using gzip(1).

WARNING: This command outputs binary data on the terminal for all
output formats except B<txt> and B<xml>. You should redirect
stdout to a file when using those output formats.

In the case where I<output format> is B<html>, the I<output_file> argument will
be interpreted as a directory name.  This directory will get created if needed,
and will hold the various html files.  In case this argument is omitted, a
tar(1) file should be output on STDOUT (but see the BUGS section).

WARNING: Running this command on big logfiles generally means you'll need
lots of free diskspace.  See Lire::LrCommand(3pm) for details.

=head1 EXAMPLES

To process a Postfix log and display the report as text, use

 $ lr_log2report postfix /var/log/mail.log

To process a Postfix log and create an HTML report in a directory, use

 $ lr_log2report -o html postfix /var/log/mail.log postfix-report

=head1 BUGS

If

 --output html

is specified, both I<logfile> and I<output_file> need to be specified.
Specifying C<-> (or C</dev/stdin>) as I<logfile> is supported.  So this

 $ tai64nfrac < /var/log/qmail-send/current | \
    lr_log2report qmail --output html - /tmp/report

will work.
