/**\r
  UEFI entry point for an application that will in turn call the\r
  ShellAppMain function which has parameters similar to a standard C\r
  main function.\r
\r
  An application that uses UefiShellCEntryLib must have a ShellAppMain\r
  function as prototyped in Include/Library/ShellCEntryLib.h.\r
\r
  Note that the Shell uses POSITIVE integers for error values, while UEFI\r
  uses NEGATIVE values.  If the application is to be used within a script,\r
  it needs to return one of the SHELL_STATUS values defined in Protocol/Shell.h.\r
\r
  @param  ImageHandle  The image handle of the UEFI Application.\r
  @param  SystemTable  A pointer to the EFI System Table.\r
\r
  @retval  EFI_SUCCESS               The application exited normally.\r
  @retval  Other                     An error occurred.\r
