    $0 SOURCES WORKSPACE

Where:
    SOURCES               A directory containing the blktap repository
                          https://github.com/xapi-project/blktap

    WORKSPACE             A workspace to be used. For the initial run, just
                          create an empty directory, and specify the same later

Example:

    git clone https://github.com/xapi-project/blktap
    git clone https://github.com/matelakat/sm-ci
    mkdir workspace
    sm-ci/check-blktap.sh blktap workspace/
