-		    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.

-kses ChangeLog
-==============
-
-* 0.2.2 and 0.2.2-rc1
-
-0.2.2 was released on the 7th of February 2005. We also had a release
-candidate, 0.2.2-rc1, that was released on the 30th of January 2005.
-
-I (Ulf) am sorry for this long delay, but I lost interest in kses for a
-while and worked on auditing C/C++ code for buffer overflows and format
-string bugs in the Debian Security Audit Project instead
-( http://www.debian.org/security/audit/ ).
-
-This version has the following changes:
-
-- Richard contributed an additional object-oriented kses version for
-  PHP 5, which takes advantage of that PHP version's improved object
-  orientation. You can find it in the oop/ directory.
-
-- Richard added RemoveProtocol(), RemoveProtocols() and SetProtocols()
-  methods to both object-oriented kses versions. This closes SourceForge
-  bug #892477.
-
-- Richard also did other smaller changes to the object-oriented kses
-  versions. See oop/oop.kses.changelog.txt for the gory details.
-
-- The code that checks whether used elements and attributes are allowed
-  now uses isset() to avoid notices under certain configurations. This
-  hopefully closes SourceForge bug #918493.
-
-- The check for the Opera extra whitespace character #173 was moved so
-  it only affects attribute values and nothing else. This is helpful for
-  Asian kses users, who use that character in writing. (This is just a
-  temporary solution. A better one will show up in the next version, when
-  the parser is rewritten.) This closes SourceForge bug #834645, kind of.
-
-- Now the program will not even look at attributes and closing XHTML
-  slashes for closing HTML elements. This will make kses execute faster
-  and it won't accept atrocities like </br /> anymore.
-
-- Moved references in examples/test.php from function calls to the function
-  definition, making it better PHP.
-
-- The output of examples/test.php and examples/filter.php now conform fully
-  to W3C's HTML specification.
-
-- From now on, kses releases will be distributed both as .tar.gz and .zip
-  archives to please our Wintendo users. This closes SourceForge feature
-  request #900380.
-
-- Changed to new copyright year and paper mail address.
-
-
-* 0.2.1
-
-0.2.1 was released on the 29th of September 2003.
-It has the following changes:
-
-
-- There is now an additional version of kses, using the object-oriented
-  paradigm. Thanks a lot to Richard R. Vasquez, Jr., who created it! Anyone
-  who wants to make functional programming, logical programming or spaghetti
-  programming versions of kses as well (or any other programming paradigm that
-  you like), go ahead! All the people who like old procedural programming for
-  web applications shouldn't despair, though, as both versions will be
-  maintained with each release.
-
-- kses now has some new attribute value checks: minlen, minval and valueless.
-  See docs/attribute-value-checks for an explanation.
-
-- For some reason, the Opera developers decided to make chr(173) a whitespace
-  character in URL protocols, both when it occurs raw and in an entity. kses
-  now handles this.
-
-- The URL protocol whitelisting system now decodes entities before removing
-  NULLs and whitespaces.
-
-
-* 0.2.0
-
-0.2.0 was released on the 25th of July 2003.
-It has the following changes:
-
-
-- kses now supports checking of attribute values, and not just element names
-  and attribute names. The attribute value checks that exist so far are
-  'maxlen' (checks how long attribute values are, to avoid Buffer Overflows)
-  and 'maxval' (checks how big an integer value is, to avoid Denial of Service
-  attacks).
-
-  Buffer Overflows could both be a problem for WWW clients and different
-  servers on the Internet that an HTML document links to. One example is
-  <frame src="ftp://ftp.v1ct1m.com/AAAAAA..thousands_of_A's...">.
-
-  Denial of Service attacks can take the form of too big sizes of iframes or
-  other things. One example is <iframe src="http://some.web.server/"
-  width="20000" height="2000">, which makes some client machines completely
-  overloaded.
-
-- kses' old feature of removing "javascript:" from attribute values has been
-  improved. It now has a whole system for white listing of URL protocols, so
-  you can specify that it's acceptable with http:, https:, ftp: and gopher:,
-  but no other protocols in attribute values. The system tries pretty hard to
-  do the right thing with whitespace, upper/lower case, HTML entities
-  ("jav&#97;script:") and repeated entries ("javascript:javascript:alert(57)").
-
-- kses now supports both HTML and XHTML code, by allowing " /" at the end of
-  tags.
-
-- kses now removes Netscape 4's JavaScript entities, having the form
-  "&{alert(57)};". They don't even seem to work on all versions of Netscape 4,
-  but for completeness' sake it seemed like a good feature to add.
-
-- A bug with NULLs in javascript: URLs was fixed.
-  (Reported by Simon Cornelius P. Umacob - thanks!)
-
-- As a nice side effect of the white listing of URL protocols, kses now also
-  normalizes all HTML entities in documents. It will change HTML code with bad
-  entities to the right form, for example "AT&T" will be converted to
-  "AT&amp;T" and "<a href='lyrics.php?band=ladytron&lyrics=playgirl'>" will be
-  converted to "<a href='lyrics.php?band=ladytron&amp;lyrics=playgirl'>".
-  "&#000058;" will be converted to "&#58;", "&#XYZZY;" will be converted to
-  "&amp;#XYZZY;", "&auml!;" will be converted to "&amp;auml!;" and so on.
-
-  As shown above, it will process HTML entities that it doesn't understand.
-  It will also deal with too big numbers in numeric HTML entities, which is
-  helpful as many browsers seem to wrap them around at 2 ** 32, so the
-  characters 58, 58 + (2 ** 32), 58 + (2 ** 64) etcetera are all colons to the
-  web browser.
-
-- You can now use upper case letters in your $allowed_html array, in element
-  names, attribute names and attribute value check names. Version 0.1.0
-  required everything in that array to be in lower case, but that's not
-  necessary any more. You can also use upper case letters in
-  $allowed_protocols.
-
-- The "Really malformed thing" bug from the TODO file was fixed.
-  It used to convert this string:
-  x > 5 <a href="blah">
-  to:
-  x &gt; 5 &lt;a href=&quot;blah&quot;&gt;
-  and now it converts it to:
-  x &gt; 5 <a href="blah">
-
-- The "Weird malformed thing" bug from the TODO file was fixed.
-  It used to convert this string:
-  <a href="5 href=6>
-  to:
-  <a href="6">
-  because of the way kses restarts after a parse error in kses_hair(). Now it
-  converts it to:
-  <a>
-
-- A problem with slashes in HTML tags was fixed.
-
-- examples/filter.php used to use $SCRIPT_NAME, which doesn't work on
-  Windows.
-  (Reported by Simon Cornelius P. Umacob - thanks!)
-
-- kses now allows dashes in attribute names, for things like
-  <meta http-equiv=..>.
-
-
-* 0.1.0, first public version
-
-0.1.0 was released on the 9th of June 2003.
-It was announced on three security related mailing lists on Friday the 13th
-of June (nothing bad happened to it though).

-kses 0.2.2 README  [kses strips evil scripts!]
-=================
-
-
-* INTRODUCTION *
-
-
-Welcome to kses - an HTML/XHTML filter written in PHP. It removes all unwanted
-HTML elements and attributes, no matter how malformed HTML input you give it.
-It also does several checks on attribute values. kses can be used to avoid
-Cross-Site Scripting (XSS), Buffer Overflows and Denial of Service attacks,
-among other things.
-
-The program is released under the terms of the GNU General Public License. You
-should look into what that means, before using kses in your programs. You can
-find the full text of the license in the file COPYING.
-
-
-* FEATURES *
-
-
-Some of kses' current features are:
-
-* It will only allow the HTML elements and attributes that it was explicitly
-told to allow.
-
-* Element and attribute names are case-insensitive (a href vs A HREF).
-
-* It will understand and process whitespace correctly.
-
-* Attribute values can be surrounded with quotes, apostrophes or nothing.
-
-* It will accept valueless attributes with just names and no values (selected).
-
-* It will accept XHTML's closing " /" marks.
-
-* Attribute values that are surrounded with nothing will get quotes to avoid
-producing non-W3C conforming HTML
-(<a href=http://sourceforge.net/projects/kses> works but isn't valid HTML).
-
-* It handles lots of types of malformed HTML, by interpreting the existing
-code the best it can and then rebuilding new code from it. That's a better
-approach than trying to process existing code, as you're bound to forget about
-some weird special case somewhere. It handles problems like never-ending
-quotes and tags gracefully.
-
-* It will remove additional "<" and ">" characters that people may try to
-sneak in somewhere.
-
-* It supports checking attribute values for minimum/maximum length and
-minimum/maximum value, to protect against Buffer Overflows and Denial of
-Service attacks against WWW clients and various servers. You can stop
-<iframe src= width= height=> from having too high values for width and height,
-for instance.
-
-* It has got a system for whitelisting URL protocols. You can say that
-attribute values may only start with http:, https:, ftp: and gopher:, but no
-other URL protocols (javascript:, java:, about:, telnet:..). The functions that
-do this work handle whitespace, upper/lower case, HTML entities
-("jav&#97;script:") and repeated entries ("javascript:javascript:alert(57)").
-It also normalizes HTML entities as a nice side effect.
-
-* It removes Netscape 4's JavaScript entities ("&{alert(57)};").
-
-* It handles NULL bytes and Opera's chr(173) whitespace characters.
-
-* There is a procedural version and two object-oriented versions (for PHP 4
-  and PHP 5) of kses.
-
-
-* USE IT *
-
-
-It's very easy to use kses in your own PHP web application! Basic usage looks
-like this:
-
-
-<?php
-
-include 'kses.php';
-
-$allowed = array('b' => array(),
-                 'i' => array(),
-                 'a' => array('href' => 1, 'title' => 1),
-                 'p' => array('align' => 1),
-                 'br' => array());
-
-$val = $_POST['val'];
-if (get_magic_quotes_gpc())
-  $val = stripslashes($val);
-# You must strip slashes from magic quotes, or kses will get confused.
-
-$val = kses($val, $allowed); # The filtering takes place here.
-
-# Do something with $val.
-
-?>
-
-
-This definition of $allowed means that only the elements B, I, A, P and BR are
-allowed (along with their closing tags /B, /I, /A, /P and /BR). B, I and BR
-may not have any attributes. A may only have the attributes HREF and TITLE,
-while P may only have the attribute ALIGN. You can list the elements and
-attributes in the array in any mixture of upper and lower case. kses will also
-recognize HTML code that uses both lower and upper case.
-
-It's important to select the right allowed attributes, so you won't open up
-an XSS hole by mistake. Some important attributes that you mustn't allow
-include but are not limited to: 1) style, and 2) all intrinsic events
-attributes (onMouseOver and so on, on* really). I'll write more about this in
-the documentation that will be distributed with future versions of kses.
-
-It's also important to note that kses' HTML input must be cleaned of all
-slashes coming from magic quotes. If the rest of your code requires these
-slashes to be present, you can always add them again after calling kses with
-a simple addslashes() call.
-
-You should take a look at the documentation in the docs/ directory and the
-examples in the examples/ directory, to get more information on how to use
-kses. The object-oriented versions of kses are also worth checking out, and
-they're included in the oop/ directory.
-
-
-* UPGRADING TO 0.2.2 *
-
-
-kses 0.2.2 is backwards compatible with all previous releases, so upgrading
-should just be a matter of using a new version of kses.php instead of an old
-one.
-
-
-* NEW VERSIONS, MAILING LISTS AND BUG REPORTS *
-
-
-If you want to download new versions, subscribe to the kses-general mailing
-list or even take part in the development of kses, we refer you to its
-homepage at  http://sourceforge.net/projects/kses . New developers and beta
-testers are more than welcome!
-
-If you have any bug reports, suggestions for improvement or simply want to tell
-us that you use kses for some project, feel free to post to the kses-general
-mailing list. If you have found any security problems (particularly XSS,
-naturally) in kses, please contact Ulf privately at  metaur at users dot
-sourceforge dot net  so he can correct it before you or someone else tells the
-public about it.
-
-(No, it's not a security problem in kses if some program that uses it allows a
-bad attribute, silly. If kses is told to accept the element body with the
-attributes style and onLoad, it will accept them, even if that's a really bad
-idea, securitywise.)
-
-
-* OTHER HTML FILTERS *
-
-
-Here are the other stand-alone, open source HTML filters that we currently know
-of:
-
-* Htmlfilter for PHP - the filter from Squirrelmail
-  PHP
-  Konstantin Riabitsev
-  http://linux.duke.edu/projects/mini/htmlfilter/
-
-* HTML::StripScripts and related CPAN modules
-  Perl
-  Nick Cleaton
-  http://search.cpan.org/perldoc?HTML%3A%3AStripScripts
-
-* SafeHtmlChecker [is this really open source?]
-  PHP
-  Simon Willison
-  http://simon.incutio.com/archive/2003/02/23/safeHtmlChecker
-
-There are also a lot of HTML filters that were written specifically for some
-program. Some of them are better than others.
-
-Please write to the kses-general mailing list if you know of any other
-stand-alone, open-source filters.
-
-
-* DEDICATION *
-
-
-kses 0.2.2 is dedicated to Audrey Tautou and Jean-Pierre Jeunet.
-
-
-* MISC *
-
-
-The kses code is based on an HTML filter that Ulf wrote on his own back in 2002
-for the open-source project Gnuheter ( http://savannah.nongnu.org/projects/
-gnuheter ). Gnuheter is a fork from PHP-Nuke. The HTML filter has been
-improved a lot since then.
-
-To stop people from having sleepless nights, we feel the urgent need to state
-that kses doesn't have anything to do with the KDE project, despite having a
-name that starts with a K.
-
-In case someone was wondering, Ulf is available for kses-related consulting.
-
-Finally, the name kses comes from the terms XSS and access. It's also a
-recursive acronym (every open-source project should have one!) for "kses
-strips evil scripts".

-kses attribute value checks
-===========================
-
-As you've probably already read in the README file, an $allowed_html array
-normally looks like this:
-
-$allowed = array('b' => array(),
-                 'i' => array(),
-                 'a' => array('href' => 1,
-                              'title' => 1),
-                 'p' => array('align' => 1),
-                 'br' => array());
-
-This sets what elements and attributes are allowed.
-
-From kses 0.2.0, you can also perform some checks on the attribute values. You
-do it like this:
-
-$allowed = array('b' => array(),
-                 'i' => array(),
-                 'a' => array('href' =>

-                                array('maxval' => 20)),
-                 'br' => array());
-
-This means that kses should perform the maxlen check with the value 100 on the
-<a href=> value, as well as the maxval check with the value 20 on the <font
-size=> value.
-
-The currently implemented checks (with more to come) are 'maxlen', 'maxval',
-'minlen', 'minval' and 'valueless'.
-
-'maxlen' checks that the length of the attribute value is not greater than the
-given value. It is helpful against Buffer Overflows in WWW clients and various
-servers on the Internet. In my example above, it would mean that
-"<a href='ftp://ftp.v1ct1m.com/AAAA..thousands_of_A's...'>" wouldn't be
-accepted.
-
-Of course, this problem is even worse if you put that long URL in a <frame>
-tag instead, so the WWW client will fetch it automatically without a user
-having to click it.
-
-'maxval' checks that the attribute value is an integer greater than or equal to
-zero, that it doesn't have an unreasonable amount of zeroes or whitespace (to
-avoid Buffer Overflows), and that it is not greater than the given value. In
-my example above, it would mean that "<font size='20'>" is accepted but
-"<font size='21'>" is not. This check helps against Denial of Service attacks
-against WWW clients.
-
-One example of this DoS problem is <iframe src="http://some.web.server/"
-width="20000" height="2000">, which makes some client machines completely
-overloaded.
-
-'minlen' and 'minval' works the same as 'maxlen' and 'maxval', except that they
-check for minimum lengths and values instead of maximum ones.
-
-'valueless' checks if an attribute has a value (like <a href="blah">) or not
-(<option selected>). If the given value is a "y" or a "Y", the attribute must
-not have a value to be accepted. If the given value is an "n" or an "N", the
-attribute must have a value. Note that <a href=""> is considered to have a
-value, so there's a difference between valueless attributes and attribute
-values with the length zero.
-
-You can combine more than one check, by putting one after the other in the
-inner array.

-kses hooks
-==========
-
-Sometimes you want to perform one more action on all data that kses will
-filter. There is a special function for that purpose called kses_hook(). kses
-calls it from its main function kses(), so if you insert some code in
-kses_hook(), it will always be called to change all data that kses sees.

-=========================
-
-Sometimes you want to use kses for stripping all (X)HTML tags from a document.
-You do it by calling kses like this:

-kses supported formats
-======================

-It should be noted that kses doesn't deal with any smiley plus newline plus
-HTML format. It uses HTML or XHTML, both as input and as output.
-Conversions from the preferred format to or from HTML or XHTML is up to you.

-kses whitelisted URL protocols
-==============================
-
-From kses 0.2.0, it has a function that checks all attribute values for URL
-protocols and only allows the protocols given in a whitelist.
-
-If you call kses the old way with two parameters - a string and an
-$allowed_html array - it will take its own default array, which whitelists the
-protocols http, https, ftp, news, nntp, telnet, gopher and mailto. Pretty
-reasonable, but anyone who wants to change it just calls the kses() function
-with a third parameter, like this:
-
-$string = kses($string, $allowed_html, array('http', 'https'));
-
-Note that you shouldn't include any colon after http or other protocol names.

-	
-	- Deprecated _hook(), Protocols()
-	
-	- Added AddProtocols() to replace Protocols()
-	
-	- Added filterKsesTextHook() to replace _hook()
-	
-	- Added RemoveProtocol() and RemoveProtocols() to remove protocols singly,
-	  or batch.  This should clear bug #892477

-OOP
-	- Forked code into PHP4 and PHP5 versions.  Use '$myKses = new kses[45]'
-	  from now on.
-	
-	- Modified code to run in E_STRICT.  This should clear bug #918493

-
-	- Started CVSing the code.
-
-OOP
-	* 0.0.1
-	- Turned all the kses_function_name functions to _function_name methods.
-
-	- Added a couple of properties (allowed_protocols, allowed_html) with
-	  $this->allowed_protocols defaulting to the lion's share of usual
-	  protocols.
-
-	- Modified the applicable use of preg_replace() functions to point to
-	  internal class methods.
-
-	- Reduced the parameter list of some methods since internal properties
-	  are now being used.
-
-	- Added "public" methods to set up the allowed protocols and HTML.
-
-Procedural
-	* 0.2.1
-
-	0.2.1 was released on the 29th of September 2003.
-	It has the following changes:
-
-	- There is now an additional version of kses, using the object-oriented
-	  paradigm. Thanks a lot to Richard R. Vasquez, Jr., who created it!
-	  Anyone who wants to make functional programming, logical programming or
-	  spaghetti programming versions of kses as well (or any other programming
-	  paradigm that you like), go ahead! All the people who like old
-	  procedural programming for web applications shouldn't despair, though,
-	  as both versions will be maintained with each release.
-
-	- kses now has some new attribute value checks: minlen, minval and
-	  valueless.  See docs/attribute-value-checks for an explanation.
-
-	- For some reason, the Opera developers decided to make chr(173) a
-	  whitespace character in URL protocols, both when it occurs raw and in an
-	  entity. kses now handles this.
-
-	- The URL protocol whitelisting system now decodes entities before
-	  removing NULLs and whitespaces.
-
-Procedural
-	* 0.2.0
-
-	0.2.0 was released on the 25th of July 2003.
-	It has the following changes:
-
-	- kses now supports checking of attribute values, and not just element
-	  names and attribute names. The attribute value checks that exist so far
-	  are 'maxlen' (checks how long attribute values are, to avoid Buffer
-	  Overflows) and 'maxval' (checks how big an integer value is, to avoid
-	  Denial of Service attacks).
-
-	  Buffer Overflows could both be a problem for WWW clients and different
-	  servers on the Internet that an HTML document links to. One example is
-	  <frame src="ftp://ftp.v1ct1m.com/AAAAAA..thousands_of_A's...">.
-
-	  Denial of Service attacks can take the form of too big sizes of iframes
-	  or other things. One example is <iframe src="http://some.web.server/"
-	  width="20000" height="2000">, which makes some client machines
-	  completely overloaded.
-
-	- kses' old feature of removing "javascript:" from attribute values has
-	  been improved. It now has a whole system for white listing of URL
-	  protocols, so you can specify that it's acceptable with http:, https:,
-	  ftp: and gopher:, but no other protocols in attribute values. The system
-	  tries pretty hard to do the right thing with whitespace, upper/lower
-	  case, HTML entities ("jav&#97;script:") and repeated entries
-	  ("javascript:javascript:alert(57)").
-
-	- kses now supports both HTML and XHTML code, by allowing " /" at the end
-	  of tags.
-
-	- kses now removes Netscape 4's JavaScript entities, having the form
-	  "&{alert(57)};". They don't even seem to work on all versions of
-	  Netscape 4, but for completeness' sake it seemed like a good feature to
-	  add.
-
-	- A bug with NULLs in javascript: URLs was fixed.
-	  (Reported by Simon Cornelius P. Umacob - thanks!)
-
-	- As a nice side effect of the white listing of URL protocols, kses now
-	  also normalizes all HTML entities in documents. It will change HTML code
-	  with bad entities to the right form, for example "AT&T" will be
-	  converted to "AT&amp;T" and "<a href='lyrics.php?band=ladytron&lyrics=
-	  playgirl'>" will be converted to "<a href='lyrics.php?band=
-	  ladytron&amp;lyrics=playgirl'>". "&#000058;" will be converted to
-	  "&#58;", "&#XYZZY;" will be converted to "&amp;#XYZZY;", "&auml!;" will
-	  be converted to "&amp;auml!;" and so on.
-
-	  As shown above, it will process HTML entities that it doesn't
-	  understand.  It will also deal with too big numbers in numeric HTML
-	  entities, which is helpful as many browsers seem to wrap them around at
-	  2 ** 32, so the characters 58, 58 + (2 ** 32), 58 + (2 ** 64) etcetera
-	  are all colons to the web browser.
-
-	- You can now use upper case letters in your $allowed_html array, in
-	  element names, attribute names and attribute value check names. Version
-	  0.1.0 required everything in that array to be in lower case, but that's
-	  not necessary any more. You can also use upper case letters in
-	  $allowed_protocols.
-
-	- The "Really malformed thing" bug from the TODO file was fixed.
-	  It used to convert this string:
-	  x > 5 <a href="blah">
-	  to:
-	  x &gt; 5 &lt;a href=&quot;blah&quot;&gt;
-	  and now it converts it to:
-	  x &gt; 5 <a href="blah">
-
-	- The "Weird malformed thing" bug from the TODO file was fixed.
-	  It used to convert this string:
-	  <a href="5 href=6>
-	  to:
-	  <a href="6">
-	  because of the way kses restarts after a parse error in kses_hair().
-	  Now it converts it to:
-	  <a>
-
-	- A problem with slashes in HTML tags was fixed.
-
-	- examples/filter.php used to use $SCRIPT_NAME, which doesn't work on
-	  Windows.
-	  (Reported by Simon Cornelius P. Umacob - thanks!)
-
-	- kses now allows dashes in attribute names, for things like
-	  <meta http-equiv=..>.

-	0.1.0 was released on the 9th of June 2003.
-	It was announced on three security related mailing lists on Friday the

-Parse($string = "")
-	The basic function of kses.  Give it a $string, and it will strip
-	out the unwanted HTML and attributes.
-
-AddProtocols()
-	Add a protocol or list of protocols to the kses object to be
-	considered valid during a Parse().  The parameter can be a string
-	containing a single protocol, or an array of strings, each
-	containing a single protocol.
-
-Protocols()
-	Deprecated.  Use AddProtocols()
-
-AddProtocol($protocol = "")
-	Adds a single protocol to the kses object that will be considered
-	valid during a Parse().
-
-SetProtocols()
-	This is a straight setting/overwrite of existing protocols in the
-	kses object.  All existing protocols are removed, and the parameter
-	is used to determine what protocol(s) the kses object will consider
-	valid.  The parameter can be a string containing a single protocol,
-	or an array of strings, each constaining a single protocol.
-
-DumpProtocols()
-	This returns an indexed array of the valid protocols contained in
-	the kses object.
-
-DumpElements()
-	This returns an associative array of the valid (X)HTML elements in
-	the kses object along with attributes for each element, and tests
-	that will be performed on each attribute.
-
-AddHTML($tag = "", $attribs = array())
-	This allows the end user to add a single (X)HTML element to the
-	kses object along with the (if any) attributes that the specific
-	(X)HTML element is allowed to have.
-	
-	See the file 'attribute-value-checks' for more information as to
-	the format of the data to be provided to this method.
-
-RemoveProtocol($protocol = "")
-	This allows for the removal of a single protocol from the list of
-	valid protocols in the kses object.
-
-RemoveProtocols()
-	This allows for the single or batch removal of protocols from the
-	kses object.  The parameter is either a string containing a
-	protocol to be removed, or an array of strings that each contain
-	a protocol.
-
-filterKsesTextHook($string)
-	For the OOP version of kses, this is an additional hook that allows
-	the end user to perform additional postprocessing of a string
-	that's being run through Parse().
-
-_hook()
-	Deprecated.  Use filterKsesTextHook().

-	*	maintains backward compatibility syntax-wise, the version number is now 1.0.0.  Any
-	*	minor changes that do not break compatibility will be indicated in the second or third
-	*	digits.  Anything that breaks compatibility will change the major version number.
-	*
-	*	PHP5 specific changes:
-	*	+ Private methods are now in place
-	*	+ __construct() is now used rather then the standard class name 'kses()'
-	*	+ Kses will not load in any version less that PHP5
-	*	Other modifications:
-	*	+ PHPdoc style documentation has been added to the class.  See http://www.phpdoc.org/ for more info.
-	*	+ Method names have been changed to reflect status as verbs
-	*	+ One line methods have been folded into the code
-	*	+ Some methods are now deprecated due to nomenclature style change.  See method documentation for specifics.
-	*	+ Kses5 now works in E_STRICT
-	*	+ Version number is 1.0.0 to reflect serious code changes
-	*	+ Addition of methods AddProtocols(), filterKsestextHook(), RemoveProtocol(), RemoveProtocols() and SetProtocols()
