</listitem>        <listitem>          <display_text>Along Route</display_text> - If selected, Maemo          Mapper will download or delete maps along your current route.          This is useful if, for example, you are about to embark on a trip          and want to make sure that you have maps for all points along the          route.        </listitem>        <listitem>          <display_text>Radius (tiles)</display_text> - If          <display_text>Along Route</display_text> is selected, then you can          specify the radius around your route for which maps will be          downloaded or deleted.  For example, if you specify 4 (the          default), then Maemo Mapper will download all tiles that are          within 4 tiles of your route.        </listitem>      </list>      <heading>Zoom</heading>      <para>        The <display_text>Zoom</display_text> tab controls which zoom levels        at which maps are downloaded or deleted.  The current zoom level is        selected by default, but you can enable or disable any zoom levels        that you like.      </para>      <heading>Area</heading>      <para>        The <display_text>Area</display_text> tab, available if the        <display_text>By Area</display_text> option is selected in the        <display_text>Setup</display_text> tab, defines the rectangular area        of the world for which maps will be downloaded or deleted.  If        applicable, the fields are pre-filled with your current and previous        view center coordinates.  This allows you to graphically choose your        rectangle by first centering on one corner of the rectangle, then        centering on the opposite corner, by tapping the screen or by using        the <display_text>Lat/Lon</display_text> menu item of the        <display_text>Go to</display_text> menu.      </para>    </topic>    <topic>      <topictitle>POI Categories</topictitle>      <context contextUID="help_maemomapper_poicat"/>      <para>        POI Categories are a means by which you can organize your POIs for        selective display.  The <display_text>POI Categories</display_text>        dialog is accessed from the <display_text>View</display_text> menu        and allows you to enable/disable, add, edit, or delete categories.      </para>      <para>        Each row in the table represents a category.  There are three        columns displayed for each category:      </para>      <list>        <listitem>          <display_text>Enabled</display_text> - Controls whether or not          POIs in this category are drawn on the map.        </listitem>        <listitem>          <display_text>Label</display_text> - A short label to describe the          category.  This is the name that will be visible when viewing a          POI.        </listitem>        <listitem>          <display_text>Description</display_text> - A longer description of          the category.  This description is not visible anywhere except in          this dialog; it is only used to get an idea of how the category is          meant to be used.        </listitem>      </list>      <para>        Selecting a row in the table and pressing the        <display_text>Edit</display_text> button will allow you to edit the        above three attributes of a category, and to delete a category.  You        can also add a new category by using the        <display_text>Add</display_text> button.      </para>      <note>        A POI may only be associated with a single category at a time.      </note>    </topic>    <topic>      <topictitle>Settings</topictitle>      <context contextUID="help_maemomapper_settings"/>      <para>        The <display_text>Settings</display_text> dialog (accessible from        the main menu) provides access to a plethora of configurable options	that control how Maemo Mapper appears and runs.  In addition to the	tabs, which are described below, there are also two buttons at the	bottom of the diagram labeled <display_text>Hardware	  Keys...</display_text> and <display_text>Colors...</display_text>.      </para>      <para>	The <display_text>Hardware Keys...</display_text> button brings up	another dialog box, which allows you to customize the actions that	each hardware key causes.  For example, you can map the         <graphic filename="2686KEY_esc"/> button to cycle through map	repositories, giving you quick access to switching among them.      </para>      <para>        The <display_text>Colors...</display_text> button allows you to        customize the colors that are used for drawing on-map objects.      </para>      <heading>GPS</heading>      <para>        The <display_text>GPS</display_text> tab tells Maemo Mapper which        bluetooth device from which to retrieve GPS data.  It is only        applicable if you have a bluetooth GPS receiver with which to use        Maemo Mapper.      </para>      <para>        Enter the MAC address in the field provided.  If you don't know the        MAC address, turn on your receiver and press the        <display_text>Scan...</display_text> button to select it from a        list of nearby bluetooth devices.      </para>      <para>        <i>Alternatively</i>, if you are using rfcomm or any other        file-system-based NMEA input source, you can provide a pathname        (beginning with a leading slash) such as "/dev/rfcomm1".  In this        case, Maemo Mapper will read NMEA sentences from the file system        instead of via bluetooth.      </para>      <heading>Auto-Center</heading>      <para>        The <display_text>Auto-Center</display_text> tab allows you to        configure how Maemo Mapper automatically re-centers the display when        either <display_text>Lat/Lon</display_text> or        <display_text>Lead</display_text> is enabled from the        <display_text>Auto-Center</display_text> menu.  The Auto-Center        feature is most useful in conjunction with a GPS receiver.      </para>      <list>        <listitem>          <display_text>Sensitivity</display_text> - Controls how often          Maemo Mapper re-centers the display, based on how close your          position (or the position of your <i>lead</i>) gets to the edge of          the screen.  When set to a low value, Maemo Mapper will only          re-center the screen when you are near the edge of the screen.          When set to the maximum, Maemo Mapper will keep your position as          close to the center as possible.        </listitem>        <listitem>          <display_text>Lead Amount</display_text> - When Auto-Center is set          to <display_text>Lead</display_text>, then Maemo Mapper will keep          the center of the screen focused on an area in front of you.  When          driving, this allows you to view more of the road ahead of you.          The distance in front of you on which the screen is centered is          based on two variables: your current speed and the value of the          <display_text>Lead Amount</display_text> option.        </listitem>      </list>      <heading>Announce</heading>      <para>        The <display_text>Announce</display_text> tab controls how and when        Maemo Mapper displays or speaks waypoint information.  When you        approach a waypoint in your route (defined by the presence of a        description in the GPX file), Maemo Mapper will pop up a text box        with the contents of that description.  When downloading routes from        within Maemo Mapper, the text describes your next action, e.g. "Turn        left at Main Street.  Go 2.4 miles."      </para>      <para>        As you approach a waypoint, Maemo Mapper will continue to display        the description of that waypoint, so long as you are within the        range defined by the <display_text>Advance Notice</display_text>        option, or until you pass the waypoint.  Because the amount of        notice is dependent on your speed, it is possible to see the text,        then slow down to a point where the notice disappears.  This is        possible, for example, if you are stopped at a red light.  The text        will reappear when you have picked up enough speed to again break        the <display_text>Advance Notice</display_text> range.      </para>      <para>        If you have installed <i>flite</i>, which is available in the same        repository from which you downloaded Maemo Mapper, then Maemo Mapper        can optionally also speak the same directions that appear on screen.        Maemo Mapper will only speak the directions once, at the exact        moment you first reach the distance from the waypoint defined by the        <display_text>Advance Notice</display_text> option.  The same        directions are on-screen if you need to reference them.      </para>      <list>        <listitem>          <display_text>Advance Notice</display_text> - Controls how much in          advance Maemo Mapper begins to provide the waypoint description.          The exact distance at which Maemo Mapper begins to announce a          waypoint also depends on your speed, so the value of this option          can be thought of more accurately in units of time.  At the          minimum value, Maemo Mapper gives you almost no notice.  At the          maximum value, Maemo Mapper gives you about two minutes of notice.          Experiment to find your happy medium.        </listitem>        <listitem>          <display_text>Enable Voice Synthesis</display_text> - If you have          installed <i>flite</i>, this option will cause Maemo Mapper to          speak the description of the next waypoint when you enter the          range defined by the <display_text>Advance Notice</display_text>          option.        </listitem>      </list>      <heading>Misc.</heading>      <para>        The <display_text>Misc.</display_text> and <display_text>Misc.          2</display_text> tabs contain miscellaneous options.      </para>      <list>        <listitem>          <display_text>Line Width</display_text> - Controls the thickness          of all lines drawn on top of the map images.  This includes your          mark, all tracks and routes, and the default POI image.        </listitem>        <listitem>          <display_text>Keep Display On Only in Fullscreen            Mode</display_text> - Controls whether or not Maemo Mapper          should limit its "Keep the display on" behavior to full screen          mode only.  If disabled, then Maemo Mapper will always keep the          screen on, as long as you are moving.  If enabled, Maemo Mapper          will only keep the screen on in full screen mode.        </listitem>        <listitem>          <display_text>Information Font Size</display_text> - Controls the          font size for all information that is popped up to the user in the          upper-right corner, including waypoint descriptions.        </listitem>        <listitem>          <display_text>Units</display_text> - Controls the units in which          distances and speeds are displayed in the user interface.        </listitem>        <listitem>          <display_text>Degrees Format</display_text> - Controls how          latitude and longitudes are displayed in the user interface.        </listitem>        <listitem>          <display_text>Speed Limit</display_text> - Enables notification          when you have exceeded the given speed limit (specified in the          units defined via the <display_text>Units</display_text> option.        </listitem>        <listitem>          <display_text>Location</display_text> - Controls the location on          the screen of the speed warning.        </listitem>      </list>      <heading>POI</heading>      <para>        The <display_text>POI</display_text> tab allows you to define your        POI database and how POIs are drawn on the screen.      </para>      <list>        <listitem>          <display_text>POI database</display_text> - The location on the          file system where the POI database is located.  The database must          be in sqlite3 format.  A default (empty) POI database is          automatically created for you when you first run Maemo Mapper.        </listitem>        <listitem>          <display_text>Show POI below zoom</display_text> - Defines the          maximum zoom (furthest away from the Earth) at which POIs will be          drawn.  When zoomed out beyond this level, no POIs will be drawn.        </listitem>      </list>    </topic>    <topic>      <topictitle>About Maemo Mapper</topictitle>      <context contextUID="help_maemomapper_about"/>      <para>        Current Version: __VERSION__      </para>      <para>        Maemo Mapper was created and developed by John Costigan (aka	<display_text>gnuite</display_text>).      </para>      <para>        Copyright 漏 2006-2007 John Costigan.      </para>      <para>        POI and GPS-Info code originally written by Cezary Jackiewicz.      </para>      <para>	Default map data provided by http://www.openstreetmap.org/ - other	map repositories are subject to their own licenses and may or may not	be suitable for use with Maemo Mapper.
