    <title>Obtaining Kolab Software</title>
    <para>
        Kolab is built out of the best available Free and Open Source software components, most if not all of which are available through the Linux distribution of your preference. However, such Linux distribution may not be as up-to-date as one might wish for the Kolab Groupware to provide the latest and greatest functionality, or may simply have a different update policy from what is typically acceptable for a Groupware environment. Kolab therefor provides two alternative deployment methods;

        <title>Installation with OpenPKG</title>
        <para>
            OpenPKG is a package management system based on RPM, allowing the Kolab product components to be provided as one set of packages with all functionality included, in one single go, for all platforms supported by OpenPKG &mdash;including most Linux-based operatig systems.

        <para>
            While there certainly are advantages to OpenPKG, it also has a few major downsides:
        </para>
        <simplelist>
            <member> OpenPKG has become proprietary. </member>
            <member> Native packaging efforts have been undertaken by various community members. </member>
            <member> Kolab Groupware through OpenPKG maintained its own copy of the complete dependency stack. </member>

            <para>
                OpenPKG, as a delivery method for Kolab, will be deprecated with 3.0 series releases. Please refer to the native packaging sections in this guide for instructions on native packages provided by Kolab.
