    <title>Adding Individual Packages to the Standard SDK</title>

    <para>
         When you build a standard SDK using the
         <filename>bitbake -c populate_sdk</filename>, a default set of
         packages is included in the resulting SDK.
         The
         <ulink url='&YOCTO_DOCS_REF_URL;#var-TOOLCHAIN_HOST_TASK'><filename>TOOLCHAIN_HOST_TASK</filename></ulink>
         and
         <ulink url='&YOCTO_DOCS_REF_URL;#var-TOOLCHAIN_TARGET_TASK'><filename>TOOLCHAIN_TARGET_TASK</filename></ulink>
         variables control the set of packages adding to the SDK.
    </para>

    <para>
        If you want to add individual packages to the toolchain that runs on
        the host, simply add those packages to the
        <filename>TOOLCHAIN_HOST_TASK</filename> variable.
        Similarly, if you want to add packages to the default set that is
        part of the toolchain that runs on the target, add the packages to the
        <filename>TOOLCHAIN_TARGET_TASK</filename> variable.
    </para>

<section id='adding-api-documentation-to-the-standard-sdk'>
    <title>Adding API Documentation to the Standard SDK</title>

    <para>
        You can include API documentation as well as any other
        documentation provided by recipes with the standard SDK by
        adding "api-documentation" to the
        <ulink url='&YOCTO_DOCS_REF_URL;#var-DISTRO_FEATURES'><filename>DISTRO_FEATURES</filename></ulink>
        variable:
        <literallayout class='monospaced'>
     DISTRO_FEATURES_append = " api-documentation"
        </literallayout>
        Setting this variable as shown here causes the OpenEmbedded build
        system to build the documentation and then include it in the standard
        SDK.
