Process this file with an XSLT processor: `xsltproc \

manpages/docbook.xsl manpage.dbk'.  A manual page
<package>.<section> will be generated.  You may view the
manual page with: nroff -man <package>.<section> | less'.  A
typical entry in a Makefile or Makefile.am is:

The xsltproc binary is found in the xsltproc package.  The
XSL files are in docbook-xsl.  Please remember that if you
create the nroff version in one of the debian/rules file
targets (such as build), you will need to include xsltproc
and docbook-xsl in your Build-Depends control field.

    <title>DESCRIPTION</title>

    <para>
      Viking is a program to manage GPS data.
    </para>
    <para>  
      You can import and plot tracks, routes and waypoints, show OpenStreetMap (OSM) maps and/or
      Terraserver maps under it, add coordinate lines, make new tracks, routes and waypoints, hide different things, etc.
      It is written in C with the GTK+ 2 toolkit, available for Linux, other POSIX operating systems and Windows.

    <title>Extending Viking</title>

      <para>Currently, &dhpackage; has some extention points based on configuration files. The file format is heavily inspired by the GtkBuilder file format: you specify the class of the GObject to build and set its properties. Technically, it is a XML file containing a "objects" root element. Inside this element, you set a collection of "object".</para>
      <para>Here is an example:
<literallayout><![CDATA[
<objects>
  <object class="ClassName">
    <property name="property_name1">Property value</property>
    <property name="property_name2">Property value</property>
  </object>
  ...
<objects>
]]>
</literallayout>
</para>
      <para>You can find more examples in the documentation part of the distribution.</para>
