  <chapter id="Buildin-HPCC-from-Source">
    <title>Using Configuration Manager</title>

    <para>Configuration Manager is the utility with which we configure the
    HPCC platform. The HPCC platform's configuration is stored in an XML file
    named <emphasis role="bold">environment.xml</emphasis>. When you install a
    package, a default single-node environment.xml is generated. After that,
    you can use the Configuration Manager to modify it and add nodes and
    configure components.</para>

    <para>The Configuration Manager Wizard creates a similar file, but after
    it is generated, you must rename it and put it into place on each
    node.</para>

    <para>Configuration Manager also offers an <emphasis role="bold">Advanced
    View</emphasis> which allows you to add instances of components or change
    the default settings for components. Even if you plane to use Advanced
    View, it is a good idea to start with a wizard generated configuration and
    use Advanced View to finish it.</para>

    <para>This document will guide you through configuring an HPCC environment
    using the Configuration Manager.</para>

                  <entry>Keep in mind, that your HPPC configuration may be

                  In addition, in a production [Thor] system, you would ensure
