       Read XMLTV data and write out the same data sorted in date order.  Where stop times of programmes are
       missing, guess them from the start time of the next programme on the same channel. For the last programme
       of a channel, no stop time can be added.

       Tv_sort also performs some sanity checks such as making sure no two programmes on the same channel
       overlap.

       --outputFILE write to FILE rather than standard output

       --by-channel sort first by channel id, then by date within each
                       channel.

       --duplicate-error If the input contains the same programme more than once,
                            consider this as an error. Default is to silently
                            ignore duplicate entries.

       The time sorting is by start time, then by stop time.  Without --by-channel, if start times and stop
       times are equal then two programmes are sorted by internal channel id.  With --by-channel, channel id is
       compared first and then times.

       You can think of tv_sort as converting XMLTV data into a canonical form, useful for diffing two files.

       At a typical Unix shell or Windows command prompt:

       tv_sort <in.xml >out.xml
       tv_sort in.xml --output out.xml

       These are different ways of saying the same thing.
