    <para>If you'd like to import binary Pepper plugins from Chrome, you'll
    need to enable PNaCL. PNaCL is a sandboxed environment for running
    untrusted code, but the binary toolchain is availalbe only on x86_64.
    Download the binary PNaCL toolchain with the following commands:</para>

<screen><userinput>python build/download_nacl_toolchains.py --packages \
    nacl_x86_newlib,pnacl_newlib,pnacl_translator \
    sync --extract</userinput></screen>

<!--    <para>If on any other arch than x86_64, you will have to build the PNaCL
    environment yourself. Please report if this works without issue as this
    has not been tested. Instuctions were taken directly from
    <ulink url="https://www.chromium.org/nativeclient/pnacl/building-pnacl-components-for-distribution-packagers">
    here</ulink>. Note that Google no longer support i686 builds, so any
    plugin extracted from the binary installation of Chrome (libwidevinecdm.so)
    will be necessarely out of date.</para>

    <para>To enable use of

    support (see the binary Chrome plugins section below), in addition to
    enabling PNaCL above, you'll need to define an availalbe product name
    ("Pinkie Pie" in this case) with the following command:</para>

<screen><userinput>sed "s/WIDEVINE_CDM_AVAILABLE/&amp;\n\n#define WIDEVINE_CDM_VERSION_STRING \"Pinkie Pie\"/" \

        Chromium uses many exteranl projects, the selections below are not set
        in stone, however they have been tested thoroughly. With 53.0.2785.116,
        system versions of icu, libxml2, libvpx, and zlib are known to break
        the build at this time.</para>

        specific to LFS. If using these instructions for another distro, or if
