package Transfer

    ---Purpose : Defines general Transfer engine, which provides tools and
    --           workframe for all kinds of file (non-direct) Interfaces.
    --           Works on the basis of data provided by package Interface
    --           (especially InterfaceModel).

uses TCollection, TColStd, MMgt, Standard, Dico, MoniTool, Interface,  Message

    ---Purpose : execution status of an individual transfer (see Transcriptor)

    ---Purpose : used on processing Undefined Entities (see TransferOutput)
