      7 # Requires: nothing beyond a POSIX shell -- the file is plain text and is
      8 # written out literally, so the result is byte-for-byte reproducible.
      9 #
     10 # The file is an OGC KML 2.2 document that exercises what the kml plugin
     11 # parses: the document name and an HTML-bearing CDATA description, an
     12 # atom:author and atom:link, a <LookAt> (the *viewer's* position, which
     13 # the plugin must not confuse with the data), a <TimeStamp>, three
     14 # Placemarks -- two points and one LineString -- and a <NetworkLink>,
     15 # which is the forensically interesting bit because it means opening the
     16 # file fetches something from a remote host.
     17 #
     18 # The data is invented (the same Zurich walk as gpx_test.gpx, so that the
     19 # two plugins can be compared) and is dedicated to the public domain
     20 # (CC0).  Note that KML coordinates are lon,lat[,alt] -- the reverse of
     21 # the GPX attribute order.
