  <title>File thumbnails</title>

  <p>If your application handles files which could be printed or could be
  represented well as a document, adding a thumbnailer makes the files show up
  in <app>Files</app> with images that correspond to the document.</p>

  <p>The gnome-desktop library defines the interface and associated files that
  a thumbnailer must implement. The component responsible for calling the
  thumbnailer is <link href="https://developer.gnome.org/gnome-desktop3/stable/GnomeDesktopThumbnailFactory.html">GnomeDesktopThumbnailFactory</link>.</p>

  <p>A common helper for thumbnailers, which handles the command-line parsing
  and output file generation, is <link href="https://github.com/hadess/gnome-thumbnailer-skeleton">gnome-thumbnailer-skeleton</link>.</p>
