=head1 SYNOPSIS
-B<privoxy-log-parser> [B<--html-output>]
+B<privoxy-log-parser> [B<--detect-inactivity>] [B<--inactivity-threshold msecs>]
+[B<--html-output>]
[B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
[B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
[B<--url-statistics-threshold>] [B<--version>]
=head1 OPTIONS
+[B<--detect-inactivity>] Instead of syntax highlighting, detect periods
+of log inactivity of more than the amount of miliseconds specified with
+the B<--inactivity-threshold> option. Mainly useful for debugging.
+
[B<--host-statistics-threshold>] Only show the request count for a host
if it's above or equal to the given threshold. If the threshold is 0, host
statistics are disabled.
-[B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
+[B<--html-output>] Use HTML and CSS when syntax highlighting. If this option is
omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
This option is only intended to make embedding log excerpts in web pages easier.
It does not escape any input!
-[B<--no-msecs>] Don't expect milisecond resolution
+[B<--inactivity-threshold msecs>] Specifies the number of miliseconds between
+log messages to consider inactivity when running in [B<--detect-inactivity>]
+mode.
+
+[B<--keep-date>] Don't remove the date when printing highlighted log messages.
+Useful when parsing multiple log files at once.
+
+[B<--no-msecs>] Don't expect millisecond resolution
[B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
the filtered output is piped into less in which case the ANSI control
codes don't work, or if the terminal itself doesn't support the control
codes.
+[B<--passed-request-statistics-threshold>] Only show the request count for
+a passed requests if it's above or equal to the given threshold. If the
+threshold is 0, passed request statistics are disabled.
+
[B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
Note that the mapping from thread ids to shortened ids is created at run-time
and thus varies with the input.
