    +Brooklyn remote install script.
    +
    +Options
    +
    +    -q  Quiet install
    +    -s  Create and set up user account (set with -u option)
    +    -e  Set up random entropy for SSH
    +    -g  Generate a password for the Brooklyn admin user
    +    -u  Change the Brooklyn username (default 'brooklyn')
    +    -r  Change the remote root username (default 'root')
    +    -k  The private key to use for SSH (default '~/.ssh/id_rsa')
    +    -p  The SSH port to connect to (default 22)
    +    -v  Set the Brooklyn version to install (default '0.7.0-M1')
    +
    +Usage

    +    brooklyn-install.sh [-q] [-s] [-e] [-g] [-u user] [-r root] [-k key] [-p port] [-v
version] hostname
    +
    +Installs Brooklyn on the given hostname as 'brooklyn' or the specified
