+        ZLIB version 1.2.0.7 for AS400 installation instructions
+
+I) From an AS400 *SAVF file:
+
+1)      Unpacking archive to an AS400 save file
+
+On the AS400:
+
+_       Create the ZLIB AS400 library:
+
+        CRTLIB LIB(ZLIB) TYPE(PROD) TEXT('ZLIB compression API library')
+
+_       Create a work save file, for example:
+
+                CRTSAVF FILE(ZLIB/ZLIBSAVF)
+
+On a PC connected to the target AS400:
+
+_       Unpack the save file image to a PC file "ZLIBSAVF"
+_       Upload this file into the save file on the AS400, for example
+                using ftp in BINARY mode.
+
+
+2)      Populating the ZLIB AS400 source library
+
+On the AS400:
+
+_       Extract the saved objects into the ZLIB AS400 library using:
+
+RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
+
+
+3)      Customize installation:
+
+_       Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
+                according to the comments.
+
+_       Compile this member with:
+
+        CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
+
+
+4)      Compile and generate the service program:
+
+_       This can now be done by executing:
+
+        CALL PGM(ZLIB/COMPILE)
+
+
+
+II) From the original source distribution:
+
+1)      On the AS400, create the source library:
+
+        CRTLIB LIB(ZLIB) TYPE(PROD) TEXT('ZLIB compression API library')
+
+2)      Create the source files:
+
+        CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
+        CRTSRCPF FILE(ZLIB/H)       RCDLEN(112) TEXT('ZLIB library includes')
+        CRTSRCPF FILE(ZLIB/TOOLS)   RCDLEN(112) TEXT('ZLIB library control utilities')
+
+3)      From the machine hosting the distribution files, upload them (with
+                FTP in text mode, for example) according to the following table:

+Notes:  For AS400 ILE RPG programmers, a /copy member defining the ZLIB
+                API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
+                Please read comments in this member for more information.
+
+        Remember that most foreign textual data are ASCII coded: this
+                implementation does not handle conversion from/to ASCII, so
+                text data code conversions must be done explicitely.
+
+        Always open zipped files in binary mode.

+			ZLib for Ada thick binding (ZLib.Ada)
+			Release 1.2
+
+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 1.1:
+
+- The default header type has a name "Default" now. Auto is used only for
+  automatic GZip/ZLib header detection.
+
+- Added test for multitasking mtest.adb.
+
+- Added GNAT project file zlib.gpr.
+
+
+	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.

+
+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 1.2.0.
+
+- 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.

+/*
+   gzappend takes a gzip file and appends to it, compressing files from the
+   command line or data from stdin.  The gzip file is written to directly, to
+   avoid copying that file, in case it's large.  Note that this results in the
+   unfriendly behavior that if gzappend fails, the gzip file is corrupted.
+
+   This program was written to illustrate the use of the new Z_BLOCK option of
+   zlib 1.2.1's inflate() function.  This option returns from inflate() at each
+   block boundary to facilitate locating and modifying the last block bit at
+   the start of the final deflate block.  Also whether using Z_BLOCK or not,
+   another required feature of zlib 1.2.1 is that inflate() now provides the
+   number of unusued bits in the last input byte used.  gzappend will not work
+   with versions of zlib earlier than 1.2.1.
+
+   gzappend first decompresses the gzip file internally, discarding all but
+   the last 32K of uncompressed data, and noting the location of the last block
+   bit and the number of unused bits in the last byte of the compressed data.
+   The gzip trailer containing the CRC-32 and length of the uncompressed data
+   is verified.  This trailer will be later overwritten.
+
+   Then the last block bit is cleared by seeking back in the file and rewriting
+   the byte that contains it.  Seeking forward, the last byte of the compressed
+   data is saved along with the number of unused bits to initialize deflate.
+
+   A deflate process is initialized, using the last 32K of the uncompressed
+   data from the gzip file to initialize the dictionary.  If the total
+   uncompressed data was less than 32K, then all of it is used to initialize

+   strm provides the memory allocation functions and window buffer on input,
+   and provides information on the unused input on return.  For Z_DATA_ERROR
+   returns, strm will also provide an error message.
+
+   in() and out() are the call-back input and output functions.  When
+   inflateBack() needs more input, it calls in().  When inflateBack() has
+   filled the window with output, or when it completes with data in the
+   window, it calls out() to write out the data.  The application must not
+   change the provided input until in() is called again or inflateBack()
+   returns.  The application must not change the window/output buffer until
+   inflateBack() returns.
+
+   in() and out() are called with a descriptor parameter provided in the
+   inflateBack() call.  This parameter can be a structure that provides the
+   information required to do the read or write, as well as accumulated
+   information on the input and output such as totals and check values.
+
+   in() should return zero on failure.  out() should return non-zero on
+   failure.  If either in() or out() fails, than inflateBack() returns a
+   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
+   was in() or out() that caused in the error.  Otherwise,  inflateBack()
+   returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+   error, or Z_MEM_ERROR if it could not allocate memory for the state.
+   inflateBack() can also return Z_STREAM_ERROR if the input parameters
+   are not correct, i.e. strm is Z_NULL or the state was not initialized.

+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+example.pas     usage example of zlib
+zlibpas.pas     the Pascal interface to zlib
+readme.txt      this file
+
+
+Compatibility notes
+===================
+
+- Although the name "zlib" would have been more normal for the
+  zlibpas unit, this name is already taken by Borland's ZLib unit.
+  This is somehow unfortunate, because that unit is not a genuine
+  interface to the full-fledged zlib functionality, but a suite of
+  class wrappers around zlib streams.  Other essential features,
+  such as checksums, are missing.
+  It would have been more appropriate for that unit to have a name
+  like "ZStreams", or something similar.
+
+- The C and zlib-supplied types int, uInt, long, uLong, etc. are
+  translated directly into Pascal types of similar sizes (Integer,
+  LongInt, etc.), to avoid namespace pollution.  In particular,
+  there is no conversion of unsigned int into a Pascal unsigned
+  integer.  The Word type is non-portable and has the same size
+  (16 bits) both in a 16-bit and in a 32-bit environment, unlike
+  Integer.  Even if there is a 32-bit Cardinal type, there is no
+  real need for unsigned int in zlib under a 32-bit environment.
+
+- Except for the callbacks, the zlib function interfaces are
+  assuming the calling convention normally used in Pascal
+  (__pascal for DOS and Windows16, __fastcall for Windows32).
+  Since the cdecl keyword is used, the old Turbo Pascal does
+  not work with this interface.
+
+- The gz* function interfaces are not translated, to avoid
+  interfacing problems with the C runtime library.  Besides,
+    gzprintf(gzFile file, const char *format, ...)
+  cannot be translated into Pascal.
