 (* Traces

    "Santity Check Strict":
    ------------------------
    Turn warnings or exception on or off.
    Default: true (through exception)

    "Santity Check Verbose":
    ------------------------
    Turn verbose reporting on or off.
    Default: true


    "Santity Check Free Vars":
    --------------------------
    Turn checking for free top-level variables to different levels:
      0 : allow no free vars
      1 : if theorem starts with an allquantor, then allow no free vars
      2 : no check
    Default: 1


    "Santity Check Var-Const Clash":
    --------------------------------
    Turn checks whether constant names are used as variables on or off.
    Default: true


    "Santity Check Thm-Name Clash":
    -------------------------------
    Turn checks whether the same theorem name is used in multiple theories.
    Default: true
