-----------
PLEASE NOTE
-----------

This LSP-Shell Demo is **NOT** the LSPack for CW (LSP) toolkit. It
is **only** a simple sample application (front-end) to demonstrate
the power of the LSP toolkit (back-end). LSPack for CW is a toolkit
for Clarion developers who want to use compression and decompression
functions from within their applications without having to "shell"
to a DOS session.

====================================================================
                    Compression the right way
====================================================================

LSPack for CW (LSP) is a comprehensive library of functions that
allows you to incorporate sophisticated compression technology into
your Clarion for Windows application. Using the robust LSP "API"
("Application Programmer's Interface"), you can write software to
perform simple data in, data out compression as well as create
multi-file archives supporting features normally associated with
stand-alone utilities like PKZIP, ZOO, LHARC or others.

By using LSP, you'll never have to shell out to the operation system
again. You don't have to learn hundreds of calls or countless
parameters. Only a few functions give you total control where you
need it, simplicity where you want it.  LSP differs from competitors
by providing more than simple data in / data out compression. In
addition to such functions, LSP also provides advanced support for
multi-file archives, 32-bit CRC computations, file and directory
management functions, text vs. binary data recognition, adjustable
temp-files, automatic Long File Name to Short File Name conversion
(under 'Down Level Systems'), service functions (GetFreeDisk(),
FileExists()) royalty-free DLLs and much more...

To aid in learning to use LSP, a full featured Windows LSP Shell
program is provided with full Clarion source code, along with five
sample applications and a Windows Help File system.

====================================================================
                      Get lots of flexibility
====================================================================

The LSP Toolkit is chock full of properties and methods which give
you plenty of flexibility when you're building your Clarion
application. Over 10 properties can be set at design or runtime. Set
the LSP_USE_TEMP_PATH to True and during the compression process the
pathname will be stored along with the filename. Set the
LSP_USE_TEMP_PATH to False during the decompression process the path
will not be reconstructed.

LSP is available in both 16 and 32 bit versions, for Windows 3.1x,
Windows 95 and Windows NT. Just add the LSP library to your project,
set a few parameters and you'll be PACKing and UnPACKing in minutes!
You can literally copy code from the online help or the sample
applications right into your project and create a LSP archive without
writing a single line of code !

We have already formed the foundation to support the industry ZIP
standard.

====================================================================
              A few LSP-Shell function descriptions
====================================================================

The following functions are native LSP-toolkit (back-end) functions
and are NOT provided through the LSP-Shell. You are able to use such
a function directly from within your Clarion application.

- Suppress Item Exist Check (LSPACK)

  You should NOT use this option when adding files to an existing
  backup type archive because LSP will not check for dublicate
  files. You could end up with duplicate files in the archive as
  opposed to one recent file and several backup files.

  This function enables you to make HIGH-SPEED-DIRECTORY backups.

- Backup-Mode (LSPACK)

  Only a not already existing file will be added to the archive
  during the (directory) backup process.

- Quiet Mode (LSPACK/LSUNPACK)

  Indicates wether to suppress most informational and warning
  message boxes displayed by the DLL.

- Create Directory

  This function will create a directory (if not already exists)
  without prompting to the user.

- Use Original Path Info

  This function enables to unPACK an item from the archive to the
  full paths in the current directory or to the base directory if
  specified. LSP normally stores pathnames as if they were children
  of the target directory.
