  Abstract:
    Defines the TExternalToolOptions which stores the settings of a single
    external tool. (= Programfilename and parameters)
    All TExternalToolOptions are stored in a TExternalToolList
    (see exttooldialog.pas).
    And this unit provides TExternalToolOptionDlg which is a dialog for editing
    a single external tool.
}
