/*
* Common Public License Version 0.5
*
* THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF
* THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE,
* REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES
* RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
*
* 1. DEFINITIONS
*
* "Contribution" means:
* a) in the case of the initial Contributor, the
* initial code and documentation distributed under
* this Agreement, and
*
* b) in the case of each subsequent Contributor:
* i) changes to the Program, and
* ii) additions to the Program;
*
* where such changes and/or additions to the Program
* originate from and are distributed by that
* particular Contributor. A Contribution 'originates'
* from a Contributor if it was added to the Program
* by such Contributor itself or anyone acting on such
* Contributor's behalf. Contributions do not include
* additions to the Program which: (i) are separate
* modules of software distributed in conjunction with
* the Program under their own license agreement, and
* (ii) are not derivative works of the Program.
*
*
* "Contributor" means any person or entity that distributes
* the Program.
*
* "Licensed Patents " mean patent claims licensable by a
* Contributor which are necessarily infringed by the use or
* sale of its Contribution alone or when combined with the
* Program.
*
* "Program" means the Contributions distributed in
* accordance with this Agreement.
*
* "Recipient" means anyone who receives the Program under
* this Agreement, including all Contributors.
*
* 2. GRANT OF RIGHTS
*
* a) Subject to the terms of this Agreement, each
* Contributor hereby grants Recipient a
* no - exclusive, worldwide, royalt - free copyright
* license to reproduce, prepare derivative works of,
* publicly display, publicly perform, distribute and
* sublicense the Contribution of such Contributor, if
* any, and such derivative works, in source code and
* object code form.
*
* b) Subject to the terms of this Agreement, each
* Contributor hereby grants Recipient a
* no - exclusive, worldwide, royalt - free patent
* license under Licensed Patents to make, use, sell,
* offer to sell, import and otherwise transfer the
* Contribution of such Contributor, if any, in source
* code and object code form. This patent license
* shall apply to the combination of the Contribution
* and the Program if, at the time the Contribution is
* added by the Contributor, such addition of the
* Contribution causes such combination to be covered
* by the Licensed Patents. The patent license shall
* not apply to any other combinations which include
* the Contribution. No hardware per se is licensed
* hereunder.
*
* c) Recipient understands that although each
* Contributor grants the licenses to its
* Contributions set forth herein, no assurances are
* provided by any Contributor that the Program does
* not infringe the patent or other intellectual
* property rights of any other entity. Each
* Contributor disclaims any liability to Recipient
* 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, each Recipient
* hereby assumes sole responsibility to secure any
* other intellectual property rights needed, if any.
*
* For example, if a third party patent license is
* required to allow Recipient to distribute the
* Program, it is Recipient's responsibility to
* acquire that license before distributing the
* Program.
*
* d) Each Contributor represents that to its
* knowledge it has sufficient copyright rights in its
* Contribution, if any, to grant the copyright
* license set forth in this Agreement.
*
* 3. REQUIREMENTS
*
* A Contributor may choose to distribute the Program in
* object code form under its own license agreement, provided
* that:
* a) it complies with the terms and conditions of
* this Agreement; and
*
* b) its license agreement:
* i) effectively disclaims on behalf of all
* Contributors all warranties and conditions, express
* and implied, including warranties or conditions of
* title and no - infringement, and implied warranties
* or conditions of merchantability and fitness for a
* particular purpose;
*
* ii) effectively excludes on behalf of all
* Contributors all liability for damages, including
* direct, indirect, special, incidental and
* consequential damages, such as lost profits;
*
* iii) states that any provisions which differ from
* this Agreement are offered by that Contributor
* alone and not by any other party; and
*
* iv) states that source code for the Program is
* available from such Contributor, and informs
* licensees how to obtain it in a reasonable manner
* on or through a medium customarily used for
* software exchange.
*
* When the Program is made available in source code form:
* a) it must be made available under this Agreement;
* and
* b) a copy of this Agreement must be included with
* each copy of the Program.
*
* Contributors may not remove or alter any copyright notices
* contained within the Program.
*
* Each Contributor must identify itself as the originator of
* its Contribution, if any, in a manner that reasonably
* allows subsequent Recipients to identify the originator of
* the Contribution.
*
*
* 4. COMMERCIAL DISTRIBUTION
*
* Commercial distributors of software may accept certain
* responsibilities with respect to end users, business
* partners and the like. While this license is intended to
* facilitate the commercial use of the Program, the
* Contributor who includes the Program in a commercial
* product offering should do so in a manner which does not
* create potential liability for other Contributors.
* Therefore, if a Contributor includes the Program in a
* commercial product offering, such Contributor ("Commercial
* Contributor") hereby agrees to defend and indemnify every
* other Contributor ("Indemnified Contributor") against any
* losses, damages and costs (collectively "Losses") arising
* from claims, lawsuits and other legal actions brought by a
* third party against the Indemnified Contributor to the
* extent caused by the acts or omissions of such Commercial
* Contributor in connection with its distribution of the
* Program in a commercial product offering. The obligations
* in this section do not apply to any claims or Losses
* relating to any actual or alleged intellectual property
* infringement. In order to qualify, an Indemnified
* Contributor must: a) promptly notify the Commercial
* Contributor in writing of such claim, and b) allow the
* Commercial Contributor to control, and cooperate with the
* Commercial Contributor in, the defense and any related
* settlement negotiations. The Indemnified Contributor may
* participate in any such claim at its own expense.
*
*
* For example, a Contributor might include the Program in a
* commercial product offering, Product X. That Contributor
* is then a Commercial Contributor. If that Commercial
* Contributor then makes performance claims, or offers
* warranties related to Product X, those performance claims
* and warranties are such Commercial Contributor's
* responsibility alone. Under this section, the Commercial
* Contributor would have to defend claims against the other
* Contributors related to those performance claims and
* warranties, and if a court requires any other Contributor
* to pay any damages as a result, the Commercial Contributor
* must pay those damages.
*
*
* 5. NO WARRANTY
*
* EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE
* PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT
* WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
* IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
* CONDITIONS OF TITLE, NO - INFRINGEMENT, MERCHANTABILITY OR
* FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
* responsible for determining the appropriateness of using
* and distributing the Program and assumes all risks
* associated with its exercise of rights under this
* Agreement, including but not limited to the risks and
* costs of program errors, compliance with applicable laws,
* damage to or loss of data, programs or equipment, and
* unavailability or interruption of operations.
*
* 6. DISCLAIMER OF LIABILITY
* EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER
* RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY
* FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY,
* OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION
* LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
* LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT
* (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT
* OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE
* OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
* POSSIBILITY OF SUCH DAMAGES.
*
* 7. GENERAL
*
* If any provision of this Agreement is invalid or
* unenforceable under applicable law, it shall not affect
* the validity or enforceability of the remainder of the
* terms of this Agreement, and without further action by the
* parties hereto, such provision shall be reformed to the
* minimum extent necessary to make such provision valid and
* enforceable.
*
*
* If Recipient institutes patent litigation against a
* Contributor with respect to a patent applicable to
* software (including a cros - claim or counterclaim in a
* lawsuit), then any patent licenses granted by that
* Contributor to such Recipient under this Agreement shall
* terminate as of the date such litigation is filed. In
* addition, If Recipient institutes patent litigation
* against any entity (including a cros - claim or
* counterclaim in a lawsuit) alleging that the Program
* itself (excluding combinations of the Program with other
* software or hardware) infringes such Recipient's
* patent(s), then such Recipient's rights granted under
* Section 2(b) shall terminate as of the date such
* litigation is filed.
*
* All Recipient's rights under this Agreement shall
* terminate if it fails to comply with any of the material
* terms or conditions of this Agreement and does not cure
* such failure in a reasonable period of time after becoming
* aware of such noncompliance. If all Recipient's rights
* under this Agreement terminate, Recipient agrees to cease
* use and distribution of the Program as soon as reasonably
* practicable. However, Recipient's obligations under this
* Agreement and any licenses granted by Recipient relating
* to the Program shall continue and survive.
*
* Everyone is permitted to copy and distribute copies of
* this Agreement, but in order to avoid inconsistency the
* Agreement is copyrighted and may only be modified in the
* following manner. The Agreement Steward reserves the right
* to publish new versions (including revisions) of this
* Agreement from time to time. No one other than the
* Agreement Steward has the right to modify this Agreement.
*
* IBM is the initial Agreement Steward. IBM may assign the
* responsibility to serve as the Agreement Steward to a
* suitable separate entity. Each new version of the
* Agreement will be given a distinguishing version number.
* The Program (including Contributions) may always be
* distributed subject to the version of the Agreement under
* which it was received. In addition, after a new version of
* the Agreement is published, Contributor may elect to
* distribute the Program (including its Contributions) under
* the new version. Except as expressly stated in Sections
* 2(a) and 2(b) above, Recipient receives no rights or
* licenses to the intellectual property of any Contributor
* under this Agreement, whether expressly, by implication,
* estoppel or otherwise. All rights in the Program not
* expressly granted under this Agreement are reserved.
*
*
* This Agreement is governed by the laws of the State of New
* York and the intellectual property laws of the United
* States of America. No party to this Agreement will bring a
* legal action under this Agreement more than one year after
* the cause of action arose. Each party waives its rights to
* a jury trial in any resulting litigation.
