-
-                Frequently Asked Questions about zlib
-
-
-If your question is not there, please check the zlib home page
-http://zlib.net/ which may have more recent information.
-The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
-
-
- 1. Is zlib Y2K-compliant?
-
-    Yes. zlib doesn't handle dates.
-
- 2. Where can I get a Windows DLL version?
-
-    The zlib sources can be compiled without change to produce a DLL.  See the
-    file win32/DLL_FAQ.txt in the zlib distribution.  Pointers to the
-    precompiled DLL are found in the zlib web site at http://zlib.net/ .
-
- 3. Where can I get a Visual Basic interface to zlib?
-
-    See
-        * http://marknelson.us/1997/01/01/zlib-engine/
-        * win32/DLL_FAQ.txt in the zlib distribution
-
- 4. compress() returns Z_BUF_ERROR.
-
-    Make sure that before the call of compress(), the length of the compressed
-    buffer is equal to the available size of the compressed buffer and not
-    zero.  For Visual Basic, check that this parameter is passed by reference
-    ("as any"), not by value ("as long").
-
- 5. deflate() or inflate() returns Z_BUF_ERROR.
-
-    Before making the call, make sure that avail_in and avail_out are not zero.
-    When setting the parameter flush equal to Z_FINISH, also make sure that
-    avail_out is big enough to allow processing all pending input.  Note that a
-    Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
-    made with more input or output space.  A Z_BUF_ERROR may in fact be
-    unavoidable depending on how the functions are used, since it is not
-    possible to tell whether or not there is more output pending when
-    strm.avail_out returns with zero.  See http://zlib.net/zlib_how.html for a
-    heavily annotated example.
-
- 6. Where's the zlib documentation (man pages, etc.)?
-
-    It's in zlib.h .  Examples of zlib usage are in the files test/example.c
-    and test/minigzip.c, with more in examples/ .
-
- 7. Why don't you use GNU autoconf or libtool or ...?
-
-    Because we would like to keep zlib as a very small and simple package.
-    zlib is rather portable and doesn't need much configuration.
-
- 8. I found a bug in zlib.
-
-    Most of the time, such problems are due to an incorrect usage of zlib.
-    Please try to reproduce the problem with a small program and send the
-    corresponding source to us at zlib@gzip.org .  Do not send multi-megabyte
-    data files without prior agreement.
-
- 9. Why do I get "undefined reference to gzputc"?
-
-    If "make test" produces something like
-
-       example.o(.text+0x154): undefined reference to `gzputc'
-
-    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
-    /usr/X11R6/lib. Remove any old versions, then do "make install".
-
-10. I need a Delphi interface to zlib.
-
-    See the contrib/delphi directory in the zlib distribution.
-
-11. Can zlib handle .zip archives?
-
-    Not by itself, no.  See the directory contrib/minizip in the zlib
-    distribution.
-
-12. Can zlib handle .Z files?
-
-    No, sorry.  You have to spawn an uncompress or gunzip subprocess, or adapt
-    the code of uncompress on your own.
-
-13. How can I make a Unix shared library?
-
-    By default a shared (and a static) library is built for Unix.  So:
-
-    make distclean
-    ./configure
-    make
-
-14. How do I install a shared zlib library on Unix?
-
-    After the above, then:
-
-    make install
-
-    However, many flavors of Unix come with a shared zlib already installed.
-    Before going to the trouble of compiling a shared version of zlib and
-    trying to install it, you may want to check if it's already there!  If you
-    can #include <zlib.h>, it's there.  The -lz option will probably link to
-    it.  You can check the version at the top of zlib.h or with the
-    ZLIB_VERSION symbol defined in zlib.h .
-
-15. I have a question about OttoPDF.
-
-    We are not the authors of OttoPDF. The real author is on the OttoPDF web
-    site: Joel Hainley, jhainley@myndkryme.com.
-
-16. Can zlib decode Flate data in an Adobe PDF file?
-
-    Yes. See http://www.pdflib.com/ . To modify PDF forms, see
-    http://sourceforge.net/projects/acroformtool/ .
-
-17. Why am I getting this "register_frame_info not found" error on Solaris?
-
-    After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
-    generates an error such as:
-
-        ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
-        symbol __register_frame_info: referenced symbol not found
-
-    The symbol __register_frame_info is not part of zlib, it is generated by
-    the C compiler (cc or gcc).  You must recompile applications using zlib
-    which have this problem.  This problem is specific to Solaris.  See
-    http://www.sunfreeware.com for Solaris versions of zlib and applications
-    using zlib.
-
-18. Why does gzip give an error on a file I make with compress/deflate?
-
-    The compress and deflate functions produce data in the zlib format, which
-    is different and incompatible with the gzip format.  The gz* functions in
-    zlib on the other hand use the gzip format.  Both the zlib and gzip formats
-    use the same compressed data format internally, but have different headers
-    and trailers around the compressed data.
-
-19. Ok, so why are there two different formats?
-
-    The gzip format was designed to retain the directory information about a
-    single file, such as the name and last modification date.  The zlib format
-    on the other hand was designed for in-memory and communication channel
-    applications, and has a much more compact header and trailer and uses a
-    faster integrity check than gzip.
-
-20. Well that's nice, but how do I make a gzip file in memory?
-
-    You can request that deflate write the gzip format instead of the zlib
-    format using deflateInit2().  You can also request that inflate decode the
-    gzip format using inflateInit2().  Read zlib.h for more details.
-
-21. Is zlib thread-safe?
-
-    Yes.  However any library routines that zlib uses and any application-
-    provided memory allocation routines must also be thread-safe.  zlib's gz*
-    functions use stdio library routines, and most of zlib's functions use the
-    library memory allocation routines by default.  zlib's *Init* functions
-    allow for the application to provide custom memory allocation routines.
-
-    Of course, you should only operate on any given zlib or gzip stream from a
-    single thread at a time.
-
-22. Can I use zlib in my commercial application?
-
-    Yes.  Please read the license in zlib.h.
-
-23. Is zlib under the GNU license?
-
-    No.  Please read the license in zlib.h.
-
-24. The license says that altered source versions must be "plainly marked". So
-    what exactly do I need to do to meet that requirement?
-
-    You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h.  In
-    particular, the final version number needs to be changed to "f", and an
-    identification string should be appended to ZLIB_VERSION.  Version numbers
-    x.x.x.f are reserved for modifications to zlib by others than the zlib
-    maintainers.  For example, if the version of the base zlib you are altering
-    is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
-    ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3".  You can also
-    update the version strings in deflate.c and inftrees.c.
-
-    For altered source distributions, you should also note the origin and
-    nature of the changes in zlib.h, as well as in ChangeLog and README, along
-    with the dates of the alterations.  The origin should include at least your
-    name (or your company's name), and an email address to contact for help or
-    issues with the library.
-
-    Note that distributing a compiled zlib library along with zlib.h and
-    zconf.h is also a source distribution, and so you should change
-    ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
-    in zlib.h as you would for a full source distribution.
-
-25. Will zlib work on a big-endian or little-endian architecture, and can I
-    exchange compressed data between them?
-
-    Yes and yes.
-
-26. Will zlib work on a 64-bit machine?
-
-    Yes.  It has been tested on 64-bit machines, and has no dependence on any
-    data types being limited to 32-bits in length.  If you have any
-    difficulties, please provide a complete problem report to zlib@gzip.org
-
-27. Will zlib decompress data from the PKWare Data Compression Library?
-
-    No.  The PKWare DCL uses a completely different compressed data format than
-    does PKZIP and zlib.  However, you can look in zlib's contrib/blast
-    directory for a possible solution to your problem.
-
-28. Can I access data randomly in a compressed stream?
-
-    No, not without some preparation.  If when compressing you periodically use
-    Z_FULL_FLUSH, carefully write all the pending data at those points, and
-    keep an index of those locations, then you can start decompression at those
-    points.  You have to be careful to not use Z_FULL_FLUSH too often, since it
-    can significantly degrade compression.  Alternatively, you can scan a
-    deflate stream once to generate an index, and then use that index for
-    random access.  See examples/zran.c .
-
-29. Does zlib work on MVS, OS/390, CICS, etc.?
-
-    It has in the past, but we have not heard of any recent evidence.  There
-    were working ports of zlib 1.1.4 to MVS, but those links no longer work.
-    If you know of recent, successful applications of zlib on these operating
-    systems, please let us know.  Thanks.
-
-30. Is there some simpler, easier to read version of inflate I can look at to
-    understand the deflate format?
-
-    First off, you should read RFC 1951.  Second, yes.  Look in zlib's
-    contrib/puff directory.
-
-31. Does zlib infringe on any patents?
-
-    As far as we know, no.  In fact, that was originally the whole point behind
-    zlib.  Look here for some more information:
-
-    http://www.gzip.org/#faq11
-
-32. Can zlib work with greater than 4 GB of data?
-
-    Yes.  inflate() and deflate() will process any amount of data correctly.
-    Each call of inflate() or deflate() is limited to input and output chunks
-    of the maximum value that can be stored in the compiler's "unsigned int"
-    type, but there is no limit to the number of chunks.  Note however that the
-    strm.total_in and strm_total_out counters may be limited to 4 GB.  These
-    counters are provided as a convenience and are not used internally by
-    inflate() or deflate().  The application can easily set up its own counters
-    updated after each call of inflate() or deflate() to count beyond 4 GB.
-    compress() and uncompress() may be limited to 4 GB, since they operate in a
-    single call.  gzseek() and gztell() may be limited to 4 GB depending on how
-    zlib is compiled.  See the zlibCompileFlags() function in zlib.h.
-
-    The word "may" appears several times above since there is a 4 GB limit only
-    if the compiler's "long" type is 32 bits.  If the compiler's "long" type is
-    64 bits, then the limit is 16 exabytes.
-
-33. Does zlib have any security vulnerabilities?
-
-    The only one that we are aware of is potentially in gzprintf().  If zlib is
-    compiled to use sprintf() or vsprintf(), then there is no protection
-    against a buffer overflow of an 8K string space (or other value as set by
-    gzbuffer()), other than the caller of gzprintf() assuring that the output
-    will not exceed 8K.  On the other hand, if zlib is compiled to use
-    snprintf() or vsnprintf(), which should normally be the case, then there is
-    no vulnerability.  The ./configure script will display warnings if an
-    insecure variation of sprintf() will be used by gzprintf().  Also the
-    zlibCompileFlags() function will return information on what variant of
-    sprintf() is used by gzprintf().
-
-    If you don't have snprintf() or vsnprintf() and would like one, you can
-    find a portable implementation here:
-
-        http://www.ijs.si/software/snprintf/
-
-    Note that you should be using the most recent version of zlib.  Versions
-    1.1.3 and before were subject to a double-free vulnerability, and versions
-    1.2.1 and 1.2.2 were subject to an access exception when decompressing
-    invalid compressed data.
-
-34. Is there a Java version of zlib?
-
-    Probably what you want is to use zlib in Java. zlib is already included
-    as part of the Java SDK in the java.util.zip package. If you really want
-    a version of zlib written in the Java language, look on the zlib home
-    page for links: http://zlib.net/ .
-
-35. I get this or that compiler or source-code scanner warning when I crank it
-    up to maximally-pedantic. Can't you guys write proper code?
-
-    Many years ago, we gave up attempting to avoid warnings on every compiler
-    in the universe.  It just got to be a waste of time, and some compilers
-    were downright silly as well as contradicted each other.  So now, we simply
-    make sure that the code always works.
-
-36. Valgrind (or some similar memory access checker) says that deflate is
-    performing a conditional jump that depends on an uninitialized value.
-    Isn't that a bug?
-
-    No.  That is intentional for performance reasons, and the output of deflate
-    is not affected.  This only started showing up recently since zlib 1.2.x
-    uses malloc() by default for allocations, whereas earlier versions used
-    calloc(), which zeros out the allocated memory.  Even though the code was
-    correct, versions 1.2.4 and later was changed to not stimulate these
-    checkers.
-
-37. Will zlib read the (insert any ancient or arcane format here) compressed
-    data format?
-
-    Probably not. Look in the comp.compression FAQ for pointers to various
-    formats and associated software.
-
-38. How can I encrypt/decrypt zip files with zlib?
-
-    zlib doesn't support encryption.  The original PKZIP encryption is very
-    weak and can be broken with freely available programs.  To get strong
-    encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
-    compression.  For PKZIP compatible "encryption", look at
-    http://www.info-zip.org/
-
-39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
-
-    "gzip" is the gzip format, and "deflate" is the zlib format.  They should
-    probably have called the second one "zlib" instead to avoid confusion with
-    the raw deflate compressed data format.  While the HTTP 1.1 RFC 2616
-    correctly points to the zlib specification in RFC 1950 for the "deflate"
-    transfer encoding, there have been reports of servers and browsers that
-    incorrectly produce or expect raw deflate data per the deflate
-    specification in RFC 1951, most notably Microsoft.  So even though the
-    "deflate" transfer encoding using the zlib format would be the more
-    efficient approach (and in fact exactly what the zlib format was designed
-    for), using the "gzip" transfer encoding is probably more reliable due to
-    an unfortunate choice of name on the part of the HTTP 1.1 authors.
-
-    Bottom line: use the gzip format for HTTP 1.1 encoding.
-
-40. Does zlib support the new "Deflate64" format introduced by PKWare?
-
-    No.  PKWare has apparently decided to keep that format proprietary, since
-    they have not documented it as they have previous compression formats.  In
-    any case, the compression improvements are so modest compared to other more
-    modern approaches, that it's not worth the effort to implement.
-
-41. I'm having a problem with the zip functions in zlib, can you help?
-
-    There are no zip functions in zlib.  You are probably using minizip by
-    Giles Vollant, which is found in the contrib directory of zlib.  It is not
-    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The
-    files in there are not supported by the zlib authors.  You need to contact
-    the authors of the respective contribution for help.
-
-42. The match.asm code in contrib is under the GNU General Public License.
-    Since it's part of zlib, doesn't that mean that all of zlib falls under the
-    GNU GPL?
-
-    No.  The files in contrib are not part of zlib.  They were contributed by
-    other authors and are provided as a convenience to the user within the zlib
-    distribution.  Each item in contrib has its own license.
-
-43. Is zlib subject to export controls?  What is its ECCN?
-
-    zlib is not subject to export controls, and so is classified as EAR99.
-
-44. Can you please sign these lengthy legal documents and fax them back to us
-    so that we can use your software in our product?
-
-    No. Go away. Shoo.

-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.11 is a general purpose data compression library.  All the code is
-thread safe.  The data format used by the zlib library is described by RFCs
-(Request for Comments) 1950 to 1952 in the files
-http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
-rfc1952 (gzip format).
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact zlib@gzip.org).  A usage example
-of the library is given in the file test/example.c which also tests that
-the library is working correctly.  Another example is given in the file
-test/minigzip.c.  The compression library itself is composed of all source
-files in the root directory.
-
-To compile all files and run the test program, follow the instructions given at
-the top of Makefile.in.  In short "./configure; make test", and if that goes
-well, "make install" should work for most flavors of Unix.  For Windows, use
-one of the special makefiles in win32/ or contrib/vstudio/ .  For VMS, use
-make_vms.com.
-
-Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
-<info@winimage.com> for the Windows DLL version.  The zlib home page is
-http://zlib.net/ .  Before reporting a problem, please check this site to
-verify that you have the latest version of zlib; otherwise get the latest
-version and check whether the problem still exists or not.
-
-PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
-
-Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan.  1997
-issue of Dr.  Dobb's Journal; a copy of the article is available at
-http://marknelson.us/1997/01/01/zlib-engine/ .
-
-The changes made in version 1.2.11 are documented in the file ChangeLog.
-
-Unsupported third party contributions are provided in directory contrib/ .
-
-zlib is available in Java using the java.util.zip package, documented at
-http://java.sun.com/developer/technicalArticles/Programming/compression/ .
-
-A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
-at CPAN (Comprehensive Perl Archive Network) sites, including
-http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
-
-A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
-available in Python 1.5 and later versions, see
-http://docs.python.org/library/zlib.html .
-
-zlib is built into tcl: http://wiki.tcl.tk/4610 .
-
-An experimental package to read and write files in .zip format, written on top
-of zlib by Gilles Vollant <info@winimage.com>, is available in the
-contrib/minizip directory of zlib.
-
-
-Notes for some targets:
-
-- For Windows DLL versions, please see win32/DLL_FAQ.txt
-
-- For 64-bit Irix, deflate.c must be compiled without any optimization. With
-  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
-  compiler flag). The compiler bug has been reported to SGI.
-
-- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
-  when compiled with cc.
-
-- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
-  necessary to get gzprintf working correctly. This is done by configure.
-
-- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
-  other compilers. Use "make test" to check your compiler.
-
-- gzdopen is not supported on RISCOS or BEOS.
-
-- For PalmOs, see http://palmzlib.sourceforge.net/
-

-Acknowledgments:
-
-  The deflate format used by zlib was defined by Phil Katz.  The deflate and
-  zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
-  people who reported problems and suggested various improvements in zlib; they
-  are too numerous to cite here.

-                        Release 1.3
-
-ZLib.Ada is a thick binding interface to the popular ZLib data
-compression library, available at http://www.gzip.org/zlib/.
-It provides Ada-style access to the ZLib C library.
-
-
-        Here are the main changes since ZLib.Ada 1.2:
-
-- Attension: ZLib.Read generic routine have a initialization requirement
-  for Read_Last parameter now. It is a bit incompartible with previous version,
-  but extends functionality, we could use new parameters Allow_Read_Some and
-  Flush now.
-
-- Added Is_Open routines to ZLib and ZLib.Streams packages.
-
-- Add pragma Assert to check Stream_Element is 8 bit.
-
-- Fix extraction to buffer with exact known decompressed size. Error reported by
-  Steve Sangwine.
-
-- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
-  computers. Patch provided by Pascal Obry.
-
-- Add Status_Error exception definition.
-
-- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
-
-
-        How to build ZLib.Ada under GNAT
-
-You should have the ZLib library already build on your computer, before
-building ZLib.Ada. Make the directory of ZLib.Ada sources current and
-issue the command:
-
-  gnatmake test -largs -L<directory where libz.a is> -lz
-
-Or use the GNAT project file build for GNAT 3.15 or later:
-
-  gnatmake -Pzlib.gpr -L<directory where libz.a is>
-
-
-        How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
-
-1. Make a project with all *.ads and *.adb files from the distribution.
-2. Build the libz.a library from the ZLib C sources.
-3. Rename libz.a to z.lib.
-4. Add the library z.lib to the project.
-5. Add the libc.lib library from the ObjectAda distribution to the project.
-6. Build the executable using test.adb as a main procedure.
-
-
-        How to use ZLib.Ada
-
-The source files test.adb and read.adb are small demo programs that show
-the main functionality of ZLib.Ada.
-
-The routines from the package specifications are commented.

-This is a patched version of zlib, modified to use
-Pentium-Pro-optimized assembly code in the deflation algorithm. The
-files changed/added by this patch are:
-
-README.686
-match.S
-
-The speedup that this patch provides varies, depending on whether the
-compiler used to build the original version of zlib falls afoul of the
-PPro's speed traps. My own tests show a speedup of around 10-20% at
-the default compression level, and 20-30% using -9, against a version
-compiled using gcc 2.7.2.3. Your mileage may vary.
-
-Note that this code has been tailored for the PPro/PII in particular,
-and will not perform particuarly well on a Pentium.
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)

-
-Added for zlib 1.1.3:
-
-The patches come from
-http://www.muppetlabs.com/~breadbox/software/assembly.html
-
-To compile zlib with this asm file, copy match.S to the zlib directory
-then do:
-
-CFLAGS="-O3 -DASMV" ./configure
-make OBJA=match.o
-
-
-Update:
-
-I've been ignoring these assembly routines for years, believing that
-gcc's generated code had caught up with it sometime around gcc 2.95
-and the major rearchitecting of the Pentium 4. However, I recently
-learned that, despite what I believed, this code still has some life
-in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
-faster than the code produced by gcc 4.1.
-
-In acknowledgement of its continuing usefulness, I've altered the
-license to match that of the rest of zlib. Share and Enjoy!

- * Decode PKWare Compression Library stream.

- * Format notes:
- *
- * - First byte is 0 if literals are uncoded or 1 if they are coded.  Second
- *   byte is 4, 5, or 6 for the number of extra bits in the distance code.
- *   This is the base-2 logarithm of the dictionary size minus six.
- *
- * - Compressed data is a combination of literals and length/distance pairs
- *   terminated by an end code.  Literals are either Huffman coded or
- *   uncoded bytes.  A length/distance pair is a coded length followed by a
- *   coded distance to represent a string that occurs earlier in the
- *   uncompressed data that occurs again at the current location.
- *
- * - A bit preceding a literal or length/distance pair indicates which comes
- *   next, 0 for literals, 1 for length/distance.
- *
- * - If literals are uncoded, then the next eight bits are the literal, in the
- *   normal bit order in the stream, i.e. no bit-reversal is needed. Similarly,
- *   no bit reversal is needed for either the length extra bits or the distance
- *   extra bits.
- *
- * - Literal bytes are simply written to the output.  A length/distance pair is
- *   an instruction to copy previously uncompressed bytes to the output.  The
- *   copy is from distance bytes back in the output stream, copying for length
- *   bytes.
- *
- * - Distances pointing before the beginning of the output data are not
- *   permitted.
- *
- * - Overlapped copies, where the length is greater than the distance, are
- *   allowed and common.  For example, a distance of one and a length of 518
- *   simply copies the last byte 518 times.  A distance of four and a length of
- *   twelve copies the last four bytes three times.  A simple forward copy
- *   ignoring whether the length is greater than the distance or not implements
- *   this correctly.

-Overview
-========
-
-This directory contains an update to the ZLib interface unit,
-distributed by Borland as a Delphi supplemental component.
-
-The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
-and is based on zlib version 1.0.4.  There are a series of bugs
-and security problems associated with that old zlib version, and
-we recommend the users to update their ZLib unit.
-
-
-Summary of modifications
-========================
-
-- Improved makefile, adapted to zlib version 1.2.1.
-
-- Some field types from TZStreamRec are changed from Integer to
-  Longint, for consistency with the zlib.h header, and for 64-bit
-  readiness.
-
-- The zlib_version constant is updated.
-
-- The new Z_RLE strategy has its corresponding symbolic constant.
-
-- The allocation and deallocation functions and function types
-  (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
-  and _malloc and _free are added as C RTL stubs.  As a result,
-  the original C sources of zlib can be compiled out of the box,
-  and linked to the ZLib unit.
-
-
-Suggestions for improvements
-============================
-
-Currently, the ZLib unit provides only a limited wrapper around
-the zlib library, and much of the original zlib functionality is
-missing.  Handling compressed file formats like ZIP/GZIP or PNG
-cannot be implemented without having this functionality.
-Applications that handle these formats are either using their own,
-duplicated code, or not using the ZLib unit at all.
-
-Here are a few suggestions:
-
-- Checksum class wrappers around adler32() and crc32(), similar
-  to the Java classes that implement the java.util.zip.Checksum
-  interface.
-
-- The ability to read and write raw deflate streams, without the
-  zlib stream header and trailer.  Raw deflate streams are used
-  in the ZIP file format.
-
-- The ability to read and write gzip streams, used in the GZIP
-  file format, and normally produced by the gzip program.
-
-- The ability to select a different compression strategy, useful
-  to PNG and MNG image compression, and to multimedia compression
-  in general.  Besides the compression level
-
-    TCompressionLevel = (clNone, clFastest, clDefault, clMax);
-
-  which, in fact, could have used the 'z' prefix and avoided
-  TColor-like symbols
-
-    TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
-
-  there could be a compression strategy
-
-    TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
-
-- ZIP and GZIP stream handling via TStreams.
