+      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

+          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

+      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.

+      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.

+Apache Tuscany SCA Runtime
+==========================
+
+Automated installation from scratch on Ubuntu 9.10
+==================================================
+
+Tuscany provides an automated install script for Ubuntu 9.10. You can start
+with a fresh Ubuntu Server 9.10 system, the ubuntu-install script takes care
+of all the download, build and installation steps for you.
+
+The required system tools and libraries are downloaded and installed using
+apt-get. The Tuscany project and its dependencies (Apache HTTPD server, Apache
+Axis2/C etc) are downloaded, built and installed in the current directory.
+
+To run the automated installation:
+mkdir tuscany
+cd tuscany
+wget http://svn.apache.org/repos/asf/tuscany/sca-cpp/trunk/ubuntu/ubuntu-install
+chmod +x ./ubuntu-install
+./ubuntu-install
+
+The script will display each command as it's executed.
+
+That's all you need to do to build and install the Tuscany SCA runtime on
+Ubuntu 9.10.
+
+
+For manual build and install steps on other systems or if you need to customize
+your installation, read on...

+      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
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      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
+      institute patent litigation against any entity (including a
+      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
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          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.
+
+   END OF TERMS AND CONDITIONS

+Copyright OASIS 2005, 2009. All Rights Reserved.
+All capitalized terms in the following text have the meanings assigned to them in the OASIS Intellectual 
+Property Rights Policy (the "OASIS IPR Policy"). The full Policy may be found at the OASIS website.
+This document and translations of it may be copied and furnished to others, and derivative works that 
+comment on or otherwise explain it or assist in its implementation may be prepared, copied, published, 
+and distributed, in whole or in part, without restriction of any kind, provided that the above copyright 
+notice and this section are included on all such copies and derivative works. However, this document 
+itself may not be modified in any way, including by removing the copyright notice or references to OASIS, 
+except as needed for the purpose of developing any document or deliverable produced by an OASIS 
+Technical Committee (in which case the rules applicable to copyrights, as set forth in the OASIS IPR 
+Policy, must be followed) or as required to translate it into languages other than English.
+The limited permissions granted above are perpetual and will not be revoked by OASIS or its successors 
+or assigns.
+This document and the information contained herein is provided on an "AS IS" basis and OASIS 
+DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY 
+WARRANTY THAT THE USE OF THE INFORMATION HEREIN WILL NOT INFRINGE ANY OWNERSHIP 
+RIGHTS OR ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR 
+PURPOSE.
+OASIS requests that any OASIS Party or any other party that believes it has patent claims that would 
+necessarily be infringed by implementations of this OASIS Committee Specification or OASIS Standard, 
+to notify OASIS TC Administrator and provide an indication of its willingness to grant patent licenses to 
+such patent claims in a manner consistent with the IPR Mode of the OASIS Technical Committee that 
+produced this specification.
+OASIS invites any party to contact the OASIS TC Administrator if it is aware of a claim of ownership of 
+any patent claims that would necessarily be infringed by implementations of this specification by a patent 
+holder that is not willing to provide a license to such patent claims in a manner consistent with the IPR 
+Mode of the OASIS Technical Committee that produced this specification. OASIS may include such 
+claims on its website, but disclaims any obligation to do so.
+OASIS takes no position regarding the validity or scope of any intellectual property or other rights that 
+might be claimed to pertain to the implementation or use of the technology described in this document or 
+the extent to which any license under such rights might or might not be available; neither does it represent 
+that it has made any effort to identify any such rights. Information on OASIS' procedures with respect to 
+rights in any document or deliverable produced by an OASIS Technical Committee can be found on the 
+OASIS website. Copies of claims of rights made available for publication and any assurances of licenses 
+to be made available, or the result of an attempt made to obtain a general license or permission for the use 
+of such proprietary rights by implementers or users of this OASIS Committee Specification or OASIS 
+Standard, can be obtained from the OASIS TC Administrator. OASIS makes no representation that any 
+information or list of intellectual property rights will at any time be complete, or that any claims in such list 
+are, in fact, Essential Claims.
+The names "OASIS",  are trademarks of OASIS, the owner and developer of this specification, and should 
+be used only to refer to the organization and its official outputs. OASIS welcomes reference to, and 
+implementation and use of, specifications, while reserving the right to enforce its marks against misleading 
+uses. Please see http://www.oasis-open.org/who/trademark.php for above guidance.

+### This file configures various client-side behaviors.
+###
+### The commented-out examples below are intended to demonstrate
+### how to use this file.
+
+### Section for authentication and authorization customizations.
+[auth]
+### Set store-passwords to 'no' to avoid storing passwords in the
+### auth/ area of your config directory.  It defaults to 'yes'.
+### Note that this option only prevents saving of *new* passwords;
+### it doesn't invalidate existing passwords.  (To do that, remove
+### the cache files by hand as described in the Subversion book.)
+# store-passwords = no
+### Set store-auth-creds to 'no' to avoid storing any subversion
+### credentials in the auth/ area of your config directory.
+### It defaults to 'yes'.  Note that this option only prevents
+### saving of *new* credentials;  it doesn't invalidate existing
+### caches.  (To do that, remove the cache files by hand.)
+# store-auth-creds = no
+
+### Section for configuring external helper applications.
+[helpers]
+### Set editor to the command used to invoke your text editor.
+###   This will override the environment variables that Subversion
+###   examines by default to find this information ($EDITOR, 
+###   et al).
+# editor-cmd = editor (vi, emacs, notepad, etc.)
+### Set diff-cmd to the absolute path of your 'diff' program.
+###   This will override the compile-time default, which is to use
+###   Subversion's internal diff implementation.
+# diff-cmd = diff_program (diff, gdiff, etc.)
+### Set diff3-cmd to the absolute path of your 'diff3' program.
+###   This will override the compile-time default, which is to use
+###   Subversion's internal diff3 implementation.
+# diff3-cmd = diff3_program (diff3, gdiff3, etc.)
+### Set diff3-has-program-arg to 'true' or 'yes' if your 'diff3'
+###   program accepts the '--diff-program' option.
+# diff3-has-program-arg = [true | false]
+
+### Section for configuring tunnel agents.
+[tunnels]
+### Configure svn protocol tunnel schemes here.  By default, only
+### the 'ssh' scheme is defined.  You can define other schemes to
+### be used with 'svn+scheme://hostname/path' URLs.  A scheme
+### definition is simply a command, optionally prefixed by an
+### environment variable name which can override the command if it
+### is defined.  The command (or environment variable) may contain
+### arguments, using standard shell quoting for arguments with
+### spaces.  The command will be invoked as:
+###   <command> <hostname> svnserve -t
+### (If the URL includes a username, then the hostname will be
+### passed to the tunnel agent as <user>@<hostname>.)  If the
+### built-in ssh scheme were not predefined, it could be defined
+### as:
+# ssh = $SVN_SSH ssh
+### If you wanted to define a new 'rsh' scheme, to be used with
+### 'svn+rsh:' URLs, you could do so as follows:
+# rsh = rsh
+### Or, if you wanted to specify a full path and arguments:
+# rsh = /path/to/rsh -l myusername
+### On Windows, if you are specifying a full path to a command,
+### use a forward slash (/) or a paired backslash (\\) as the
+### path separator.  A single backslash will be treated as an
+### escape for the following character.
+
+### Section for configuring miscelleneous Subversion options.
+[miscellany]
+### Set global-ignores to a set of whitespace-delimited globs
+### which Subversion will ignore in its 'status' output.
+# global-ignores = *.o *.lo *.la #*# .*.rej *.rej .*~ *~ .#* .DS_Store
+### Set log-encoding to the default encoding for log messages
+# log-encoding = latin1
+### Set use-commit-times to make checkout/update/switch/revert
+### put last-committed timestamps on every file touched.
+# use-commit-times = yes
+### Set no-unlock to prevent 'svn commit' from automatically
+### releasing locks on files.
+# no-unlock = yes
+### Set enable-auto-props to 'yes' to enable automatic properties
+### for 'svn add' and 'svn import', it defaults to 'no'.
+### Automatic properties are defined in the section 'auto-props'.
+enable-auto-props = yes
+
+### Section for configuring automatic properties.
+[auto-props]
+### The format of the entries is:
+###   file-name-pattern = propname[=value][;propname[=value]...]
+### The file-name-pattern can contain wildcards (such as '*' and
+### '?').  All entries which match will be applied to the file.
+### Note that auto-props functionality must be enabled, which
+### is typically done by setting the 'enable-auto-props' option.

+ * This is the popular `times 33' hash algorithm which is used by
+ * perl and also appears in Berkeley DB. This is one of the best
+ * known hash functions for strings because it is both computed
+ * very fast and distributes very well.
+ *
+ * The originator may be Dan Bernstein but the code in Berkeley DB
+ * cites Chris Torek as the source. The best citation I have found
+ * is "Chris Torek, Hash function for text in C, Usenet message
+ * <27038@mimsy.umd.edu> in comp.lang.c , October, 1990." in Rich
+ * Salz's USENIX 1992 paper about INN which can be found at
+ * <http://citeseer.nj.nec.com/salz92internetnews.html>.
+ *
+ * The magic of number 33, i.e. why it works better than many other
+ * constants, prime or not, has never been adequately explained by
+ * anyone. So I try an explanation: if one experimentally tests all
+ * multipliers between 1 and 256 (as I did while writing a low-level
+ * data structure library some time ago) one detects that even
+ * numbers are not useable at all. The remaining 128 odd numbers
+ * (except for the number 1) work more or less all equally well.
+ * They all distribute in an acceptable way and this way fill a hash
+ * table with an average percent of approx. 86%.
+ *
+ * If one compares the chi^2 values of the variants (see
+ * Bob Jenkins ``Hashing Frequently Asked Questions'' at
+ * http://burtleburtle.net/bob/hash/hashfaq.html for a description
+ * of chi^2), the number 33 not even has the best value. But the
+ * number 33 and a few other equally good numbers like 17, 31, 63,
+ * 127 and 129 have nevertheless a great advantage to the remaining
+ * numbers in the large set of possible multipliers: their multiply
+ * operation can be replaced by a faster operation based on just one
+ * shift plus either a single addition or subtraction operation. And
+ * because a hash function has to both distribute good _and_ has to
+ * be very fast to compute, those few numbers should be preferred.

+
+    This schema document describes the XML namespace, in a form
+    suitable for import by other schema documents.
+
+    Note that local names in this namespace are intended to be defined
+    only by the World Wide Web Consortium or its subgroups.  The
+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of
+         the original XML Working Group.  This name is reserved by
+         the following decision of the W3C XML Plenary and
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication
+             the W3C XML Plenary on this 10th day of February, 2000

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang or xml:space attributes
+        on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2001/03/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>

+  <xs:documentation>In keeping with the XML Schema WG's standard versioning
+   policy, this schema document will persist at
+   http://www.w3.org/2001/03/xml.xsd.
+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself.  In other words, if the XML Schema namespace changes, the version
+   of this document at
+   http://www.w3.org/2001/xml.xsd will change
