>+        [WPE] Add Qt extension

>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        This new extension is a QML plugin embedding a WPE ViewBackend
>+        implementation. It provides a public API very similar to Qt's
>+        WebView module. It comes with a simple mini-browser implemented in
>+        QML.
>+
>+        QtWPE is known to work with the Wayland-EGL (in GNOME and Weston
>+        compositors) and EGLFS QPAs.
>+
>+        For commodity purposes a Flatpak build manifest is available but
>+        nothing prevents distributors to ship this extension as a
>+        standalone module because it uses a regular QMake build-system
>+        along with WebKit's CMake build-system.

>+		  GNU LIBRARY GENERAL PUBLIC LICENSE
>+		       Version 2, June 1991
>+
>+ Copyright (C) 1991 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 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
>+
>+     Appendix: 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.

>+
>+ Copyright (C) 1991 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 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

>+
>+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

>+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

>+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

>+     Appendix: 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.>

>+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:
