+=head1 NAME
+
+tsplot - plot time series in column format
+
+=head1 SYNOPSIS
+
+tsplot
+[--dbname dbname]
+[--finalresolution dpi]
+[--legend-position pos]
+[--output-format format ]
+[--stacked]
+[--style style]
+[--time_t]
+[--yrange min max]
+[query ...]
+
+=head1 DESCRIPTION
+
+This program expects time series data in column format, I.e.,
+each line contains a timestamp and the values for each series, except
+the first one which contains the column headers, which are used for the
+legend. Columns are separated by any amount of whitespace unless the
+--tsv option is given which enables tab-separated columns.
+
+The default legend position is "top right", same as with gnuplot.
+Another frequently useful position (especially if you have lots of series)
+is "below". Note that positions which consist of several words (such as
+"top right") need to be passed to tsplotv as a single argument, so the 
+space needs to be hidden from the shell by use of quotes or a backslash.
+
+The default output format is "png", the default style is "lines".
+
+See L<TimeSeries> for a description of possible legend positions,
+output formats, and styles.
+
+The --stacked option causes the time series to be stacked on top of each
+other.
+
+The --time_t option specifies that the timestamps are in seconds since
+the epoch. Otherwise they are parsed by add_timestring function (which
+in turn uses the parse_date function of the HTTP::Date module).
