+ The fileTransfer and fileRef interfaces provide a file transfer service
+ between different computers.
+
+ A fileRef object is associated to an original file (origFileName) on a
+ machine (refMachine).
+ It is created by a container (factoryServer) on refMachine,
+ with createFileRef(in string origFileName) method.
+ The fileRef object maintains a list of (machine,filename) for copies.
+ If a copy exists on myMachine, getRef(myMachine) returns the file name
+ of the copy on myMachine, else returns empty string.
+ If there is no copy on myMachine, method getFileTransfer() from container
+ factoryServer on refMachine provides a fileTransfer object dedicated to
+ CORBA file copy.
+ After the copy, addRef(myMachine, localFileNameOnMyMachine) registers
+ the file name of the copy on myMachine.
