PKLITE is an easy to use file compression program.  All of the commands used
with PKLITE  are entered on the command line at  the DOS prompt. The command
options used with  PKLITE are explained  in detail in the following section,
along with examples.


The PKLITE command line structure is shown below.


PKLITE  [options] [d:][path] Infile  [[d:][path] Outfile]


     PKLITE = The PKWARE executable compression program.

     options = The different PKLITE options that you can specify.

     [d:] [path] Infile = The name and path location of the
          executable file being compressed (or expanded),
          also know as the source file.

     [d:] [path] Outfile = The name and path location of the
          destination file you want to rename or to
          relocate the compressed or expanded file.


     NOTE:  Parameters listed in [ ] are optional.


EXAMPLES:

A simple example is shown below.

C:\DOS> PKLITE  attrib.exe

In this  example the file  attrib.exe will be  compressed and the compressed
version of the file will overwrite the original version.  After you type the
command shown above,  PKLITE will display the  following information on  the
screen.


     PKLITE (tm)  Executable File Compressor.  Version 1.00
     Copyright 1990  PKWARE Inc.  All Rights Reserved.

     Compressing  attrib.exe
     Original Size: 10656  Compressed Size: 6790   Ratio: 36.3


After a file is compressed with  PKLITE, it  will display  several  pieces of
important  information.  PKLITE will  list the  name  of  the original  file,
original size of  the file, the  compressed  size, and the compression ratio.
The output filename and  location  will also be  listed if they are different
than the original filename and location.  An example is shown below.


The following example illustrates the use of an output file to change the name
and location of the file after it is compressed.


C:\> PKLITE  light.exe  A:smlight.exe

PKLITE (tm)  Executable File Compressor.  Version 1.00
Copyright 1990  PKWARE Inc.  All Rights Reserved.

Compressing: LIGHT.EXE into file A:SMLIGHT.EXE
Original Size: 18466   Compressed Size: 12299   Ratio: 33.4


Summary (below) of important facts to keep in mind while using PKLITE.

     -The commands can be typed using either upper case or lower case.

     -All command options for the software must be preceded by a '-'
      character or the MS-DOS switch character (usually '/').

     -Options can be combined (i.e. "-o -b" or "-ob").

     -If no extension for the source file is specified, PKLITE will
      automatically compress any files with that particular name and a
      .EXE or .COM extension.

     -If no destination file is listed on the command line, the
      compressed file will have the same name as the source file and
      will be located in the same directory (i.e. it will overwrite
      the source file).

     -Typing PKLITE on the command line with no options, will bring up
      a help screen listing all the program options.


      CAUTION

          It is very important that you do not use PKLITE on original
          program diskettes.  You should always make a copy of the
          original diskettes that are supplied with an application,
          and work only from the copies.  All original diskettes
          should be kept in safe place.
