        <section id='build-dependencies'>
            <title>Build Dependencies</title>

            <para>
                BitBake uses the
                <link linkend='var-DEPENDS'><filename>DEPENDS</filename></link>
                variable to manage build time dependencies.
                The "deptask" varflag for tasks signifies the task of each
                item listed in <filename>DEPENDS</filename> that must
                complete before that task can be executed.
                Here is an example:
                <literallayout class='monospaced'>
     do_configure[deptask] = "do_populate_sysroot"
                </literallayout>
                In this example, the <filename>do_populate_sysroot</filename>
                task of each item in <filename>DEPENDS</filename> must complete before
                <filename>do_configure</filename> can execute.
            </para>
        </section>


        <section id='runtime-dependencies'>
            <title>Runtime Dependencies</title>

            <para>
                BitBake uses the
                <link linkend='var-PACKAGES'><filename>PACKAGES</filename></link>,
                <link linkend='var-RDEPENDS'><filename>RDEPENDS</filename></link>, and
                <link linkend='var-RRECOMMENDS'><filename>RRECOMMENDS</filename></link>
                variables to manage runtime dependencies.
            </para>

            <para>
                The <filename>PACKAGES</filename> variable lists runtime
                packages.
                Each of those packages can have <filename>RDEPENDS</filename> and
                <filename>RRECOMMENDS</filename> runtime dependencies.
                The "rdeptask" flag for tasks is used to signify the task of each
                item runtime dependency which must have completed before that
                task can be executed.
                <literallayout class='monospaced'>
     do_package_qa[rdeptask] = "do_packagedata"
                </literallayout>
                In the previous example, the <filename>do_packagedata</filename>
                task of each item in <filename>RDEPENDS</filename> must have
                completed before <filename>do_package_qa</filename> can execute.
            </para>
        </section>


so again, RDEPENDS isn't good enough for build time dependencies
