-The MetaKit Library 2.01                                            March 2000
-==============================================================================
-
-
-WHAT IT IS - MetaKit is an embeddable database which runs on Unix, Windows,
-    Macintosh, and other platforms.  It lets you build applications which
-    store their data efficiently, in a portable way, and which will not need a
-    complex runtime installation.  In terms of the data model, MetaKit takes
-    the middle ground between RDBMS, OODBMS, and flat-file databases - yet it
-    is quite different from each of them.
-
-WHAT IT ISN'T - MetaKit is not: 1) multi-user/-threading, 2) scalable to
-    gigabytes, 3) proprietary software, 4) full of bugs, 5) just a toy.
-
-TECHNOLOGY - Everything is stored variable-sized yet with efficient positional
-    row access.  Changing an existing datafile structure is as simple as re-
-    opening it with that new structure.  All changes are transacted.  You can
-    mix and match software written in C++, Python, and Tcl.  Things can't get
-    much more flexible...
-
-CORE - The Metakit core library is written in C++.  It has a code footprint of
-    just over 100 Kb on Windows.  It can be used as DLL, or linked statically.
-    Debug builds include extensive assertion checks to catch problems early.
-
-PYTHON - The binding for Python is called "Mk4py".  It uses SCXX by Gordon
-    McMillan as C++ glue interface.  The source is in directory "python/".
-
-TCL/TK - The MK extension for Tcl is called "Mk4tcl".  It is being used in a
-    number of commercial projects, for in-house use as well as in commercially
-    distributed products.  The source is in directory "tcl/".
-
-LICENSE AND SUPPORT - MetaKit 2.01 is distributed as open source software (the
-    X/MIT-style license is at the end of this document).  Commercial support
-    is available through an Enterprise License, see the URL mentioned below.
-
-DOCUMENTATION - All documentation uses HTML.  The main page is "MetaKit.html",
-    which leads to the rest of the documentation in the "doc/" directory.
-
-WEBSITE URLS - The main pages on the world wide web, for news and downloads:

-    Contact info:   http://www.equi4.com/contact.html
-
-
-INSTALLATION
-============
-
-Starting with this release, all platform builds and language bindings are now
-designed to work from a single common "builds/" directory.  It turns out to
-be impossible to keep build side-effects limited to *just* this directory
-(CodeWarrior can't be told where to place its temp data, and Visual C++ still
-alters a few files next to the project ".dsw" file, to name two offenders).
-
-UNIX
-
-    It is no longer advised to build the Unix code in the "unix/" directory.
-    Instead, you should perform the following steps:
-        % cd builds
-        % ../unix/configure
-        % make
-        % make test
-    And optionally (this only installs the core lib, not script extensions):
-        % make install
-
-    By switching to the "builds/" directory, you will keep the distribution
-    directory tree 100% unaltered.  All changes are made in this subdir, and
-    all final build results are left behind in this same subdir.
-
-    Nastiness: if you build Mk4tcl, please do a "make Mk4tcl.so" as well.
-    And if you intend to create the Python extension, do a "make Mk4py.so".
-    The "libmk4tcl.so.0.0.0" and "libMk4py.so.0.0.0" targets are bogus ones.
-
-    You will probably have to make changes in the makefile to locate the
-    proper includes and libs for Python (Tcl has been fixed, see "--with-tcl).
-    You probably only need to adjust "CXX_SWITCHES_PY" to find the headers.
-
-    To build with STL containers and strings, you can do the following:
-        make CXXFLAGS='-Dq4_STD' test   # add -O3 etc, as needed
-    This passes the test suite on Linux RedHat 5.2 with gcc 2.95-2.
-
-    See below for some platform-specific build notes.
-
-WINDOWS
-
-    There is a "win/" directory which contains subdirectories for a number of
-    compiler systems.  MetaKit has been built with many different compilers
-    in the past (Microsoft, Borland, Watcom, Symantec, Metrowerks, Optima),
-    but to preserve my sanity (there are 12 configurations for MSVC6 alone!),
-    I am limiting myself to MSVC6, MWCW5, Borland C++ Builder 4, and Cygwin.
-
-    The MS Visual C++ 6.0 project is "win/msvc60/mksrc.dsw", with subprojects
-    for the C++ demo (mkdemo), building dll's (mkdll), static libs (mklib),
-    regression tests (mktest), as well as Tcl (mktcl) and Python (mkpython).
-    It has been set up to place all intermediate files and final results in
-    the "builds/" subdirectory, even though you'll launch it from "win/".
-
-    To build with STL containers and strings under MSVC, define "q4_STD".
-    To build with MFC containers and strings under MSVC, define "q4_MFC".
-
-    The Metrowerks Codewarrior project is in the "mac/" directory, and can be
-    used to build both Mac and Windows versions (on either Mac *or* Windows).
-    The core libraries are built with "mac/cw5.mcp", demos / tests are built
-    with "cw5apps.mcp", Tcl is "cw5tcl.mcp", and Python is "cw5python.mcp".
-
-    The Borland C++ Builder projects have not yet been incorporated in this
-    release, but the "KitViewer" application is an example of how to use BCB.
-
-    The Cygwin build (B20.1 / gcc 2.95.2) is different, because it uses the
-    unix autoconf system, and must be launched as described above for UNIX.
-    I have upgraded to the latest development of libtool to be able to build
-    DLL's with Cygwin.  You can build the "-mno-cygwin" version by editing
-    the Makefile by hand and adding that option to CXXFLAGS.
-
-    Rob Bloodgood adds that the following GCC options are for maximum code
-    efficiency on x86 hardware: "-O2 -m486 -malign-loops=2 -malign-jumps=2".
-    I have not yet tried this myself, but am passing on the tip.
-
-MACINTOSH
-
-    The Mac version requires Metrowerks CodeWarrior 5.  See the info above
-    in the Windows section (MWCW is multi-platform).  The projects are all
-    located in the "mac/" folder, which is also where MWCW will place its own
-    "... Data" folders with intermediate results.  As with all other setups,
-    final results are made to end up in the "builds/" directory.
-
-    Static 68K builds appear to work fine, the 68K CFM variants will need
-    some more work (I couldn't get the libraries to export their symbols).
-
-
-PLATFORM-SPECIFIC NOTES
-=======================
-
-* Linux RH 5.2 / gcc 2.95.2
-
-    Builds with gcc 2.95.2 work out of the box.  The Tcl extension ends up as
-    ".libs/libmk4tcl.so.0.0.0" (to please libtool), and should be renamed to
-    "Mk4tcl.so".  Similarly, ".libs/libMk4py.so.0.0.0" is in fact the Python
-    extension, and *must* be renamed to "Mk4py.so" to call it from Python.
-
-    The core MK libs end up as ".libs/libmk4.a" and ".libs/libmk4.so.0.0.0".
-
-* Solaris 2.6 / gcc 2.8.1
-
-    The Solaris builds are nasty for several reasons:
-
-    - I do not own such a machine, and often have to make arrangements
-      (or fight limited space on one of the machines I can telnet to).
-    - The gcc 2.8.1 optimizer appears to be buggy, I have had to turn off
-      the default "-O3" flag to prevent compiler crashes (several files).
-      This problems appears to be resolved with gcc 2.95.
-    - Locking on Solaris (especially w.r.t NFS) remains a mystery to me.
-      The Tcl and Python extensions both use locking (the core not yet).
-      See tcl/Mk4tcl.cpp around line 520, and python/PyStorage.cpp around
-      line 80 for details.  It's all pretty messy, and not 100% correct.
-
-    Despite this, I'm doing my best to resolve these issues.  Having a solid
-    build of the core *and* of Tcl / Python extensions is quite important.
-
-* Other Unix systems
-
-    No further notes, though many systems will build fine out of the box.
-
-* Windows
-
-    MSVC 6 builds MK as static lib and as DLL (universal config, I have not
-    yet created build versions with MFC or STL, mainly because MK can now be
-    used in all contexts regardless of how it was built).  The Python and Tcl
-    extensions build as dynamic extensions (a static build is easy to add).
-
-    MWCW 5 builds MK as static lib and as DLL (interestingly enough, the DLL
-    is slightly smaller than MSVC 6 - 102 vs 108 Kb - when their runtimes are
-    linked in dynamically as well).  I have not added Win builds for Tcl or
-    Python, since MSVC 6 has those already.
-
-    Cygwin B20.1, with gcc 2.95.2 ugrade, also builds MK as static lib and as
-    DLL.  Both "pure" Cygwin (i.e. requiring cygwin1.dll) and mingw32 (using
-    the -mno-cygwin flag) build, but there are some hairy include issues when
-    it comes to choosing the right locking model for Tcl and Python.  These
-    issues have not been resolved fully.
-
-* Macintosh
-
-    MWCW 5 builds PPC shared libs, PPC static libs, and 68K static libraries.
-
-    Building 68K CFM libraries leads to a "MetaKit 68K.shlb" which comes out
-    of the linker without errors, but the result does not seem to have any
-    export symbols defined (despite the fact that the library is over 200 K).
-    Because of that, I've been unable to build apps or Mk4tcl/Mk4py so far.
-
-    The other three configurations build, but for some reason MK's regression
-    test stops at L03 (everything up to that point looks ok, i.e. over 90%).
-
-    The Mk4tcl PPC extension appears to work (quick manual test), and so does
-    the Python extension, "Mk4py.PPC.slb".  I have not yet given these two
-    a serious workout, hoping to have a basic test harness in place soon.
-
-* VMS, BeOS, ...
-
-    No news yet, please report your findings with any other platform builds.
-
-
-WHAT'S MISSING HERE
-===================
-
-    - a section on basic concepts (or maybe it doesn't belong here?)
-    - a section on getting started (C++, Python, Tcl all differ - point to
-      the respective intro pages)
-    - maybe a small sample for each of C++ / Tcl / Python, to give an idea
-    - mention TclKit, scripted docs (WiKit/Tequila?), VFS?
-    - I forgot... please tell me :)

-For your convenience and allowed by zlib's license terms:
-http://www.gzip.org/zlib/zlib_license.html a copy of the zlib source
-is bundled with SimGear in $(top_srcdir)/src-libs/.  You must have
-zlib installed before you can build SimGear.
+zlib is prerequisite for compiling SimGear and FlightGear.  You can fetch
+the latest version of zlib from:
 
-- Most linux distributions have a zlib package.  For linux
-  developers, we recommend ysou install your distributions package
-  rather than building from source.
+    http://www.zlib.net
 
-- Cygwin installs zlib automatically.
+Most modern unix distributions (and cygwin) come with a version of zlib
+already installed or available to install as a package.
 
-- For developers on most other platforms, you will have to build
-  zlib from source and install it yourself.  For your convenience a
-  tar ball of the zlib source is included with the simgear source
-  distribution.  Untar the zlib source, and follow the included
-  build and installation instructions.
-
-Once zlib is installed you can return to configuring and building
-Simgear.
-
-We now send you to the official zlib README ...

-
-zlib 1.1.4 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://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate
-format) and rfc1952.txt (gzip format). These documents are also available in
-other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact jloup@gzip.org). A usage
-example of the library is given in the file example.c which also tests that
-the library is working correctly. Another example is given in the file
-minigzip.c. The compression library itself is composed of all source files
-except example.c and minigzip.c.
-
-To compile all files and run the test program, follow the instructions
-given at the top of Makefile. In short "make test; make install"
-should work for most machines. For Unix: "./configure; make test; make install"
-For MSDOS, use one of the special makefiles such as Makefile.msc.
-For VMS, use Make_vms.com or descrip.mms.
-
-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://www.zlib.org or http://www.gzip.org/zlib/
-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://www.gzip.org/zlib/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 in
-http://dogma.net/markn/articles/zlibtool/zlibtool.htm
-
-The changes made in version 1.1.4 are documented in the file ChangeLog.
-The only changes made since 1.1.3 are bug corrections:
-
-- ZFREE was repeated on same allocation on some error conditions.
-  This creates a security problem described in
-  http://www.zlib.org/advisory-2002-03-11.txt
-- Returned incorrect error (Z_MEM_ERROR) on some invalid data
-- Avoid accesses before window for invalid distances with inflate window
-  less than 32K.
-- force windowBits > 8 to avoid a bug in the encoder for a window size
-  of 256 bytes. (A complete fix will be available in 1.1.5).
-
-The beta version 1.1.5beta includes many more changes. A new official
-version 1.1.5 will be released as soon as extensive testing has been
-completed on it.
-
-
-Unsupported third party contributions are provided in directory "contrib".
-
-A Java implementation of zlib is available in the Java Development Kit
-http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
-See the zlib home page http://www.zlib.org for details.
-
-A Perl interface to zlib written by Paul Marquess <pmarquess@bfsec.bt.co.uk>
-is in the CPAN (Comprehensive Perl Archive Network) sites
-http://www.cpan.org/modules/by-module/Compress/
-
-A Python interface to zlib written by A.M. Kuchling <amk@magnet.com>
-is available in Python 1.5 and later versions, see
-http://www.python.org/doc/lib/module-zlib.html
-
-A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com>
-is availlable at http://www.westend.com/~kupries/doc/trf/man/man.html
-
-An experimental package to read and write files in .zip format,
-written on top of zlib by Gilles Vollant <info@winimage.com>, is
-available at http://www.winimage.com/zLibDll/unzip.html
-and also in the contrib/minizip directory of zlib.
-
-
-Notes for some targets:
-
-- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
-  and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
-  The zlib DLL support was initially done by Alessandro Iacopetti and is
-  now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
-  home page at http://www.winimage.com/zLibDll
-
-  From Visual Basic, you can call the DLL functions which do not take
-  a structure as argument: compress, uncompress and all gz* functions.
-  See contrib/visual-basic.txt for more information, or get
-  http://www.tcfb.com/dowseware/cmp-z-it.zip
-
-- 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, BEOS and by some Mac compilers.
-
-- For Turbo C the small model is supported only with reduced performance to
-  avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
-
-- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html
