+GNU GENERAL PUBLIC LICENSE
+				Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+				Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, 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 software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, 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 redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+			GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+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 give any other recipients of the Program a copy of this License
+along with the Program.
+
+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 Program or any portion
+of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
+	stating that you changed the files and the date of any change.
+
+	b) You must cause any work that you distribute or publish, that in
+	whole or in part contains or is derived from the Program or any
+	part thereof, to be licensed as a whole at no charge to all third
+	parties under the terms of this License.
+
+	c) If the modified program normally reads commands interactively
+	when run, you must cause it, when started running for such
+	interactive use in the most ordinary way, to print or display an
+	announcement including an appropriate copyright notice and a
+	notice that there is no warranty (or else, saying that you provide
+	a warranty) and that users may redistribute the program under
+	these conditions, and telling the user how to view a copy of this
+	License.  (Exception: if the Program itself is interactive but
+	does not normally print such an announcement, your work based on
+	the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+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 Program, 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 Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+	a) 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; or,
+
+	b) Accompany it with a written offer, valid for at least three
+	years, to give any third party, for a charge no more than your
+	cost of physically performing source distribution, a complete
+	machine-readable copy of the corresponding source code, to be
+	distributed under the terms of Sections 1 and 2 above on a medium
+	customarily used for software interchange; or,
+
+	c) Accompany it with the information you received as to the offer
+	to distribute corresponding source code.  (This alternative is
+	allowed only for noncommercial distribution and only if you
+	received the program in object code or executable form with such
+	an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, 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 executable.  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.
+
+If distribution of executable or 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 counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program 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.
+
+  5. 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 Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program 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.
+
+  7. 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 Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program 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 Program.
+
+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.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program 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.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the 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 Program
+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 Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, 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
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), 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 Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  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 program's name and a brief idea of what it does.>
+	Copyright (C) <year>  <name of author>
+
+	This program is free software; you can redistribute it and/or modify
+	it under the terms of the GNU General Public License as published by
+	the Free Software Foundation; either version 2 of the License, or
+	(at your option) any later version.
+
+	This program 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 General Public License for more details.
+
+	You should have received a copy of the GNU General Public License
+	along with this program; if not, write to the Free Software
+	Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+	Gnomovision version 69, Copyright (C) year name of author
+	Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+	This is free software, and you are welcome to redistribute it
+	under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+// Original file header of ParseXL (used as the base for this class):
+// --------------------------------------------------------------------------------
+// Adapted from Excel_Spreadsheet_Reader developed by users bizon153,
+// trex005, and mmp11 (SourceForge.net)
+// http://sourceforge.net/projects/phpexcelreader/
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.00 ...
+//	 Modelled moreso after Perl Excel Parse/Write modules
+//	 Added Parse_Excel_Spreadsheet object
+//		 Reads a whole worksheet or tab as row,column array or as
+//		 associated hash of indexed rows and named column fields
+//	 Added variables for worksheet (tab) indexes and names
+//	 Added an object call for loading individual woorksheets
+//	 Changed default indexing defaults to 0 based arrays
+//	 Fixed date/time and percent formats
+//	 Includes patches found at SourceForge...
+//		 unicode patch by nobody
+//		 unpack("d") machine depedency patch by matchy
+//		 boundsheet utf16 patch by bjaenichen
+//	 Renamed functions for shorter names
+//	 General code cleanup and rigor, including <80 column width
+//	 Included a testcase Excel file and PHP example calls
+//	 Code works for PHP 5.x
+
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.10 ...
+// http://sourceforge.net/tracker/index.php?func=detail&aid=1466964&group_id=99160&atid=623334
+//	 Decoding of formula conditions, results, and tokens.
+//	 Support for user-defined named cells added as an array "namedcells"
+//		 Patch code for user-defined named cells supports single cells only.
+//		 NOTE: this patch only works for BIFF8 as BIFF5-7 use a different
+//		 external sheet reference structure

++ Removed conditional logic from top of Matrix class.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the 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
+    License as published by the Free Software Foundation; either
+    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
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+  //   are added in the archive. See the parameters description for the
+  //   supported format of $p_filelist.

+  //   $p_filelist : An array containing file or directory names, or
+  //                 a string containing one filename or one directory name, or
+  //                 a string containing a list of filenames and/or directory
+  //                 names separated by spaces.
+  //   $p_add_dir : A path to add before the real path of the archived file,
+  //                in order to have it memorized in the archive.
+  //   $p_remove_dir : A path to remove from the real path of the file to archive,
+  //                   in order to have a shorter path memorized in the archive.
+  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
+  //                   is removed first, before $p_add_dir is added.

+1 - Introduction
+================
+
+  PclZip is a library that allow you to manage a Zip archive.
+
+  Full documentation about PclZip can be found here : http://www.phpconcept.net/pclzip
+
+2 - What's new
+==============
+
+  Version 2.8.2 :
+    - PCLZIP_CB_PRE_EXTRACT and PCLZIP_CB_POST_EXTRACT are now supported with 
+      extraction as a string (PCLZIP_OPT_EXTRACT_AS_STRING). The string
+      can also be modified in the post-extract call back.
+    **Bugs correction :
+    - PCLZIP_OPT_REMOVE_ALL_PATH was not working correctly    
+    - Remove use of eval() and do direct call to callback functions
+    - Correct support of 64bits systems (Thanks to WordPress team)
+
+  Version 2.8.1 :
+    - Move option PCLZIP_OPT_BY_EREG to PCLZIP_OPT_BY_PREG because ereg() is
+      deprecated in PHP 5.3. When using option PCLZIP_OPT_BY_EREG, PclZip will
+      automatically replace it by PCLZIP_OPT_BY_PREG.
+  
+  Version 2.8 :
+    - Improve extraction of zip archive for large files by using temporary files
+      This feature is working like the one defined in r2.7.
+      Options are renamed : PCLZIP_OPT_TEMP_FILE_ON, PCLZIP_OPT_TEMP_FILE_OFF,
+      PCLZIP_OPT_TEMP_FILE_THRESHOLD
+    - Add a ratio constant PCLZIP_TEMPORARY_FILE_RATIO to configure the auto
+      sense of temporary file use.
+    - Bug correction : Reduce filepath in returned file list to remove ennoying
+      './/' preambule in file path.
+
+  Version 2.7 :
+    - Improve creation of zip archive for large files :
+      PclZip will now autosense the configured memory and use temporary files
+      when large file is suspected.
+      This feature can also ne triggered by manual options in create() and add()
+      methods. 'PCLZIP_OPT_ADD_TEMP_FILE_ON' force the use of temporary files,
+      'PCLZIP_OPT_ADD_TEMP_FILE_OFF' disable the autosense technic, 
+      'PCLZIP_OPT_ADD_TEMP_FILE_THRESHOLD' allow for configuration of a size
+      threshold to use temporary files.
+      Using "temporary files" rather than "memory" might take more time, but
+      might give the ability to zip very large files :
+      Tested on my win laptop with a 88Mo file :
+        Zip "in-memory" : 18sec (max_execution_time=30, memory_limit=180Mo)
+        Zip "tmporary-files" : 23sec (max_execution_time=30, memory_limit=30Mo)
+    - Replace use of mktime() by time() to limit the E_STRICT error messages.
+    - Bug correction : When adding files with full windows path (drive letter)
+      PclZip is now working. Before, if the drive letter is not the default
+      path, PclZip was not able to add the file.
+
+  Version 2.6 :
+    - Code optimisation
+    - New attributes PCLZIP_ATT_FILE_COMMENT gives the ability to
+      add a comment for a specific file. (Don't really know if this is usefull)
+    - New attribute PCLZIP_ATT_FILE_CONTENT gives the ability to add a string 
+      as a file.
+    - New attribute PCLZIP_ATT_FILE_MTIME modify the timestamp associated with
+      a file.
+    - Correct a bug. Files archived with a timestamp with 0h0m0s were extracted
+      with current time
+    - Add CRC value in the informations returned back for each file after an
+      action.
+    - Add missing closedir() statement.
+    - When adding a folder, and removing the path of this folder, files were
+      incorrectly added with a '/' at the beginning. Which means files are 
+      related to root in unix systems. Corrected.
+    - Add conditional if before constant definition. This will allow users
+      to redefine constants without changing the file, and then improve
+      upgrade of pclzip code for new versions.
+  
+  Version 2.5 :
+    - Introduce the ability to add file/folder with individual properties (file descriptor).
+      This gives for example the ability to change the filename of a zipped file.
+      . Able to add files individually
+      . Able to change full name
+      . Able to change short name
+      . Compatible with global options
+    - New attributes : PCLZIP_ATT_FILE_NAME, PCLZIP_ATT_FILE_NEW_SHORT_NAME, PCLZIP_ATT_FILE_NEW_FULL_NAME
+    - New error code : PCLZIP_ERR_INVALID_ATTRIBUTE_VALUE
+    - Add a security control feature. PclZip can extract any file in any folder
+      of a system. People may use this to upload a zip file and try to override
+      a system file. The PCLZIP_OPT_EXTRACT_DIR_RESTRICTION will give the
+      ability to forgive any directory transversal behavior.
+    - New PCLZIP_OPT_EXTRACT_DIR_RESTRICTION : check extraction path
+    - New error code : PCLZIP_ERR_DIRECTORY_RESTRICTION
+    - Modification in PclZipUtilPathInclusion() : dir and path beginning with ./ will be prepend
+      by current path (getcwd())
+  
+  Version 2.4 :
+    - Code improvment : try to speed up the code by removing unusefull call to pack()
+    - Correct bug in delete() : delete() should be called with no argument. This was not
+      the case in 2.3. This is corrected in 2.4.
+    - Correct a bug in path_inclusion function. When the path has several '../../', the
+      result was bad.
+    - Add a check for magic_quotes_runtime configuration. If enabled, PclZip will 
+      disable it while working and det it back to its original value.
+      This resolve a lots of bad formated archive errors.
+    - Bug correction : PclZip now correctly unzip file in some specific situation,
+      when compressed content has same size as uncompressed content.
+    - Bug correction : When selecting option 'PCLZIP_OPT_REMOVE_ALL_PATH', 
+      directories are not any more created.
+    - Code improvment : correct unclosed opendir(), better handling of . and .. in
+      loops.
+
+
+  Version 2.3 :
+    - Correct a bug with PHP5 : affecting the value 0xFE49FFE0 to a variable does not
+      give the same result in PHP4 and PHP5 ....
+
+  Version 2.2 :
+    - Try development of PCLZIP_OPT_CRYPT .....
+      However this becomes to a stop. To crypt/decrypt I need to multiply 2 long integers,
+      the result (greater than a long) is not supported by PHP. Even the use of bcmath
+      functions does not help. I did not find yet a solution ...;
+    - Add missing '/' at end of directory entries
+    - Check is a file is encrypted or not. Returns status 'unsupported_encryption' and/or
+      error code PCLZIP_ERR_UNSUPPORTED_ENCRYPTION.
+    - Corrected : Bad "version need to extract" field in local file header
+    - Add private method privCheckFileHeaders() in order to check local and central
+      file headers. PclZip is now supporting purpose bit flag bit 3. Purpose bit flag bit 3 gives
+      the ability to have a local file header without size, compressed size and crc filled.
+    - Add a generic status 'error' for file status
+    - Add control of compression type. PclZip only support deflate compression method.
+      Before v2.2, PclZip does not check the compression method used in an archive while
+      extracting. With v2.2 PclZip returns a new error status for a file using an unsupported
+      compression method. New status is "unsupported_compression". New error code is
+      PCLZIP_ERR_UNSUPPORTED_COMPRESSION.
+    - Add optional attribute PCLZIP_OPT_STOP_ON_ERROR. This will stop the extract of files
+      when errors like 'a folder with same name exists' or 'a newer file exists' or
+      'a write protected file' exists, rather than set a status for the concerning file
+      and resume the extract of the zip.
+    - Add optional attribute PCLZIP_OPT_REPLACE_NEWER. This will force, during an extract' the
+      replacement of the file, even if a  newer version of the file exists.
+      Note that today if a file with the same name already exists but is older it will be
+      replaced by the extracted one.
+    - Improve PclZipUtilOption()
+    - Support of zip archive with trailing bytes. Before 2.2, PclZip checks that the central
+      directory structure is the last data in the archive. Crypt encryption/decryption of
+      zip archive put trailing 0 bytes after decryption. PclZip is now supporting this.
+
+  Version 2.1 :
+    - Add the ability to abort the extraction by using a user callback function.
+      The user can now return the value '2' in its callback which indicates to stop the
+      extraction. For a pre call-back extract is stopped before the extration of the current
+      file. For a post call back, the extraction is stopped after.
+    - Add the ability to extract a file (or several files) directly in the standard output.
+      This is done by the new parameter PCLZIP_OPT_EXTRACT_IN_OUTPUT with method extract().
+    - Add support for parameters PCLZIP_OPT_COMMENT, PCLZIP_OPT_ADD_COMMENT,
+      PCLZIP_OPT_PREPEND_COMMENT. This will create, replace, add, or prepend comments
+      in the zip archive.
+    - When merging two archives, the comments are not any more lost, but merged, with a 
+      blank space separator.
+    - Corrected bug : Files are not deleted when all files are asked to be deleted.
+    - Corrected bug : Folders with name '0' made PclZip to abort the create or add feature.
+
+
+  Version 2.0 :
+    ***** Warning : Some new features may break the backward compatibility for your scripts.
+                    Please carefully read the readme file.
+    - Add the ability to delete by Index, name and regular expression. This feature is 
+      performed by the method delete(), which uses the optional parameters
+      PCLZIP_OPT_BY_INDEX, PCLZIP_OPT_BY_NAME, PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG.
+    - Add the ability to extract by regular expression. To extract by regexp you must use the method
+      extract(), with the option PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG 
+      (depending if you want to use ereg() or preg_match() syntax) followed by the 
+      regular expression pattern.
+    - Add the ability to extract by index, directly with the extract() method. This is a
+      code improvment of the extractByIndex() method.
+    - Add the ability to extract by name. To extract by name you must use the method
+      extract(), with the option PCLZIP_OPT_BY_NAME followed by the filename to
+      extract or an array of filenames to extract. To extract all a folder, use the folder
+      name rather than the filename with a '/' at the end.
+    - Add the ability to add files without compression. This is done with a new attribute
+      which is PCLZIP_OPT_NO_COMPRESSION.
+    - Add the attribute PCLZIP_OPT_EXTRACT_AS_STRING, which allow to extract a file directly
+      in a string without using any file (or temporary file).
+    - Add constant PCLZIP_SEPARATOR for static configuration of filename separators in a single string.
+      The default separator is now a comma (,) and not any more a blank space.
+      THIS BREAK THE BACKWARD COMPATIBILITY : Please check if this may have an impact with
+      your script.
+    - Improve algorythm performance by removing the use of temporary files when adding or 
+      extracting files in an archive.
+    - Add (correct) detection of empty filename zipping. This can occurs when the removed
+      path is the same
+      as a zipped dir. The dir is not zipped (['status'] = filtered), only its content.
+    - Add better support for windows paths (thanks for help from manus@manusfreedom.com).
+    - Corrected bug : When the archive file already exists with size=0, the add() method
+      fails. Corrected in 2.0.
+    - Remove the use of OS_WINDOWS constant. Use php_uname() function rather.
+    - Control the order of index ranges in extract by index feature.
+    - Change the internal management of folders (better handling of internal flag).
+
+
+  Version 1.3 :
+    - Removing the double include check. This is now done by include_once() and require_once()
+      PHP directives.
+    - Changing the error handling mecanism : Remove the use of an external error library.
+      The former PclError...() functions are replaced by internal equivalent methods.
+      By changing the environment variable PCLZIP_ERROR_EXTERNAL you can still use the former library.
+      Introducing the use of constants for error codes rather than integer values. This will help
+      in futur improvment.
+      Introduction of error handling functions like errorCode(), errorName() and errorInfo().
+    - Remove the deprecated use of calling function with arguments passed by reference.
+    - Add the calling of extract(), extractByIndex(), create() and add() functions
+      with variable options rather than fixed arguments.
+    - Add the ability to remove all the file path while extracting or adding,
+      without any need to specify the path to remove.
+      This is available for extract(), extractByIndex(), create() and add() functionS by using
+      the new variable options parameters :
+      - PCLZIP_OPT_REMOVE_ALL_PATH : by indicating this option while calling the fct.
+    - Ability to change the mode of a file after the extraction (chmod()).
+      This is available for extract() and extractByIndex() functionS by using
+      the new variable options parameters.
+      - PCLZIP_OPT_SET_CHMOD : by setting the value of this option.
+    - Ability to definition call-back options. These call-back will be called during the adding,
+      or the extracting of file (extract(), extractByIndex(), create() and add() functions) :
+      - PCLZIP_CB_PRE_EXTRACT : will be called before each extraction of a file. The user
+        can trigerred the change the filename of the extracted file. The user can triggered the
+        skip of the extraction. This is adding a 'skipped' status in the file list result value.
+      - PCLZIP_CB_POST_EXTRACT : will be called after each extraction of a file.
+        Nothing can be triggered from that point.
+      - PCLZIP_CB_PRE_ADD : will be called before each add of a file. The user
+        can trigerred the change the stored filename of the added file. The user can triggered the
+        skip of the add. This is adding a 'skipped' status in the file list result value.
+      - PCLZIP_CB_POST_ADD : will be called after each add of a file.
+        Nothing can be triggered from that point.
+    - Two status are added in the file list returned as function result : skipped & filename_too_long
+      'skipped' is used when a call-back function ask for skipping the file.
+      'filename_too_long' is used while adding a file with a too long filename to archive (the file is
+      not added)
+    - Adding the function PclZipUtilPathInclusion(), that check the inclusion of a path into
+      a directory.
+    - Add a check of the presence of the archive file before some actions (like list, ...)
+    - Add the initialisation of field "index" in header array. This means that by
+      default index will be -1 when not explicitly set by the methods.
+
+  Version 1.2 :
+    - Adding a duplicate function.
+    - Adding a merge function. The merge function is a "quick merge" function,
+      it just append the content of an archive at the end of the first one. There
+      is no check for duplicate files or more recent files.
+    - Improve the search of the central directory end.
+
+  Version 1.1.2 :
+
+    - Changing the license of PclZip. PclZip is now released under the GNU / LGPL license
+      (see License section).
+    - Adding the optional support of a static temporary directory. You will need to configure
+      the constant PCLZIP_TEMPORARY_DIR if you want to use this feature.
+    - Improving the rename() function. In some cases rename() does not work (different
+      Filesystems), so it will be replaced by a copy() + unlink() functions.
+
+  Version 1.1.1 :
+
+    - Maintenance release, no new feature.
+
+  Version 1.1 :
+
+    - New method Add() : adding files in the archive
+    - New method ExtractByIndex() : partial extract of the archive, files are identified by
+      their index in the archive
+    - New method DeleteByIndex() : delete some files/folder entries from the archive,
+      files are identified by their index in the archive.
+    - Adding a test of the zlib extension presence. If not present abort the script.
+
+  Version 1.0.1 :
+
+    - No new feature
+
+
+3 - Corrected bugs
+==================
+
+  Corrected in Version 2.0 :
+    - Corrected : During an extraction, if a call-back fucntion is used and try to skip
+                  a file, all the extraction process is stopped. 
+
+  Corrected in Version 1.3 :
+    - Corrected : Support of static synopsis for method extract() is broken.
+    - Corrected : invalid size of archive content field (0xFF) should be (0xFFFF).
+    - Corrected : When an extract is done with a remove_path parameter, the entry for
+      the directory with exactly the same path is not skipped/filtered.
+    - Corrected : extractByIndex() and deleteByIndex() were not managing index in the
+      right way. For example indexes '1,3-5,11' will only extract files 1 and 11. This
+      is due to a sort of the index resulting table that puts 11 before 3-5 (sort on
+      string and not interger). The sort is temporarilly removed, this means that
+      you must provide a sorted list of index ranges.
+
+  Corrected in Version 1.2 :
+
+    - Nothing.
+
+  Corrected in Version 1.1.2 :
+
+    - Corrected : Winzip is unable to delete or add new files in a PclZip created archives.
+
+  Corrected in Version 1.1.1 :
+
+    - Corrected : When archived file is not compressed (0% compression), the
+      extract method fails.
+
+  Corrected in Version 1.1 :
+
+    - Corrected : Adding a complete tree of folder may result in a bad archive
+      creation.
+
+  Corrected in Version 1.0.1 :
+
+    - Corrected : Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024).
+
+
+4 - Known bugs or limitations
+=============================
+
+  Please publish bugs reports in SourceForge :
+    http://sourceforge.net/tracker/?group_id=40254&atid=427564
+
+  In Version 2.x :
+    - PclZip does only support file uncompressed or compressed with deflate (compression method 8)
+    - PclZip does not support password protected zip archive
+    - Some concern were seen when changing mtime of a file while archiving. 
+      Seems to be linked to Daylight Saving Time (PclTest_changing_mtime).
+
+  In Version 1.2 :
+
+    - merge() methods does not check for duplicate files or last date of modifications.
+
+  In Version 1.1 :
+
+    - Limitation : Using 'extract' fields in the file header in the zip archive is not supported.
+    - WinZip is unable to delete a single file in a PclZip created archive. It is also unable to
+      add a file in a PclZip created archive. (Corrected in v.1.2)
+
+  In Version 1.0.1 :
+
+    - Adding a complete tree of folder may result in a bad archive
+      creation. (Corrected in V.1.1).
+    - Path given to methods must be in the unix format (/) and not the Windows format (\).
+      Workaround : Use only / directory separators.
+    - PclZip is using temporary files that are sometime the name of the file with a .tmp or .gz
+      added suffix. Files with these names may already exist and may be overwritten.
+      Workaround : none.
+    - PclZip does not check if the zlib extension is present. If it is absent, the zip
+      file is not created and the lib abort without warning.
+      Workaround : enable the zlib extension on the php install
+
+  In Version 1.0 :

+/**
+ * PHPExcel_Worksheet_HeaderFooter
+ *
+ * <code>
+ * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:
+ *
+ * There are a number of formatting codes that can be written inline with the actual header / footer text, which
+ * affect the formatting in the header or footer.
+ *
+ * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
+ * the second line (center section).
+ * 		&CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
+ *
+ * General Rules:
+ * There is no required order in which these codes must appear.
+ *
+ * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
+ * - strikethrough
+ * - superscript
+ * - subscript
+ * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
+ * while the first is ON.
+ * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When
+ * two or more occurrences of this section marker exist, the contents from all markers are concatenated, in the
+ * order of appearance, and placed into the left section.
+ * &P - code for "current page #"
+ * &N - code for "total pages"
+ * &font size - code for "text font size", where font size is a font size in points.
+ * &K - code for "text font color"
+ * RGB Color is specified as RRGGBB
+ * Theme Color is specifed as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/shade
+ * value, NN is the tint/shade value.
+ * &S - code for "text strikethrough" on / off
+ * &X - code for "text super script" on / off
+ * &Y - code for "text subscript" on / off
+ * &C - code for "center section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the center section.
+ *
+ * &D - code for "date"
+ * &T - code for "time"
+ * &G - code for "picture as background"
+ * &U - code for "text single underline"
+ * &E - code for "double underline"
+ * &R - code for "right section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the right section.
+ * &Z - code for "this workbook's file path"
+ * &F - code for "this workbook's file name"
+ * &A - code for "sheet tab name"
+ * &+ - code for add to page #.
+ * &- - code for subtract from page #.
+ * &"font name,font type" - code for "text font name" and "text font type", where font name and font type
+ * are strings specifying the name and type of the font, separated by a comma. When a hyphen appears in font
+ * name, it means "none specified". Both of font name and font type can be localized values.
+ * &"-,Bold" - code for "bold font style"
+ * &B - also means "bold font style".
+ * &"-,Regular" - code for "regular font style"
+ * &"-,Italic" - code for "italic font style"
+ * &I - also means "italic font style"
+ * &"-,Bold Italic" code for "bold italic font style"
+ * &O - code for "outline style"
+ * &H - code for "shadow style"
+ * </code>
