+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+                    59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+                  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+/** \mainpage SimGear
+ * Simulation, Visualization, and Game development libraries.
+
+ * \section intro Introduction
+ *
+ * SimGear is a collection of libraries which provide a variety of
+ * functionality useful for building simulations, visualizations, and
+ * even games.  All the SimGear code is designed to be portable across
+ * a wide variety of platforms and compilers.  It has primarily been
+ * developed in support of the FlightGear project, but as development
+ * moves forward, we are generalizing the code to make more of it
+ * useful for other types of applications.
+ *
+ * Some of the functionality provide includes
+ *
+ * - Compiler and platform abstractions for many tricky differences.
+ *   (compiler.h)
+ *
+ * - A whole earth tiling/indexing scheme.  (SGBucket)
+ *
+ * - A console debugging output scheme that tracks severity and
+ *   category that can be completely compiled out for a final build release.
+ *   (logstream.hxx)
+ *
+ * - Code to manage "real" time (SGTime), time zones (SGTimeZone), and
+ *   millesecond time differences (SGTimeStamp).
+ *
+ * - Code to calculate accurate positions of sun, moon, stars, and
+ *   planets for a given time, date, season, earth location, etc.
+ *   (SGEphemeris)
+ *
+ * - Code to render a realistic sky dome, cloud layers, sun, moon,
+ *   stars, and planets all with realistic day/night/sunset/sunrise
+ *   effects.  Includes things like correct moon phase, textured moon,
+ *   sun halo, etc. (SGSky is built on top of SGCloudLayer ...)
+ *
+ * - Simple serial (SGSerial), file (SGFile), socket (SGSocket), and
+ *   UDP socket (SGSocketUDP) I/O abstractions.
+ *
+ * - Code to calculate magnetic variation. (SGMagVar)
+ *
+ * - A variety of classes and functions for interpolation tables
+ *   (SGInterpTable), least squares computation (leastsqs.hxx), 3D
+ *   point/vectors (Point3D), 3D polar math and conversions (polar3d.hxx),
+ *   WGS-84 math and conversions (sg_geodesy.hxx), random number abstraction
+ *   (sg_random.h), STL conglomerates for common list types (sg_types.hxx),
+ *   and other vector and linear algebra routines (vector.hxx)
+ *
+ * - An abstraction to hide platform dependent path naming schemes. (SGPath)
+ *
+ * - A C++ streams wrapper to handle compress input/output streams.
+ *   (sg_gzifstream)
+ *
+ * - An optimized "property manager" which associates ascii property
+ *   names with their corresponding value.  This can be a great way to build
+ *   loose linkages between modules, or build linkages/connections that can
+ *   be determined from config files or at runtime.  (SGPropertyNode)
+ *   Also included is a set of functions to dump the property tree into a
+ *   standard xml file and subsequently read/parse a standard xml file and
+ *   rebuild the associated property tree.  (props_io.hxx)
+ *
+ * - Scene management and drawing routines:
+ *   - material property management
+ *   - object management
+ *   - terrain tile management and paging
+ *   - sky dome rendering (with ephemeral objects)
+ *
+ * - Code to handle screen dumps (screen-dump.hxx) and ultra-hires
+ *   tile rendered screen dumps (tr.h)
+ *
+ * - A sound effects manager.  (SGSoundMgr, SGSimpleSound, SGSound)
+ *
+ * - A threading abstraction.  (SGThread)
+ *
+ * - A simple but highly functional XML parser that interfaces nicely
+ *   with the property manager.  (easyxml.hxx)
+
+ * \section supports Supported Platforms
+ * SimGear has been built on the following platforms:
+ *
+ *   - Linux (x86)
+ *   - Windows (MSVC, Cygwin, Mingwin)
+ *   - SGI (native compilers)
+ *   - Mac OS X
+ *   - FreeBSD
+ 
+ * \section depends Dependencies
+ *
+ * SimGear depends on several other open source packages.  These must
+ * be installed before SimGear can be installed:
+ *
+ *   - glut and opengl
+ *   - plib (http://plib.sf.net)
+ *   - metakit
+ *   - zlib
+ *   - libjpeg (optional)
+ *   - pthread (optional)
+ 
+ * \section license Licensing
+ *
+ * SimGear is licensed under the terms of the LGPL

+This document describes how to build SimGear using the supplied workspace and
+project files.  
+
+Unpack the SimGear source file into your work directory.  This creates a new
+subdirectory called SimGear-X.Y.Z.  Rename this to SimGear.  Before we can
+build SimGear you must unpack and build the third party libraries metakit and
+zlib.  Sources for these are included in the SimGear/src-libs directory.
+Unpack these into the top level SimGear directory.  At this point your
+directory structure should look something like this:
+
+<work_dir>/
+  SimGear/
+    metakit-x.y.z/
+    simgear/
+    src-libs/
+    zlib-x.y.z/
+
+Now open the SimGear workspace.  This workspace file contains projects for
+building metakit(mklib), SimGear and zlib.  Select each project as the active
+project and build all.  Order is unimportant since there are no dependencies
+between the projects.
+
+The workspace and project files are generated by a perl script with extra
+input from the am2dsp.cfg file.

+
+=============================================================================
+
+
+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
+  Per Harald Myrvang <perm@stud.cs.uit.no>
+
+
+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.

+ *
+ * Introduction 
+ *
+ * The SGEphemeris class computes and stores the positions of the Sun,
+ * the Moon, the planets, and the brightest stars.  These positions
+ * can then be used to accurately render the dominant visible items in
+ * the Earth's sky. Note, this class isn't intended for use in an
+ * interplanetary/interstellar/intergalactic type application. It is
+ * calculates everything relative to the Earth and is therefore best
+ * suited for Earth centric applications.
+ *
+ * The positions of the various astronomical objects are time
+ * dependent, so to maintain accuracy, you will need to periodically
+ * call the update() method. The SGTime class conveniently provides
+ * the two time related values you need to pass to the update()
+ * method.
