package Interface

    ---Purpose : defines a general frame for interface data
    --           used to manipulate results of normalized Interface outputs
    --           (i.e. files), also as a basis to define transfer operations
    --           (in other packages : see package Transfer)

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