 **
 **  Description     :
 **                      The program mimics - but a lot faster a Jats Makefile fragment
 **                      The program will:
 **
 **                      Operate in two modes
 **                          CopyFile
 **                          DeleteFile
+**                          Remove Files
 **
 **                      CopyFile (5 args)
 **                          1) Display the ----- Text dest
 **                          2) Error if the source is not found
 **                          3) Create target path if not alraedy existing
 **
 **                      DeleteFile (3 args)
 **                          1) Display the ----- Text dest
 **                          2) Delete the target file
 **
+**                      RemoveFiles ( >1 arg)
+**                          1) Silenty delete a list of files. The files may
+**                             be readonly so the attributes will need to be fixed.
+**
 **                      Make paths use '/'
