      Please read this License carefully before downloading this software.  By
      downloading or using this software, you are agreeing to be bound by the terms of
      this License.  If you do not or cannot agree to the terms of this License,

      Apple Note:  In January 2007, Apple changed its corporate name from "Apple
      Computer, Inc." to "Apple Inc."  This change has been reflected below and
      copyright years updated, but no other changes have been made to the APSL 2.0.

      1.      General; Definitions.  This License applies to any program or other work
      which Apple Inc. ("Apple") makes publicly available and which contains a notice
      placed by Apple identifying such program or work as "Original Code" and stating
      that it is subject to the terms of this Apple Public Source License version 2.0
      ("License").  As used in this License:

      1.1      "Applicable Patent Rights" mean:  (a) in the case where Apple is the
      grantor of rights, (i) claims of patents that are now or hereafter acquired,
      owned by or assigned to Apple and (ii) that cover subject matter contained in
      the Original Code, but only to the extent necessary to use, reproduce and/or
      distribute the Original Code without infringement; and (b) in the case where You
      are the grantor of rights, (i) claims of patents that are now or hereafter
      acquired, owned by or assigned to You and (ii) that cover subject matter in Your
      Modifications, taken alone or in combination with Original Code.

      1.2     "Contributor" means any person or entity that creates or contributes to the
      creation of Modifications.

      1.3      "Covered Code" means the Original Code, Modifications, the combination of
      Original Code and any Modifications, and/or any respective portions thereof.

      1.4     "Externally Deploy" means: (a) to sublicense, distribute or otherwise make
      Covered Code available, directly or indirectly, to anyone other than You; and/or
      (b) to use Covered Code, alone or as part of a Larger Work, in any way to
      provide a service, including but not limited to delivery of content, through
      electronic communication with a client other than You.

      1.5     "Larger Work" means a work which combines Covered Code or portions thereof
      with code not governed by the terms of this License.

      1.6     "Modifications" mean any addition to, deletion from, and/or change to, the
      substance and/or structure of the Original Code, any previous Modifications, the
      combination of Original Code and any previous Modifications, and/or any
      respective portions thereof.  When code is released as a series of files, a
      Modification is:  (a) any addition to or deletion from the contents of a file
      containing Covered Code; and/or (b) any new file or other representation of
      computer program statements that contains any part of Covered Code.

      1.7     "Original Code" means (a) the Source Code of a program or other work as
      originally made available by Apple under this License, including the Source Code
      of any updates or upgrades to such programs or works made available by Apple
      under this License, and that has been expressly identified by Apple as such in
      the header file(s) of such work; and (b) the object code compiled from such
      Source Code and originally made available by Apple under this License

      1.8     "Source Code" means the human readable form of a program or other work that
      is suitable for making modifications to it, including all modules it contains,
      plus any associated interface definition files, scripts used to control
      compilation and installation of an executable (object code).

      1.9     "You" or "Your" means an individual or a legal entity exercising rights
      under this License.  For legal entities, "You" or "Your" includes any entity
      which controls, is controlled by, or is under common control with, You, where
      "control" means (a) the power, direct or indirect, to cause the direction or
      management of such entity, whether by contract or otherwise, or (b) ownership of
      fifty percent (50%) or more of the outstanding shares or beneficial ownership of
      such entity.

      2.      Permitted Uses; Conditions &amp; Restrictions.   Subject to the terms and
      conditions of this License, Apple hereby grants You, effective on the date You
      accept this License and download the Original Code, a world-wide, royalty-free,
      non-exclusive license, to the extent of Apple's Applicable Patent Rights and
      copyrights covering the Original Code, to do the following:

      2.1     Unmodified Code.  You may use, reproduce, display, perform, internally
      distribute within Your organization, and Externally Deploy verbatim, unmodified
      copies of the Original Code, for commercial or non-commercial purposes, provided
      that in each instance:

      (a)     You must retain and reproduce in all copies of Original Code the copyright
      and other proprietary notices and disclaimers of Apple as they appear in the
      Original Code, and keep intact all notices in the Original Code that refer to
      this License; and

      (b)     You must include a copy of this License with every copy of Source Code of
      Covered Code and documentation You distribute or Externally Deploy, and You may
      not offer or impose any terms on such Source Code that alter or restrict this
      License or the recipients' rights hereunder, except as permitted under Section
      6.

      2.2     Modified Code.  You may modify Covered Code and use, reproduce, display,
      perform, internally distribute within Your organization, and Externally Deploy
      Your Modifications and Covered Code, for commercial or non-commercial purposes,
      provided that in each instance You also meet all of these conditions:

      (a)     You must satisfy all the conditions of Section 2.1 with respect to the
      Source Code of the Covered Code;

      (b)     You must duplicate, to the extent it does not already exist, the notice in
      Exhibit A in each file of the Source Code of all Your Modifications, and cause
      the modified files to carry prominent notices stating that You changed the files
      and the date of any change; and

      (c)     If You Externally Deploy Your Modifications, You must make Source Code of
      all Your Externally Deployed Modifications either available to those to whom You
      have Externally Deployed Your Modifications, or publicly available.  Source Code
      of Your Externally Deployed Modifications must be released under the terms set
      forth in this License, including the license grants set forth in Section 3
      below, for as long as you Externally Deploy the Covered Code or twelve (12)
      months from the date of initial External Deployment, whichever is longer. You
      should preferably distribute the Source Code of Your Externally Deployed
      Modifications electronically (e.g. download from a web site).

      2.3     Distribution of Executable Versions.  In addition, if You Externally Deploy
      Covered Code (Original Code and/or Modifications) in object code, executable
      form only, You must include a prominent notice, in the code itself as well as in
      related documentation, stating that Source Code of the Covered Code is available
      under the terms of this License with information on how and where to obtain such
      Source Code.

      2.4     Third Party Rights.  You expressly acknowledge and agree that although
      Apple and each Contributor grants the licenses to their respective portions of
      the Covered Code set forth herein, no assurances are provided by Apple or any
      Contributor that the Covered Code does not infringe the patent or other
      intellectual property rights of any other entity. Apple and each Contributor
      disclaim any liability to You for claims brought by any other entity based on
      infringement of intellectual property rights or otherwise. As a condition to
      exercising the rights and licenses granted hereunder, You hereby assume sole
      responsibility to secure any other intellectual property rights needed, if any.
      For example, if a third party patent license is required to allow You to
      distribute the Covered Code, it is Your responsibility to acquire that license
      before distributing the Covered Code.

      3.      Your Grants.  In consideration of, and as a condition to, the licenses
      granted to You under this License, You hereby grant to any person or entity
      receiving or distributing Covered Code under this License a non-exclusive,
      royalty-free, perpetual, irrevocable license, under Your Applicable Patent
      Rights and other intellectual property rights (other than patent) owned or
      controlled by You, to use, reproduce, display, perform, modify, sublicense,
      distribute and Externally Deploy Your Modifications of the same scope and extent
      as Apple's licenses under Sections 2.1 and 2.2 above.

      4.      Larger Works.  You may create a Larger Work by combining Covered Code with
      other code not governed by the terms of this License and distribute the Larger
      Work as a single product.  In each such instance, You must make sure the
      requirements of this License are fulfilled for the Covered Code or any portion
      thereof.

      5.      Limitations on Patent License.   Except as expressly stated in Section 2, no
      other patent rights, express or implied, are granted by Apple herein.
      Modifications and/or Larger Works may require additional patent licenses from
      Apple which Apple may grant in its sole discretion.

      6.      Additional Terms.  You may choose to offer, and to charge a fee for,
      warranty, support, indemnity or liability obligations and/or other rights
      consistent with the scope of the license granted herein ("Additional Terms") to
      one or more recipients of Covered Code. However, You may do so only on Your own
      behalf and as Your sole responsibility, and not on behalf of Apple or any
      Contributor. You must obtain the recipient's agreement that any such Additional
      Terms are offered by You alone, and You hereby agree to indemnify, defend and
      hold Apple and every Contributor harmless for any liability incurred by or
      claims asserted against Apple or such Contributor by reason of any such
      Additional Terms.

      7.      Versions of the License.  Apple may publish revised and/or new versions of
      this License from time to time.  Each version will be given a distinguishing
      version number.  Once Original Code has been published under a particular
      version of this License, You may continue to use it under the terms of that
      version. You may also choose to use such Original Code under the terms of any
      subsequent version of this License published by Apple.  No one other than Apple
      has the right to modify the terms applicable to Covered Code created under this
      License.

      8.      NO WARRANTY OR SUPPORT.  The Covered Code may contain in whole or in part
      pre-release, untested, or not fully tested works.  The Covered Code may contain
      errors that could cause failures or loss of data, and may be incomplete or
      contain inaccuracies.  You expressly acknowledge and agree that use of the
      Covered Code, or any portion thereof, is at Your sole and entire risk.  THE
      COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR SUPPORT OF
      ANY KIND AND APPLE AND APPLE'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS "APPLE"
      FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY DISCLAIM
      ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED
      TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF SATISFACTORY
      QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF QUIET ENJOYMENT,
      AND NONINFRINGEMENT OF THIRD PARTY RIGHTS.  APPLE AND EACH CONTRIBUTOR DOES NOT
      WARRANT AGAINST INTERFERENCE WITH YOUR ENJOYMENT OF THE COVERED CODE, THAT THE
      FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR REQUIREMENTS, THAT THE
      OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT
      DEFECTS IN THE COVERED CODE WILL BE CORRECTED.  NO ORAL OR WRITTEN INFORMATION
      OR ADVICE GIVEN BY APPLE, AN APPLE AUTHORIZED REPRESENTATIVE OR ANY CONTRIBUTOR
      SHALL CREATE A WARRANTY.  You acknowledge that the Covered Code is not intended
      for use in the operation of nuclear facilities, aircraft navigation,
      communication systems, or air traffic control machines in which case the failure
      of the Covered Code could lead to death, personal injury, or severe physical or
      environmental damage.

      9.      LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT
      SHALL APPLE OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT
      OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR YOUR USE
      OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF, WHETHER UNDER A
      THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY OR
      OTHERWISE, EVEN IF APPLE OR SUCH CONTRIBUTOR HAS BEEN ADVISED OF THE POSSIBILITY
      OF SUCH DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY
      REMEDY. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY OF
      INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU. In
      no event shall Apple's total liability to You for all damages (other than as may
      be required by applicable law) under this License exceed the amount of fifty
      dollars ($50.00).

      10.     Trademarks.  This License does not grant any rights to use the trademarks
      or trade names  "Apple", "Mac", "Mac OS", "QuickTime", "QuickTime Streaming
      Server" or any other trademarks, service marks, logos or trade names belonging
      to Apple (collectively "Apple Marks") or to any trademark, service mark, logo or
      trade name belonging to any Contributor.  You agree not to use any Apple Marks
      in or as part of the name of products derived from the Original Code or to
      endorse or promote products derived from the Original Code other than as
      expressly permitted by and in strict compliance at all times with Apple's third
      party trademark usage guidelines which are posted at
      http://www.apple.com/legal/guidelinesfor3rdparties.html.

      11.     Ownership. Subject to the licenses granted under this License, each
      Contributor retains all rights, title and interest in and to any Modifications
      made by such Contributor.  Apple retains all rights, title and interest in and
      to the Original Code and any Modifications made by or on behalf of Apple ("Apple
      Modifications"), and such Apple Modifications will not be automatically subject
      to this License.  Apple may, at its sole discretion, choose to license such
      Apple Modifications under this License, or on different terms from those
      contained in this License or may choose not to license them at all.

      12.     Termination.

      12.1    Termination.  This License and the rights granted hereunder will
      terminate:

      (a)     automatically without notice from Apple if You fail to comply with any
      term(s) of this License and fail to cure such breach within 30 days of becoming
      aware of such breach; (b)       immediately in the event of the circumstances
      described in Section 13.5(b); or (c)    automatically without notice from Apple if
      You, at any time during the term of this License, commence an action for patent
      infringement against Apple; provided that Apple did not first commence an action
      for patent infringement against You in that instance.

      12.2    Effect of Termination.  Upon termination, You agree to immediately stop
      any further use, reproduction, modification, sublicensing and distribution of
      the Covered Code.  All sublicenses to the Covered Code which have been properly
      granted prior to termination shall survive any termination of this License.
      Provisions which, by their nature, should remain in effect beyond the
      termination of this License shall survive, including but not limited to Sections
      3, 5, 8, 9, 10, 11, 12.2 and 13.  No party will be liable to any other for
      compensation, indemnity or damages of any sort solely as a result of terminating
      this License in accordance with its terms, and termination of this License will
      be without prejudice to any other right or remedy of any party.

      13.     Miscellaneous.

      13.1    Government End Users.   The Covered Code is a "commercial item" as defined
      in FAR 2.101.  Government software and technical data rights in the Covered Code
      include only those rights customarily provided to the public as defined in this
      License. This customary commercial license in technical data and software is
      provided in accordance with FAR 12.211 (Technical Data) and 12.212 (Computer
      Software) and, for Department of Defense purchases, DFAR 252.227-7015 (Technical
      Data -- Commercial Items) and 227.7202-3 (Rights in Commercial Computer Software
      or Computer Software Documentation).  Accordingly, all U.S. Government End Users
      acquire Covered Code with only those rights set forth herein.

      13.2    Relationship of Parties.  This License will not be construed as creating
      an agency, partnership, joint venture or any other form of legal association
      between or among You, Apple or any Contributor, and You will not represent to
      the contrary, whether expressly, by implication, appearance or otherwise.

      13.3    Independent Development.   Nothing in this License will impair Apple's
      right to acquire, license, develop, have others develop for it, market and/or
      distribute technology or products that perform the same or similar functions as,
      or otherwise compete with, Modifications, Larger Works, technology or products
      that You may develop, produce, market or distribute.

      13.4    Waiver; Construction.  Failure by Apple or any Contributor to enforce any
      provision of this License will not be deemed a waiver of future enforcement of
      that or any other provision.  Any law or regulation which provides that the
      language of a contract shall be construed against the drafter will not apply to
      this License.

      13.5    Severability.  (a) If for any reason a court of competent jurisdiction
      finds any provision of this License, or portion thereof, to be unenforceable,
      that provision of the License will be enforced to the maximum extent permissible
      so as to effect the economic benefits and intent of the parties, and the
      remainder of this License will continue in full force and effect.  (b)
      Notwithstanding the foregoing, if applicable law prohibits or restricts You from
      fully and/or specifically complying with Sections 2 and/or 3 or prevents the
      enforceability of either of those Sections, this License will immediately
      terminate and You must immediately discontinue any use of the Covered Code and
      destroy all copies of it that are in your possession or control.

      13.6    Dispute Resolution.  Any litigation or other dispute resolution between
      You and Apple relating to this License shall take place in the Northern District
      of California, and You and Apple hereby consent to the personal jurisdiction of,
      and venue in, the state and federal courts within that District with respect to
      this License. The application of the United Nations Convention on Contracts for
      the International Sale of Goods is expressly excluded.

      13.7    Entire Agreement; Governing Law.  This License constitutes the entire
      agreement between the parties with respect to the subject matter hereof.  This
      License shall be governed by the laws of the United States and the State of
      California, except that body of California law concerning conflicts of law.

      Where You are located in the province of Quebec, Canada, the following clause
      applies:  The parties hereby confirm that they have requested that this License
      and all related documents be drafted in English.  Les parties ont exigé que le
      présent contrat et tous les documents connexes soient rédigés en anglais.
