Class
    Foam::sigInt
 
Description
    Signal handler for INT interrupt.
 
    The standard interrupt handler is overridden to ensure that the
    runningJob file is removed.
 
    Can be used either directly through the static member functions or
    through the scope of the object (constructor sets trapping; destructor
    restores original).
