      <para>Welcome to Maemo Mapper.</para>
      <para>
        Maemo Mapper is a geographical mapping tool that can be used to:
      </para>
      <list>

      <para>
        When you first start Maemo Mapper, you will be presented with the
        <display_text>Settings</display_text> dialog box.  Most of the
        settings have reasonable defaults, but if you have a GPS receiver,
        you should fill in the <display_text>MAC</display_text> field with
        the MAC address of your GPS receiver.  If you don't know the MAC,
        turn on your GPS receiver and push the
        <display_text>Search</display_text> button.  Maemo Mapper will
        attempt to automatically discover the MAC address of your receiver.
        For more information about the <display_text>Settings</display_text>
        dialog box, see <ref refid="help_maemomapper_settings"
          refdoc="Settings"/>.
      </para>
      <para>
        When you are finished setting up Maemo Mapper to your preferences,
        pressing the <display_text>Ok</display_text> button will lead you to
        another dialog box: the <display_text>Manage
          Repositories</display_text> dialog.
      </para>
      <para>
        To get started quickly, press the
        <display_text>Download...</display_text> button.  Maemo Mapper will
        download a set of pre-defined repository information for you to use.
        If you use the pre-defined repositories, you can delete the
        <display_text>Default</display_text> repository.  For more
        information about repositories and the <display_text>Manage
          Repositories</display_text> dialog, see
        <ref refid="help_maemomapper_repoman"
          refdoc="Managing Repositories"/>.
      </para>
      <para>
        Certain repositories (most notably, the commercial ones) may have
        license agreements attached with their use.  It may be illegal to
        use a certain repository with Maemo Mapper or under certain
        conditions.  This includes the repositories downloaded via the
        <display_text>Download...</display_text> button.  If you are not
        sure if you are legally allowed to use a particular repository, you
        should delete it from your list of repositories.  The authors of
        Maemo Mapper cannot be held responsible for your use of a particular
        repository.
      </para>
      <para>
        Once you have your Repositories set up the way you like, press the
        Ok button, and you will be presented with a blank screen, because
        you have not yet actually downloaded any map data to your device.
        To allow Maemo Mapper to automatically download map data as it
        becomes needed on the display, enable the
        <display_text>Auto-Download</display_text> checkbox in the
        <display_text>Maps</display_text> menu.
      </para>
      <para>
        If you have a working internet connection, Maemo Mapper will attempt
        to download maps and display them on the screen automatically as
        the downloads complete.  You should see a map of the world.  Be
        careful when you enable Auto-Download, because it can quickly fill
        your available disk space.  See
        <ref refid="help_maemomapper_mapman" refdoc="Managing Maps"/> for
        details on how to manage disk space for a particular repository.
      </para>
      <heading>The Graphical User Interface</heading>
      <para>
        The main view of Maemo Mapper emphasizes simplicity.  By default,
        the map is all that is displayed.  You current position (if you have
        a GPS receiver) is indicated by a blue circle.  The blue line
        extending from the blue circle indicates your current heading and
        speed.  <i>Tracks</i> are red and represent where you have been.
        <i>Routes</i> are green and represent where you want to go, i.e.
        directions to a location.

        </listitem>
      </list>
      <para>
        You can also pan around the map by tapping on the screen.  Maemo
        Mapper will center the display on where you tapped.  If you had
        <display_text>Auto-Center</display_text> enabled, tapping a location
        to center on it will automatically disable that functionality.
      </para>
      <para>
        From this point, you can use the menus to manage routes, tracks, and
        map data; to change the view; to change settings; or to see detailed
        GPS information (if you have a GPS receiver).
      </para>
      <para>
        There is also a context-sensitive menu that appears on the map when
        you tap and hold a location on the map.  From that menu, you can
        download directions, calculate distances, or add/modify
        Point-of-Interest (POI) data.

        This help topic describes the functionality of each of the menu
        items in Maemo Mapper.
      </para>
      <heading>Route</heading>
      <para>
        The <display_text>Route</display_text> menu is used to manipulate
        the current <i>route</i>.  A route in Maemo Mapper is defined as a
        set of points and waypoints describing <i>where you would like to
          go</i>, e.g. driving directions from 123 Main Street to 456 Elm
        Street.  It can include multiple segments.  The current route is
        empty until you open or download a route.
      </para>
      <para>
        The <display_text>Route</display_text> menu has the following menu
        items:
      </para>
      <list>
        <listitem>
          <display_text>Open...</display_text> - Open a route from a GPX
          file on the file system.  The opened route is <i>appended</i> to
          the current route, so you can string together different routes
          together to create a trip with multiple destinations.
        </listitem>
        <listitem>
          <display_text>Download...</display_text> - Download a route from
          the internet.  See <ref refid="help_maemomapper_downroute"
            refdoc="Download Route"/> for more information.
        </listitem>
        <listitem>
          <display_text>Save...</display_text> - Save the current route to a
          GPX file on the file system.
        </listitem>
        <listitem>
          <display_text>Show Distance to Next Waypoint</display_text> - Show
          the distance left to be traveled (along the current route) until
          the next waypoint.
        </listitem>
        <listitem>
          <display_text>Show Distance to End of Route</display_text> - Show
          the distance left to be traveled (along the current route) until
          the end of the current route.  The calculated distance includes
          the distance between breaks in the route (i.e. between the end of
          one route segment and the beginning of another route segment).
        </listitem>
        <listitem>
          <display_text>Reset</display_text> - Reset Maemo Mapper's tracking
          of your progress along the current route.  Use this if Maemo
          Mapper loses track of where you are with respect to the current
          route.
        </listitem>
        <listitem>
          <display_text>Reset</display_text> - Clear the current route,
          effectively replacing it with an empty route.
        </listitem>
      </list>
      <heading>Track</heading>
      <para>
        The <display_text>Track</display_text> menu is used to manipulate
        your current <i>track</i>.  A track in Maemo Mapper is defined as
        a set of points along which you have been traveling, i.e.  <i>where
          you have been</i>.  It can include multiple segments.  Tracks are
        most useful if you have enabled a GPS receiver.  The current track
        is empty until you get at least one valid position point from your
        GPS receiver, and it is appendeded to whenever you stray far enough
        from the last track point.
      </para>
      <para>
        The <display_text>Track</display_text> menu has the following menu
        items:
      </para>
      <list>
        <listitem>
          <display_text>Open...</display_text> - Open a track from a GPX
          file on the file system.  In contrast to route data, the opened
          track is <i>prepended</i> to the current track, so if you are
          trying to rebuild previous track data, you must open the tracks
          backward in time (most recent tracks first).
        </listitem>
        <listitem>
          <display_text>Save...</display_text> - Save the current track to a
          GPX file on the file system.
        </listitem>
        <listitem>
          <display_text>Insert Break</display_text> - Artificially insert a
	  break in your current track data.  This simulates the loss and
	  re-acquisition of a GPS fix, and it can be used to track, for
	  example, refueling stops.
        </listitem>
        <listitem>
          <display_text>Insert Mark</display_text> - Artificially insert a
	  mark with a description in your current track data.  This can be
	  used to mark important landmarks.
        </listitem>
        <listitem>
          <display_text>Show Distance from Last Break</display_text> - Show
          the distance traveled (along the current track) since the last
          break.
        </listitem>
        <listitem>
          <display_text>Show Distance from Beginning</display_text> - Show
          the distance traveled (along the current track) since the
          beginning of the track.  The calculated distance includes the
          distance between breaks in the track (i.e. between when a GPS fix
          is lost and later re-acquired).
        </listitem>
        <listitem>
          <display_text>Clear</display_text> - Clear the current track,
          effectively replacing it with an empty track.
        </listitem>
      </list>
      <heading>Maps</heading>
      <para>
        The <display_text>Maps</display_text> menu is used to control your
        map repositories.  This menu will be populated with a list of all of
        your map repositories, from which you can select to switch to a
        particular repository.
      </para>
      <para>
        The <display_text>Maps</display_text> menu has the following menu
        items in addition to the list of available repositories:
