/*

BUG ECKIT-175
=============

    when Main::initialise(argc,argv) is *not*
    called or a Tool is *not* used,
    then everything is OK, and the 
    FileTarget gets destructed as opposed to
    when Main::initialise(argc,argv) *is* called,
    or a Tool *is* used.

    Program expects an integer argument. Possible values: 
    0 :
        Test does *not* initialise a Main::instance()
        Everything works as expected.

    1 :
        Test explicitely starts with Main::initialise(argc,argv)
        Buffers should be flushed but aren't
    2 :
        Test uses a eckit::Tool to initialise a Main::instance()
        Buffers should be flushed but aren't

Note:
    The destructor ~FileTarget() is modified to print
    a message when invoked, so don't merge this
