>LS_Pack INFO
>============
>LS_Pack was planed to support compression/decompression functions
>from within CW. Because LS_Pack is not my "main-product" I cannot
>go into competition with the PKZIP(R) method.
>
>At the moment the LS_Pack system contains two compression algorithms:
>
>(1) FAST - maximal compression speed
>(2) EXTRA - maximal compression ratio
>
>The "EXTRA" compression ratio is much more better than the LZW
>algorithm but it is about + 2-5% of pkzips deflate method. The problem
>is the compression time (the de-compression time is always fine).
>The PKZIP method (for Windows - P5-120 - 32MB) needs about 40 seconds
>to compress all files of the Calgary/Canterbury compression corpus.
>The "EXTRA" algorithm of LS_Pack needs about 135 seconds! The "FAST"
>algorithm is faster than PKZIP but the compression ratio is about +40 %
>of the "EXTRA" mode.
>
>I am still working on an algorithm to handle the optimal SIZE/TIME
>combination automatically. For example if you compress the files
>BOOK1 (750K) and PIC (501K) using the "FAST" mode instead of the
>"EXTRA" mode, the compression time is about 59 !!! seconds faster but
>the archive size is about 160K larger.

>
>During the last four days I received several e-mails containing
>similar questions. This is a list of some "Frequently Asked
>Questions".
>
>1. Why not make a public Beta of LS_Pack for CW?
>
> -- LS_Pack for CW **is** a public beta. You only have to send an
> e-mail and you are on my list.
>
>2. For what reason are the LS_Pack files in Library 11 and on your
> WWW-Site password protected?
>
> -- I want to know who is still working with LS_Pack for CW.
> This is very important because if there were critical errors
> found I will inform the Beta tester.
>
>3. I'd like to Beta LS-Pack. How will I pay?
>
> -- The LS_Pack Beta is **FREE OF CHARGE**. Please do **NOT**
> send a check or your credit card number <g>.
>
>4. Are there versions for LS_Pack 16 and 32 bit?
>
> -- At the moment the LS_Pack toolkit is still under construction
> and is available for 16-bit only. The 32-bit version will be
> my #1 priority after the 16-bit version works solid.
>
>5. Is it possible to ship the LS_Pack 1.0 for CW DLLs to my
> customers?
>
> -- Yes, of course. After registering the full featured LS_Pack
> 1.0 for CW (not the Beta versions) with Linder Software
> Systems, distribute the DLLs royalty free AS PART OF ONE OR
> MORE END-USER APPLICATIONS WITH THE FOLLOWING RESTRICTIONS:
>
> a.) YOU MAY NOT PROVIDE THEM AS PART OF A DEVELOPER'S
> COMPRESSION / DECOMPRESSION TOOLKIT
>
> -and-
>
> b.) YOU MAY NOT DISTRIBUTE INFORMATION ABOUT THE API,
> STRUCTURES, OR RETURN CODES INHERENT IN THE LS_Pack DLLs.
>
>6. Can I create self-extracting archives (and do I have to pay
> royalties if distributing these files)?
>
> -- The Beta-1 of LS_Pack cannot create self-extracting archives
> (although the LS_SFX code is ready to run) because this will
> not be a standard version feature. Some developer do not
> need this function and why pay for something that will never
> be used? I think the LS_SFX add-on will cost US$15.
>
> -- You do not need a "Distributing License" to ship LS_SFX files.
>
>7. What are the sizes of the DLLs? The LS_Pack toolkit is not of
> interest if the decompression DLL size is over 80K !
>
> -- At the moment the decompression library is only about 25K and
> the compression library is about 30K.
>
>8. Do you make plans to upload a non-password protected demo of your
> product?
>
> -- I am thinking about publishing a LS_Pack Shell demo. Have a
> look to Library 11 within the next 10 or 12 days.
>
>9. Is it possible to use LS_Pack in combination with say Delphi?
>
> -- LS_Pack was developed for Clarion for Windows Developer.
> Because LS_Pack is written entirely in C and is distributed as
> DLL it is generally possible to use it with any language that
> can call DLLs.

>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 six sample applications
>and a Windows Help File system.

>The LSP Toolkit is chock full of properties and methods which give you plenty

>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.
>The LSP v1.0 system already includes (and uses) the compression / decompression
