Welcome to AEOS (Ångström based, Yocto Project Compatible Distribution)

For more information about OpenEmbedded see their website:
    http://www.openembedded.org/

Your build environemnt has been configured with:

    MACHINE=${MACHINE}
    SDKMACHINE=${SDKMACHINE}
    DISTRO=${DISTRO}

You can now run 'bitbake <target>'
