-o   Overwrite Output File if it Exists

This option is used when you specify a  destination file (output file) on the
command line.  If a file with the same name as the output file that  you have
specified  already exists at the destination, it will  automatically be over-
written when you use this command. If you do not use this option, PKLITE will
prompt you for confirmation before it overwriting  any existing output  file.

         C:\PKWARE> PKLITE  -o  PROG.EXE  A:\TINYPROG.EXE

In the example shown above, PKLITE will compress PROG.EXE and will locate the
compressed version of the program on the A: drive.  The compressed version of
the program will be named TINYPROG.EXE. If a file called TINYPROG.EXE already
exists on  the A: drive, it will automatically be overwritten.

NOTE:  The -o option is only necessary if a output file is specified.
