+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) 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, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+The Apache Tuscany distribution includes a number of subcomponents with
+separate copyright notices and license terms. Your use of the source
+code for the these subcomponents is subject to the terms and
+conditions of the following licenses. 
+
+===============================================================================
+
+For the Eclipse Modeling Framework component and the Celtix binding:
+
+Eclipse Public License - v 1.0
+
+THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+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 non-exclusive, worldwide, royalty-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 non-exclusive, worldwide, royalty-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 non-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, NON-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 any entity
+(including a cross-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. The Eclipse Foundation
+is the initial Agreement Steward. The Eclipse Foundation 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.

+
+
+3. Distribution Obligations.
+
+      3.1. Application of License.
+      The Modifications which You create or to which You contribute are
+governed by the terms of this License, including without limitation Section
+2.2. The Source Code version of Covered Code may be distributed only under the
+terms of this License or a future version of this License released under
+Section 6.1, and You must include a copy of this License with every copy of
+the Source Code You distribute. You may not offer or impose any terms on any
+Source Code version that alters or restricts the applicable version of this
+License or the recipients' rights hereunder. However, You may include an
+additional document offering the additional rights described in Section 3.5.
+
+      3.2. Availability of Source Code.
+      Any Modification which You create or to which You contribute must be
+made available in Source Code form under the terms of this License either on
+the same media as an Executable version or via an accepted Electronic
+Distribution Mechanism to anyone to whom you made an Executable version
+available; and if made available via Electronic Distribution Mechanism, must
+remain available for at least twelve (12) months after the date it initially
+became available, or at least six (6) months after a subsequent version of
+that particular Modification has been made available to such recipients. You
+are responsible for ensuring that the Source Code version remains available
+even if the Electronic Distribution Mechanism is maintained by a third party.
+
+      3.3. Description of Modifications.
+      You must cause all Covered Code to which You contribute to contain a
+file documenting the changes You made to create that Covered Code and the date
+of any change. You must include a prominent statement that the Modification is
+derived, directly or indirectly, from Original Code provided by the Initial
+Developer and including the name of the Initial Developer in (a) the Source
+Code, and (b) in any notice in an Executable version or related documentation
+in which You describe the origin or ownership of the Covered Code.
+
+      3.4. Intellectual Property Matters
+            (a) Third Party Claims.
+            If Contributor has knowledge that a license under a third party's
+intellectual property rights is required to exercise the rights granted by
+such Contributor under Sections 2.1 or 2.2, Contributor must include a text
+file with the Source Code distribution titled "LEGAL" which describes the
+claim and the party making the claim in sufficient detail that a recipient
+will know whom to contact. If Contributor obtains such knowledge after the
+Modification is made available as described in Section 3.2, Contributor shall
+promptly modify the LEGAL file in all copies Contributor makes available
+thereafter and shall take other steps (such as notifying appropriate mailing
+lists or newsgroups) reasonably calculated to inform those who received the
+Covered Code that new knowledge has been obtained.
+
+            (b) Contributor APIs.
+            If Contributor's Modifications include an application programming
+interface and Contributor has knowledge of patent licenses which are
+reasonably necessary to implement that API, Contributor must also include this
+information in the LEGAL file.
+             
+                (c)    Representations.
+            Contributor represents that, except as disclosed pursuant to
+Section 3.4(a) above, Contributor believes that Contributor's Modifications
+are Contributor's original creation(s) and/or Contributor has sufficient
+rights to grant the rights conveyed by this License.
+
+
+      3.5. Required Notices.
+      You must duplicate the notice in Exhibit A in each file of the Source
+Code.  If it is not possible to put such notice in a particular Source Code
+file due to its structure, then You must include such notice in a location
+(such as a relevant directory) where a user would be likely to look for such a
+notice.  If You created one or more Modification(s) You may add your name as a
+Contributor to the notice described in Exhibit A.  You must also duplicate
+this License in any documentation for the Source Code where You describe
+recipients' rights or ownership rights relating to Covered Code.  You may
+choose to offer, and to charge a fee for, warranty, support, indemnity or
+liability obligations to one or more recipients of Covered Code. However, You
+may do so only on Your own behalf, and not on behalf of the Initial Developer
+or any Contributor. You must make it absolutely clear than any such warranty,
+support, indemnity or liability obligation is offered by You alone, and You
+hereby agree to indemnify the Initial Developer and every Contributor for any
+liability incurred by the Initial Developer or such Contributor as a result of
+warranty, support, indemnity or liability terms You offer.
+
+      3.6. Distribution of Executable Versions.
+      You may distribute Covered Code in Executable form only if the
+requirements of Section 3.1-3.5 have been met for that Covered Code, and if
+You include a notice stating that the Source Code version of the Covered Code
+is available under the terms of this License, including a description of how
+and where You have fulfilled the obligations of Section 3.2. The notice must
+be conspicuously included in any notice in an Executable version, related
+documentation or collateral in which You describe recipients' rights relating
+to the Covered Code. You may distribute the Executable version of Covered Code
+or ownership rights under a license of Your choice, which may contain terms
+different from this License, provided that You are in compliance with the
+terms of this License and that the license for the Executable version does not
+attempt to limit or alter the recipient's rights in the Source Code version
+from the rights set forth in this License. If You distribute the Executable
+version under a different license You must make it absolutely clear that any
+terms which differ from this License are offered by You alone, not by the
+Initial Developer or any Contributor. You hereby agree to indemnify the
+Initial Developer and every Contributor for any liability incurred by the
+Initial Developer or such Contributor as a result of any such terms You offer.
+
+      3.7. 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 such a case, You must make sure the requirements of this
+License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+      If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Code due to statute,
+judicial order, or regulation then You must: (a) comply with the terms of this
+License to the maximum extent possible; and (b) describe the limitations and
+the code they affect. Such description must be included in the LEGAL file
+described in Section 3.4 and must be included with all distributions of the
+Source Code. Except to the extent prohibited by statute or regulation, such
+description must be sufficiently detailed for a recipient of ordinary skill to
+be able to understand it.
+
+5. Application of this License.
+
+      This License applies to code to which the Initial Developer has attached
+the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+      6.1. New Versions.
+      Netscape Communications Corporation ("Netscape") may publish revised
+and/or new versions of the License from time to time. Each version will be
+given a distinguishing version number.
+
+      6.2. Effect of New Versions.
+      Once Covered Code has been published under a particular version of the
+License, You may always continue to use it under the terms of that version.
+You may also choose to use such Covered Code under the terms of any subsequent
+version of the License published by Netscape. No one other than Netscape has
+the right to modify the terms applicable to Covered Code created under this
+License.
+
+      6.3. Derivative Works.
+      If You create or use a modified version of this License (which you may
+only do in order to apply it to code which is not already Covered Code
+governed by this License), You must (a) rename Your license so that the
+phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape", "MPL", "NPL" or
+any confusingly similar phrase do not appear in your license (except to note
+that your license differs from this License) and (b) otherwise make it clear
+that Your version of the license contains terms which differ from the Mozilla
+Public License and Netscape Public License. (Filling in the name of the
+Initial Developer, Original Code or Contributor in the notice described in
+Exhibit A shall not of themselves be deemed to be modifications of this
+License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+      COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT
+LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE,
+FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE
+QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED
+CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY
+OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR
+CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS
+LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS
+DISCLAIMER.
+
+8. TERMINATION.
+
+      8.1.  This License and the rights granted hereunder will terminate
+automatically if You fail to comply with terms herein and fail to cure such
+breach within 30 days of becoming aware of the breach. All sublicenses to the
+Covered Code which are properly granted shall survive any termination of this
+License. Provisions which, by their nature, must remain in effect beyond the
+termination of this License shall survive.
+
+      8.2.  If You initiate litigation by asserting a patent infringement
+claim (excluding declatory judgment actions) against Initial Developer or a
+Contributor (the Initial Developer or Contributor against whom You file such
+action is referred to as "Participant")  alleging that:
+
+      (a)  such Participant's Contributor Version directly or indirectly
+infringes any patent, then any and all rights granted by such Participant to
+You under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice
+from Participant terminate prospectively, unless if within 60 days after
+receipt of notice You either: (i)  agree in writing to pay Participant a
+mutually agreeable reasonable royalty for Your past and future use of
+Modifications made by such Participant, or (ii) withdraw Your litigation claim
+with respect to the Contributor Version against such Participant.  If within
+60 days of notice, a reasonable royalty and payment arrangement are not
+mutually agreed upon in writing by the parties or the litigation claim is not
+withdrawn, the rights granted by Participant to You under Sections 2.1 and/or
+2.2 automatically terminate at the expiration of the 60 day notice period
+specified above.
+
+      (b)  any software, hardware, or device, other than such Participant's
+Contributor Version, directly or indirectly infringes any patent, then any
+rights granted to You by such Participant under Sections 2.1(b) and 2.2(b) are
+revoked effective as of the date You first made, used, sold, distributed, or
+had made, Modifications made by that Participant.
+
+      8.3.  If You assert a patent infringement claim against Participant
+alleging that such Participant's Contributor Version directly or indirectly
+infringes any patent where such claim is resolved (such as by license or
+settlement) prior to the initiation of patent infringement litigation, then
+the reasonable value of the licenses granted by such Participant under
+Sections 2.1 or 2.2 shall be taken into account in determining the amount or
+value of any payment or license.
+
+      8.4.  In the event of termination under Sections 8.1 or 8.2 above,  all
+end user license agreements (excluding distributors and resellers) which have
+been validly granted by You or any distributor hereunder prior to termination
+shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+      UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+(INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY
+SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT,
+SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING,
+WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
+FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES,
+EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH
+DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH
+OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT
+APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS
+EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+      The Covered Code is a "commercial item," as that term is defined in 48
+C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and
+"commercial computer software documentation," as such terms are used in 48
+C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R.
+227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users
+acquire Covered Code with only those rights set forth herein.
+
+11. MISCELLANEOUS.
+
+      This License represents the complete agreement concerning subject matter
+hereof. If any provision of this License is held to be unenforceable, such
+provision shall be reformed only to the extent necessary to make it
+enforceable. This License shall be governed by California law provisions
+(except to the extent applicable law, if any, provides otherwise), excluding
+its conflict-of-law provisions. With respect to disputes in which at least one
+party is a citizen of, or an entity chartered or registered to do business in
+the United States of America, any litigation relating to this License shall be
+subject to the jurisdiction of the Federal Courts of the Northern District of
+California, with venue lying in Santa Clara County, California, with the
+losing party responsible for costs, including without limitation, court costs
+and reasonable attorneys' fees and expenses. The application of the United
+Nations Convention on Contracts for the International Sale of Goods is
+expressly excluded. Any law or regulation which provides that the language of
+a contract shall be construed against the drafter shall not apply to this
+License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+      As between Initial Developer and the Contributors, each party is
+responsible for claims and damages arising, directly or indirectly, out of its
+utilization of rights under this License and You agree to work with Initial
+Developer and Contributors to distribute such responsibility on an equitable
+basis. Nothing herein is intended or shall be deemed to constitute any
+admission of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+      Initial Developer may designate portions of the Covered Code as
+Multiple-Licensed.  Multiple-Licensed means that the Initial Developer permits
+you to utilize portions of the Covered Code under Your choice of the MPL or
+the alternative licenses, if any, specified by the Initial Developer in the

+
+                  (c) The licenses granted in Sections 2.1(a) and (b)

+
+      3. Distribution Obligations.
+
+            3.1. Availability of Source Code.
+
+            Any Covered Software that You distribute or otherwise make
+            available in Executable form must also be made available in
+            Source Code form and that Source Code form must be
+            distributed only under the terms of this License. You must
+            include a copy of this License with every copy of the
+            Source Code form of the Covered Software You distribute or
+            otherwise make available. You must inform recipients of any
+            such Covered Software in Executable form as to how they can
+            obtain such Covered Software in Source Code form in a
+            reasonable manner on or through a medium customarily used
+            for software exchange.
+
+            3.2. Modifications.
+
+            The Modifications that You create or to which You
+            contribute are governed by the terms of this License. You
+            represent that You believe Your Modifications are Your
+            original creation(s) and/or You have sufficient rights to
+            grant the rights conveyed by this License.
+
+            3.3. Required Notices.
+
+            You must include a notice in each of Your Modifications
+            that identifies You as the Contributor of the Modification.
+            You may not remove or alter any copyright, patent or
+            trademark notices contained within the Covered Software, or
+            any notices of licensing or any descriptive text giving
+            attribution to any Contributor or the Initial Developer.
+
+            3.4. Application of Additional Terms.
+
+            You may not offer or impose any terms on any Covered
+            Software in Source Code form that alters or restricts the
+            applicable version of this License or the recipients'
+            rights hereunder. You may choose to offer, and to charge a
+            fee for, warranty, support, indemnity or liability
+            obligations to one or more recipients of Covered Software.
+            However, you may do so only on Your own behalf, and not on
+            behalf of the Initial Developer or any Contributor. You
+            must make it absolutely clear that any such warranty,
+            support, indemnity or liability obligation is offered by
+            You alone, and You hereby agree to indemnify the Initial
+            Developer and every Contributor for any liability incurred
+            by the Initial Developer or such Contributor as a result of
+            warranty, support, indemnity or liability terms You offer.
+          
+
+            3.5. Distribution of Executable Versions.
+
+            You may distribute the Executable form of the Covered
+            Software under the terms of this License or under the terms
+            of a license of Your choice, which may contain terms
+            different from this License, provided that You are in
+            compliance with the terms of this License and that the
+            license for the Executable form does not attempt to limit
+            or alter the recipient's rights in the Source Code form
+            from the rights set forth in this License. If You
+            distribute the Covered Software in Executable form under a
+            different license, You must make it absolutely clear that
+            any terms which differ from this License are offered by You
+            alone, not by the Initial Developer or Contributor. You
+            hereby agree to indemnify the Initial Developer and every
+            Contributor for any liability incurred by the Initial
+            Developer or such Contributor as a result of any such terms
+            You offer.
+
+            3.6. Larger Works.
+
+            You may create a Larger Work by combining Covered Software
+            with other code not governed by the terms of this License
+            and distribute the Larger Work as a single product. In such
+            a case, You must make sure the requirements of this License
+            are fulfilled for the Covered Software. 
+            
+      4. Versions of the License. 
+
+            4.1. New Versions.
+
+            Sun Microsystems, Inc. is the initial license steward and
+            may publish revised and/or new versions of this License
+            from time to time. Each version will be given a
+            distinguishing version number. Except as provided in
+            Section 4.3, no one other than the license steward has the
+            right to modify this License. 
+
+            4.2. Effect of New Versions.
+
+            You may always continue to use, distribute or otherwise
+            make the Covered Software available under the terms of the
+            version of the License under which You originally received
+            the Covered Software. If the Initial Developer includes a
+            notice in the Original Software prohibiting it from being
+            distributed or otherwise made available under any
+            subsequent version of the License, You must distribute and
+            make the Covered Software available under the terms of the
+            version of the License under which You originally received
+            the Covered Software. Otherwise, You may also choose to
+            use, distribute or otherwise make the Covered Software
+            available under the terms of any subsequent version of the
+            License published by the license steward. 
+
+            4.3. Modified Versions.
+
+            When You are an Initial Developer and You want to create a
+            new license for Your Original Software, You may create and
+            use a modified version of this License if You: (a) rename
+            the license and remove any references to the name of the
+            license steward (except to note that the license differs
+            from this License); and (b) otherwise make it clear that
+            the license contains terms which differ from this License.
+            
+
+      5. DISCLAIMER OF WARRANTY.
+
+      COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS"
+      BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+      INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED
+      SOFTWARE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR
+      PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND
+      PERFORMANCE OF THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY
+      COVERED SOFTWARE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE
+      INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF
+      ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF
+      WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+      ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS
+      DISCLAIMER. 
+
+      6. TERMINATION. 
+
+            6.1. This License and the rights granted hereunder will
+            terminate automatically if You fail to comply with terms
+            herein and fail to cure such breach within 30 days of
+            becoming aware of the breach. Provisions which, by their
+            nature, must remain in effect beyond the termination of
+            this License shall survive.
+
+            6.2. If You assert a patent infringement claim (excluding
+            declaratory judgment actions) against Initial Developer or
+            a Contributor (the Initial Developer or Contributor against
+            whom You assert such claim is referred to as "Participant")
+            alleging that the Participant Software (meaning the
+            Contributor Version where the Participant is a Contributor
+            or the Original Software where the Participant is the
+            Initial Developer) directly or indirectly infringes any
+            patent, then any and all rights granted directly or
+            indirectly to You by such Participant, the Initial
+            Developer (if the Initial Developer is not the Participant)
+            and all Contributors under Sections 2.1 and/or 2.2 of this
+            License shall, upon 60 days notice from Participant
+            terminate prospectively and automatically at the expiration
+            of such 60 day notice period, unless if within such 60 day
+            period You withdraw Your claim with respect to the
+            Participant Software against such Participant either
+            unilaterally or pursuant to a written agreement with
+            Participant.
+
+            6.3. In the event of termination under Sections 6.1 or 6.2
+            above, all end user licenses that have been validly granted
+            by You or any distributor hereunder prior to termination
+            (excluding licenses granted to You by any distributor)
+            shall survive termination.
+
+      7. LIMITATION OF LIABILITY.
+
+      UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+      (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
+      INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
+      COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE
+      LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
+      CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
+      LIMITATION, DAMAGES FOR LOST PROFITS, LOSS OF GOODWILL, WORK
+      STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+      COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+      INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+      LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL
+      INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT
+      APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO
+      NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR
+      CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT
+      APPLY TO YOU.
+
+      8. U.S. GOVERNMENT END USERS.
+
+      The Covered Software is a "commercial item," as that term is
+      defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial
+      computer software" (as that term is defined at 48 C.F.R. 
+      252.227-7014(a)(1)) and "commercial computer software
+      documentation" as such terms are used in 48 C.F.R. 12.212 (Sept.
+      1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1
+      through 227.7202-4 (June 1995), all U.S. Government End Users
+      acquire Covered Software with only those rights set forth herein.
+      This U.S. Government Rights clause is in lieu of, and supersedes,
+      any other FAR, DFAR, or other clause or provision that addresses
+      Government rights in computer software under this License.
+
+      9. MISCELLANEOUS.
+
+      This License represents the complete agreement concerning subject
+      matter hereof. If any provision of this License is held to be
+      unenforceable, such provision shall be reformed only to the
+      extent necessary to make it enforceable. This License shall be
+      governed by the law of the jurisdiction specified in a notice
+      contained within the Original Software (except to the extent
+      applicable law, if any, provides otherwise), excluding such
+      jurisdiction's conflict-of-law provisions. Any litigation
+      relating to this License shall be subject to the jurisdiction of
+      the courts located in the jurisdiction and venue specified in a
+      notice contained within the Original Software, with the losing
+      party responsible for costs, including, without limitation, court
+      costs and reasonable attorneys' fees and expenses. The
+      application of the United Nations Convention on Contracts for the
+      International Sale of Goods is expressly excluded. Any law or
+      regulation which provides that the language of a contract shall
+      be construed against the drafter shall not apply to this License.
+      You agree that You alone are responsible for compliance with the
+      United States export administration regulations (and the export
+      control laws and regulation of any other countries) when You use,
+      distribute or otherwise make available any Covered Software.
+
+      10. RESPONSIBILITY FOR CLAIMS.
+
+      As between Initial Developer and the Contributors, each party is
+      responsible for claims and damages arising, directly or
+      indirectly, out of its utilization of rights under this License
+      and You agree to work with Initial Developer and Contributors to
+      distribute such responsibility on an equitable basis. Nothing
+      herein is intended or shall be deemed to constitute any admission
+      of liability.

+Apache Tuscany M1 build (May, 2006)
+===================================
+
+http://incubator.apache.org/tuscany/
+
+Tuscany is an effort undergoing incubation at the Apache Software Foundation
+(ASF), sponsored by the Web Services PMC.
+
+Incubation is required of all newly accepted projects until a further review
+indicates that the infrastructure, communications, and decision making process
+have stabilized in a manner consistent with other successful ASF projects. 
+
+While incubation status is not necessarily a reflection of the completeness or 
+stability of the code, it does indicate that the project has yet to be fully
+endorsed by the ASF.
+
+
+Support
+-------
+
+Any problem with this release can be reported to the Tuscany mailing list 
+or in the JIRA issue tracker.
+
+Mailing list subscription:
+    tuscany-dev-subscribe@ws.apache.org
+
+Jira:
+    http://issues.apache.org/jira/browse/Tuscany
+
+
+Thank you for using Tuscany!
