+ Preamble to the Gnu Lesser General Public License
+
+
+Copyright (c) 2000 Franz Incorporated, Berkeley, CA 94704
+
+The concept of the GNU Lesser General Public License version 2.1
+("LGPL") has been adopted to govern the use and distribution of
+above-mentioned application. However, the LGPL uses terminology that
+is more appropriate for a program written in C than one written in
+Lisp. Nevertheless, the LGPL can still be applied to a Lisp program if
+certain clarifications are made. This document details those
+clarifications. Accordingly, the license for the open-source Lisp
+applications consists of this document plus the LGPL. Wherever there
+is a conflict between this document and the LGPL, this document takes
+precedence over the LGPL.
+
+A "Library" in Lisp is a collection of Lisp functions, data and
+foreign modules. The form of the Library can be Lisp source code (for
+processing by an interpreter) or object code (usually the result of
+compilation of source code or built with some other
+mechanisms). Foreign modules are object code in a form that can be
+linked into a Lisp executable. When we speak of functions we do so in
+the most general way to include, in addition, methods and unnamed
+functions. Lisp "data" is also a general term that includes the data
+structures resulting from defining Lisp classes. A Lisp application
+may include the same set of Lisp objects as does a Library, but this
+does not mean that the application is necessarily a "work based on the
+Library" it contains.
+
+The Library consists of everything in the distribution file set before
+any modifications are made to the files. If any of the functions or
+classes in the Library are redefined in other files, then those
+redefinitions ARE considered a work based on the Library. If
+additional methods are added to generic functions in the Library,
+those additional methods are NOT considered a work based on the
+Library. If Library classes are subclassed, these subclasses are NOT
+considered a work based on the Library. If the Library is modified to
+explicitly call other functions that are neither part of Lisp itself
+nor an available add-on module to Lisp, then the functions called by
+the modified Library ARE considered a work based on the Library. The
+goal is to ensure that the Library will compile and run without
+getting undefined function errors.
+
+It is permitted to add proprietary source code to the Library, but it
+must be done in a way such that the Library will still run without
+that proprietary code present. Section 5 of the LGPL distinguishes
+between the case of a library being dynamically linked at runtime and
+one being statically linked at build time. Section 5 of the LGPL
+states that the former results in an executable that is a "work that
+uses the Library." Section 5 of the LGPL states that the latter
+results in one that is a "derivative of the Library", which is
+therefore covered by the LGPL. Since Lisp only offers one choice,
+which is to link the Library into an executable at build time, we
+declare that, for the purpose applying the LGPL to the Library, an
+executable that results from linking a "work that uses the Library"
+with the Library is considered a "work that uses the Library" and is
+therefore NOT covered by the LGPL.
+
+Because of this declaration, section 6 of LGPL is not applicable to
+the Library. However, in connection with each distribution of this
+executable, you must also deliver, in accordance with the terms and
+conditions of the LGPL, the source code of Library (or your derivative
+thereof) that is incorporated into this executable.
+
+
+
+
+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. 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
