+GNU Lesser General Public License
+=================================
+
+::
+
+                   GNU LESSER GENERAL PUBLIC LICENSE
+                        Version 2.1, February 1999
+
+  Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+         51 Franklin St, Fifth Floor, Boston, MA  02110-1301  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 Lesser GPL.  It also counts
+  as the successor of the GNU Library Public License, version 2, hence
+  the version number 2.1.]
+
+                             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 Lesser General Public License, applies to some
+ specially designated software packages--typically libraries--of the
+ Free Software Foundation and other authors who decide to use it.  You
+ can use it too, but we suggest you first think carefully about whether
+ this license or the ordinary General Public License is the better
+ strategy to use in any particular case, based on the explanations
+ below.
+
+   When we speak of free software, we are referring to freedom of use,
+ 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 and use pieces of
+ it in new free programs; and that you are informed that you can do
+ these things.
+
+   To protect your rights, we need to make restrictions that forbid
+ distributors to deny you these rights or to ask you to surrender these
+ 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 other code 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.
+
+   We protect your rights with a two-step method: (1) we copyright the
+ library, and (2) we offer you this license, which gives you legal
+ permission to copy, distribute and/or modify the library.
+
+   To protect each distributor, we want to make it very clear that
+ there is no warranty for the free library.  Also, if the library is
+ modified by someone else and passed on, the recipients should know
+ that what they have is not the original version, so that the original
+ author's reputation will not be affected by problems that might be
+ introduced by others.
+
+   Finally, software patents pose a constant threat to the existence of
+ any free program.  We wish to make sure that a company cannot
+ effectively restrict the users of a free program by obtaining a
+ restrictive license from a patent holder.  Therefore, we insist that
+ any patent license obtained for a version of the library must be
+ consistent with the full freedom of use specified in this license.
+
+   Most GNU software, including some libraries, is covered by the
+ ordinary GNU General Public License.  This license, the GNU Lesser
+ General Public License, applies to certain designated libraries, and
+ is quite different from the ordinary General Public License.  We use
+ this license for certain libraries in order to permit linking those
+ libraries into non-free programs.
+
+   When a program is linked with a library, whether statically or using
+ a shared library, the combination of the two is legally speaking a
+ combined work, a derivative of the original library.  The ordinary
+ General Public License therefore permits such linking only if the
+ entire combination fits its criteria of freedom.  The Lesser General
+ Public License permits more lax criteria for linking other code with
+ the library.
+
+   We call this license the "Lesser" General Public License because it
+ does Less to protect the user's freedom than the ordinary General
+ Public License.  It also provides other free software developers Less
+ of an advantage over competing non-free programs.  These disadvantages
+ are the reason we use the ordinary General Public License for many
+ libraries.  However, the Lesser license provides advantages in certain
+ special circumstances.
+
+   For example, on rare occasions, there may be a special need to
+ encourage the widest possible use of a certain library, so that it
+ becomes a de-facto standard.  To achieve this, non-free programs must
+ be allowed to use the library.  A more frequent case is that a free
+ library does the same job as widely used non-free libraries.  In this
+ case, there is little to gain by limiting the free library to free
+ software only, so we use the Lesser General Public License.
+
+   In other cases, permission to use a particular library in non-free
+ programs enables a greater number of people to use a large body of
+ free software.  For example, permission to use the GNU C Library in
+ non-free programs enables many more people to use the whole GNU
+ operating system, as well as its variant, the GNU/Linux operating
+ system.
+
+   Although the Lesser General Public License is Less protective of the
+ users' freedom, it does ensure that the user of a program that is
+ linked with the Library has the freedom and the wherewithal to run
+ that program using a modified version of the Library.
+
+   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, whereas the latter must
+ be combined with the library in order to run.
+
+                   GNU LESSER GENERAL PUBLIC LICENSE
+    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+   0. This License Agreement applies to any software library or other
+ program which contains a notice placed by the copyright holder or
+ other authorized party saying it may be distributed under the terms of
+ this Lesser 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 combine 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) Use a suitable shared library mechanism for linking with the
+     Library.  A suitable mechanism is one that (1) uses at run time a
+     copy of the library already present on the user's computer system,
+     rather than copying library functions into the executable, and (2)
+     will operate properly with a modified version of the library, if
+     the user installs one, as long as the modified version is
+     interface-compatible with the version that the work was made with.
+
+     c) 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.
+
+     d) 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.
+
+     e) 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 materials to be 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 with
+ 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 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
+ 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 Lesser General Public

+     version 2.1 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
+     Lesser General Public License for more details.
+
+     You should have received a copy of the GNU Lesser General Public

+     Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  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

+                          Version 2.0beta4, October 2000
+
+                          Copyright (C) 2000, Larry Wall.
+         Everyone is permitted to copy and distribute verbatim copies
+          of this license document, but changing it is not allowed.
+
+                                   Preamble
+
+ This copyright license states the terms under which a given free
+ software Package may be copied, modified and/or redistributed, while the
+ Originator(s) maintain some artistic control over the future development
+ of that Package (at least as much artistic control as can be given under
+ copyright law while still making the Package open source and free software).
+
+ This license is bound by copyright law, and thus it legally applies only
+ to works which the copyright holder has permitted copying, distribution
+ or modification under the terms of the Artistic License, Version 2.0.
+
+ You are reminded that You are always permitted to make arrangements
+ wholly outside of a given copyright license directly with the copyright
+ holder(s) of a given Package. If the terms of this license impede your
+ ability to make full use of the Package, You are encouraged to contact
+ the copyright holder(s) and seek a different licensing arrangement.
+
+                                 Definitions
+
+ "Package" refers to the collection of files distributed by the
+ Originator(s), and derivatives of that collection of files created
+ through textual modification.
+
+ "Standard Version" refers to the Package if it has not been modified, or
+ has been modified only in ways suggested by the Originator(s).
+
+ "Modified Version" refers to the Package, if it has been changed by You
+ via textual modification of the source code, and such changes were not
+ suggested by the Originator(s).
+
+ "Originator" refers to the author(s) and/or copyright holder(s) of the
+ Standard Version of the Package.
+
+ "You" and "Your" refers to any person who would like to copy,
+ distribute, or modify the Package.
+
+ "Distribution Fee" is any fee that You charge for providing a copy of
+ this Package to another party. It does not refer to licensing fees.
+
+ "Freely Available" means that:
+
+        (a) no fee is charged for the right to use the item (though a
+            Distribution Fee may be charged).
+
+        (b) recipients of the item may redistribute it under the same
+            conditions they received it.
+
+        (c) If the item is a binary, object code, bytecode, the complete
+            corresponding machine-readable source code is included with the
+            item.
+
+
+          Permission for Use and Modification Without Redistribution
+
+   (1) You are permitted to use the Standard Version and create and use
+       Modified Versions for any purpose without restriction, provided that
+       you do not redistribute the Modified Version to others outside of your
+       company or organization.
+
+
+            Permissions for Redistribution of the Standard Version
+
+   (2) You may make available verbatim copies of the source code of the
+       Standard Version of this Package in any medium without restriction,
+       either gratis or for a Distribution Fee, provided that you duplicate
+       all of the original copyright notices and associated disclaimers.  At
+       Your discretion, such verbatim copies may or may not include compiled
+       bytecode, object code or binary versions of the corresponding source
+       code in the same medium.
+
+   (3) You may apply any bug fixes, portability changes, and other
+       modifications made available from any of the Originator(s).  The
+       resulting modified Package will still be considered the Standard
+       Version, and may be copied, modified and redistributed under the terms
+       of the original license of the Standard Version as if it were the
+       Standard Version.
+
+
+  Permissions for Redistribution of Modified Versions of the Package as Source
+
+   (4) You may modify your copy of the source code of this Package in any way
+       and distribute that Modified Version (either gratis or for a
+       Distribution Fee, and with or without a corresponding binary, bytecode
+       or object code version of the Modified Version) provided that You
+       clearly indicate what changes You made to the Package, and provided
+       that You do at least ONE of the following:
+
+        (a) make the Modified Version available to the Originator(s) of the
+            Standard Version, under the exact license of the Standard
+            Version, so that the Originator(s) may include your modifications
+            into the Standard Version (at their discretion).
+
+        (b) modify any installation scripts and procedures so that
+            installation of the Modified Version will never conflict with an
+            installation of the Standard Version, include for each program
+            installed by the Modified Version clear documentation describing
+            how it differs from the Standard Version, and rename your
+            Modified Version so that the name is substantially different from
+            the Standard Version.
+
+        (c) permit and encourage anyone who receives a copy of the Modified
+            Version permission to make your modifications Freely Available in
+            some specific way.                                               
+
+       If Your Modified Version is in turn derived from a Modified Version
+       made by a third party, then You are still required to ensure that Your
+       Modified Version complies with the requirements of this license.
+
+
+       Permissions for Redistribution of Non-Source Versions of Package
+
+   (5) You may distribute binary, object code, bytecode or other non-source
+       versions of the Standard Version of the Package, provided that you
+       include complete instructions on where to get the source code of the
+       Standard Version.  Such instructions must be valid at the time of Your
+       distribution.  If these instructions, at any time while You are
+       carrying our such distribution, become invalid, you must provide new
+       instructions on demand or cease further distribution.  If You cease
+       distribution within thirty days after You become aware that the
+       instructions are invalid, then You do not forfeit any of Your rights
+       under this license.
+
+   (6) You may distribute binary, object code, bytecode or other non-source
+       versions of a Modified Version provided that You do at least ONE of
+       the following:
+
+        (a) include a copy of the corresponding source code for the Modified
+            Version under the terms indicated in (4).
+
+        (b) ensure that the installation of Your non-source Modified Version
+            does not conflict in any way with an installation of the Standard
+            Version, include for each program installed by the Modified
+            Version clear documentation describing how it differs from the
+            Standard Version, and rename your Modified Version so that the
+            name is substantially different from the Standard Version.
+
+        (c) ensure that the Modified Version includes notification of the
+            changes made from the Standard Version, and offer to provide
+            machine-readable source code (under a license that permits making
+            that source code Freely Available) of the Modified Version via
+            mail order.
+
+
+         Permissions for Inclusion of the Package in Aggregate Works
+
+   (7) You may aggregate this Package (either the Standard Version or
+       Modified Version) with other packages and distribute the resulting
+       aggregation provided that You do not charge a licensing fee for the
+       Package.  Distribution Fees are permitted, and licensing fees for
+       other packages in the aggregation are permitted.  Your permission to
+       distribute Standard or Modified Versions of the Package is still
+       subject to the other terms set forth in other sections of this
+       license.
+
+   (8) In addition to the permissions given elsewhere by this license, You
+       are also permitted to link Modified and Standard Versions of this
+       Package with other works and distribute the result without
+       restriction, provided You have produced binary program(s) that do not
+       overtly expose the interfaces of the Package.  This includes
+       permission to embed the Package in a larger work of your own without
+       exposing a direct interface to the Package.  This also includes
+       permission to build stand-alone binary or bytecode versions of your
+       scripts that require the Package, but do not otherwise give the casual
+       user direct access to the Package itself.
+
+
+         Items That are Never Considered Part of a Modified Version Package
+
+   (9) Works (including, but not limited to, subroutines and scripts) that
+       you have linked or aggregated with the Package that merely extend or
+       make use of the Package, but are not intended to cause the Package to
+       operate differently from the Standard Version, do not, by themselves,
+       cause the Package to be a Modified Version.  In addition, such works
+       are not considered parts of the Package itself, and are not bound by
+       the terms of the Package's license.
+
+
+               Acceptance of License and Disclaimer of Warranty
+
+  (10) You are not required to accept this License, since you have not signed
+       it.  However, nothing else grants you permission to copy, modify or
+       distribute the Standard or Modified Versions of the Package.  These
+       actions are prohibited by copyright law if you do not accept this
+       License.  Therefore, by copying, modifying or distributing Standard
+       and Modified Versions of the Package, you indicate your acceptance of
+       the license of the Package.
+
+
+  (11) Disclaimer of Warranty:
+
+        THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS
+        "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT
