**  Project/Product : 

**  Filename        : CopyFile.c

**  Author(s)       : DDP

**

**  Description     :

**                      The program mimics - but a lot faster a Jats Makefile fragment

**                      The program will:

**

**                      Operate in two modes

**                          CopyFile

**                          DeleteFile

**

**                      CopyFile (5 args)

**                          1) Display the ----- Text dest

**                          2) Error if the source is not found

**                          3) Create target path if not alraedy existing

**                          4) Copy the source to the target - overwritting the target

**                          5) Set File mode

**                          6) Test for file existence

**

**                      DeleteFile (2 args)

**                          1) Display the ----- Text dest

**                          2) Delete the target file

**

**                      Make paths use '/'
