    !   this is a major bug and/or lack of functionality and should be fixed
        ASAP.
    +   this is potentially useful enchancement.
    -   minor improvement.


 So, current TODO is:

    +   port to *BSD family and other UN*X systems. I neither know nor use any
        of them, so every help is welcome.
    +   give info about command execution result.
    -   optionally, die after first execution of given command..
