Check a given sm repository

Usage:
    $0 SM_SOURCES WORKSPACE

Where:
    SM_SOURCES            A directory containing the storage manager repository
                          https://github.com/xapi-project/sm

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