+            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

+             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.

+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.

+Requirements
+===========================================================================
+
+* PHP 4.2.0 (or higher) for getID3() 1.7.x (and earlier)
+* PHP 5.3.0 (or higher) for getID3() 1.8.x (and up)
+* PHP 5.0.0 (or higher) for getID3() 2.0.x (and up)
+* at least 4MB memory for PHP. 8MB is highly recommended.
+  12MB is required with all modules loaded.
+
+
+
+Usage
+===========================================================================
+
+See /demos/demo.basic.php for a very basic use of getID3() with no
+fancy output, just scanning one file.
+
+See structure.txt for the returned data structure.
+
+*>  For an example of a complete directory-browsing,       <*
+*>  file-scanning implementation of getID3(), please run   <*
+*>  /demos/demo.browse.php                                 <*
+
+See /demos/demo.mysql.php for a sample recursive scanning code that
+scans every file in a given directory, and all sub-directories, stores
+the results in a database and allows various analysis / maintenance
+operations
+
+To analyze remote files over HTTP or FTP you need to copy the file
+locally first before running getID3(). Your code would look something
+like this:
+
+// Copy remote file locally to scan with getID3()
+$remotefilename = 'http://www.example.com/filename.mp3';
+if ($fp_remote = fopen($remotefilename, 'rb')) {
+    $localtempfilename = tempnam('/tmp', 'getID3');
+    if ($fp_local = fopen($localtempfilename, 'wb')) {
+        while ($buffer = fread($fp_remote, 8192)) {
+            fwrite($fp_local, $buffer);
+        }
+        fclose($fp_local);
+
+		// Initialize getID3 engine
+		$getID3 = new getID3;
+
+		$ThisFileInfo = $getID3->analyze($filename);
+
+        // Delete temporary file
+        unlink($localtempfilename);
+    }
+    fclose($fp_remote);
+}
+
+
+See /demos/demo.write.php for how to write tags.
+
+
+
+What does the returned data structure look like?
+===========================================================================
+
+See structure.txt
+
+It is recommended that you look at the output of
+/demos/demo.browse.php scanning the file(s) you're interested in to
+confirm what data is actually returned for any particular filetype in
+general, and your files in particular, as the actual data returned
+may vary considerably depending on what information is available in
+the file itself.
+
+
+
+Notes
+===========================================================================
+
+getID3() 1.x:
+If the format parser encounters a critical problem, it will return
+something in $fileinfo['error'], describing the encountered error. If
+a less critical error or notice is generated it will appear in
+$fileinfo['warning']. Both keys may contain more than one warning or
+error. If something is returned in ['error'] then the file was not
+correctly parsed and returned data may or may not be correct and/or
+complete. If something is returned in ['warning'] (and not ['error'])
+then the data that is returned is OK - usually getID3() is reporting
+errors in the file that have been worked around due to known bugs in
+other programs. Some warnings may indicate that the data that is
+returned is OK but that some data could not be extracted due to
+errors in the file.
+
+getID3() 2.x:
+See above except errors are thrown (so you will only get one error).
+
+
+
+Disclaimer
+===========================================================================
+
+getID3() has been tested on many systems, on many types of files,
+under many operating systems, and is generally believe to be stable
+and safe. That being said, there is still the chance there is an
+undiscovered and/or unfixed bug that may potentially corrupt your
+file, especially within the writing functions. By using getID3() you
+agree that it's not my fault if any of your files are corrupted.
+In fact, I'm not liable for anything :)

+
+FAQ:
+Q: Can I use getID3() in my program? Do I need a commercial license?
+A: You're generally free to use getID3 however you see fit. The only
+   case in which you would require a commercial license is if you're
+   selling your closed-source program that integrates getID3. If you
+   sell your program including a copy of getID3, that's fine as long
+   as you include a copy of the sourcecode when you sell it.  Or you
+   can distribute your code without getID3 and say "download it from
+   getid3.sourceforge.net"
+
+
+
+Why is it called "getID3()" if it does so much more than just that?
+===========================================================================
+
+v0.1 did in fact just do that. I don't have a copy of code that old, but I
+could essentially write it today with a one-line function:
+  function getID3($filename) { return unpack('a3TAG/a30title/a30artist/a30album/a4year/a28comment/c1track/c1genreid', substr(file_get_contents($filename), -128)); }
+

+
+Known Bugs/Issues in getID3() that may be fixed eventually
+===========================================================================
+http://www.getid3.org/phpBB3/viewtopic.php?t=25
+
+* Cannot determine bitrate for MPEG video with VBR video data
+  (need documentation)
+* Interlace/progressive cannot be determined for MPEG video
+  (need documentation)
+* MIDI playtime is sometimes inaccurate
+* AAC-RAW mode files cannot be identified
+* WavPack-RAW mode files cannot be identified
+* mp4 files report lots of "Unknown QuickTime atom type"
+   (need documentation)
+* Encrypted ASF/WMA/WMV files warn about "unhandled GUID
+  ASF_Content_Encryption_Object"
+* Bitrate split between audio and video cannot be calculated for
+  NSV, only the total bitrate. (need documentation)
+* All Ogg formats (Vorbis, OggFLAC, Speex) are affected by the
+  problem of large VorbisComments spanning multiple Ogg pages, but
+  but only OggVorbis files can be processed with vorbiscomment.
+* The version of "head" supplied with Mac OS 10.2.8 (maybe other
+  versions too) does only understands a single option (-n) and
+  therefore fails. getID3 ignores this and returns wrong md5_data.
+
+
+
+Known Bugs/Issues in getID3() that cannot be fixed
+--------------------------------------------------
+http://www.getid3.org/phpBB3/viewtopic.php?t=25
+
+* 32-bit PHP installations only:
+  Files larger than 2GB cannot always be parsed fully by getID3()
+  due to limitations in the 32-bit PHP filesystem functions.
+  NOTE: Since v1.7.8b3 there is partial support for larger-than-
+  2GB files, most of which will parse OK, as long as no critical
+  data is located beyond the 2GB offset.
+  Known will-work:
+  * all file formats on 64-bit PHP
+  * ZIP  (format doesn't support files >2GB)
+  * FLAC (current encoders don't support files >2GB)
+  Known will-not-work:
+  * ID3v1 tags (always located at end-of-file)
+  * Lyrics3 tags (always located at end-of-file)
+  * APE tags (always located at end-of-file)
+  Maybe-will-work:
+  * Quicktime (will work if needed metadata is before 2GB offset,
+    that is if the file has been hinted/optimized for streaming)
+  * RIFF.WAV (should work fine, but gives warnings about not being
+    able to parse all chunks)
+  * RIFF.AVI (playtime will probably be wrong, is only based on
+    "movi" chunk that fits in the first 2GB, should issue error
+    to show that playtime is incorrect. Other data should be mostly
+    correct, assuming that data is constant throughout the file)
+
+
+
+Known Bugs/Issues in other programs
+-----------------------------------
+http://www.getid3.org/phpBB3/viewtopic.php?t=25
+
+* Windows Media Player (up to v11) and iTunes (up to v10+) do
+    not correctly handle ID3v2.3 tags with UTF-16BE+BOM
+    encoding (they assume the data is UTF-16LE+BOM and either
+    crash (WMP) or output Asian character set (iTunes)
+* Winamp (up to v2.80 at least) does not support ID3v2.4 tags,
+    only ID3v2.3
+    see: http://forums.winamp.com/showthread.php?postid=387524
+* Some versions of Helium2 (www.helium2.com) do not write
+    ID3v2.4-compliant Frame Sizes, even though the tag is marked
+    as ID3v2.4)  (detected by getID3())
+* MP3ext V3.3.17 places a non-compliant padding string at the end
+    of the ID3v2 header. This is supposedly fixed in v3.4b21 but
+    only if you manually add a registry key. This fix is not yet
+    confirmed.  (detected by getID3())
+* CDex v1.40 (fixed by v1.50b7) writes non-compliant Ogg comment
+    strings, supposed to be in the format "NAME=value" but actually
+    written just "value"  (detected by getID3())
+* Oggenc 0.9-rc3 flags the encoded file as ABR whether it's
+    actually ABR or VBR.
+* iTunes (versions "X v2.0.3", "v3.0.1" are known-guilty, probably
+    other versions are too) writes ID3v2.3 comment tags using a
+    frame name 'COM ' which is not valid for ID3v2.3+ (it's an
+    ID3v2.2-style frame name)  (detected by getID3())
+* MP2enc does not encode mono CBR MP2 files properly (half speed
+    sound and double playtime)
+* MP2enc does not encode mono VBR MP2 files properly (actually
+    encoded as stereo)
+* tooLAME does not encode mono VBR MP2 files properly (actually
+    encoded as stereo)
+* AACenc encodes files in VBR mode (actually ABR) even if CBR is
+   specified
+* AAC/ADIF - bitrate_mode = cbr for vbr files
+* LAME 3.90-3.92 prepends one frame of null data (space for the
+  LAME/VBR header, but it never gets written) when encoding in CBR
+  mode with the DLL
+* Ahead Nero encodes TwinVQF with a DSIZ value (which is supposed
+  to be the filesize in bytes) of "0" for TwinVQF v1.0 and "1" for
+  TwinVQF v2.0  (detected by getID3())
+* Ahead Nero encodes TwinVQF files 1 second shorter than they
+  should be
+* AAC-ADTS files are always actually encoded VBR, even if CBR mode
+  is specified (the CBR-mode switches on the encoder enable ABR
+  mode, not CBR as such, but it's not possible to tell the
+  difference between such ABR files and true VBR)
+* STREAMINFO.audio_signature in OggFLAC is always null. "The reason
+  it's like that is because there is no seeking support in
+  libOggFLAC yet, so it has no way to go back and write the
+  computed sum after encoding. Seeking support in Ogg FLAC is the
+  #1 item for the next release." - Josh Coalson (FLAC developer)
+  NOTE: getID3() will calculate md5_data in a method similar to
+  other file formats, but that value cannot be compared to the
+  md5_data value from FLAC data in a FLAC file format.
+* STREAMINFO.audio_signature is not calculated in FLAC v0.3.0 &
+  v0.4.0 - getID3() will calculate md5_data in a method similar to
+  other file formats, but that value cannot be compared to the
+  md5_data value from FLAC v0.5.0+
+* RioPort (various versions including 2.0 and 3.11) tags ID3v2 with
+  a WCOM frame that has no data portion
+* Earlier versions of Coolplayer adds illegal ID3 tags to Ogg Vorbis
+  files, thus making them corrupt.
+* Meracl ID3 Tag Writer v1.3.4 (and older) incorrectly truncates the
+  last byte of data from an MP3 file when appending a new ID3v1 tag.
+  (detected by getID3())
+* Lossless-Audio files encoded with and without the -noseek switch
+  do actually differ internally and therefore cannot match md5_data
+* iTunes has been known to append a new ID3v1 tag on the end of an
+  existing ID3v1 tag when ID3v2 tag is also present
+  (detected by getID3())
+* MediaMonkey may write a blank RGAD ID3v2 frame but put actual
+  replay gain adjustments in a series of user-defined TXXX frames
+  (detected and handled by getID3() since v1.9.2)
+
