	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.

	   	   GNU LESSER GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.


  This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

  0. Additional Definitions. 

  As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

  "The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

  An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

  A "Combined Work" is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

  1. Exception to Section 3 of the GNU GPL.

  You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

  2. Conveying Modified Versions.

  If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or

   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.

  3. Object Code Incorporating Material from Library Header Files.

  The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the object code with a copy of the GNU GPL and this license
   document.

  4. Combined Works.

  You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.

   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.

   d) Do one of the following:

       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.

       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version. 

   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)

  5. Combined Libraries.

  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 that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.

   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.

  6. Revised Versions of the GNU Lesser General Public License.

  The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser 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 as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

  If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.
