2 *		Common Public License Version 0.5
3 *
4 *		THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF
5 *		THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE,
6 *		REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES
7 *		RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
8 *
9 *		1. DEFINITIONS
10 *
11 *		"Contribution" means:
12 *		      a) in the case of the initial Contributor, the
13 *		      initial code and documentation distributed under
14 *		      this Agreement, and
15 *
16 *		      b) in the case of each subsequent Contributor:
17 *		      i) changes to the Program, and
18 *		      ii) additions to the Program;
19 *
20 *		      where such changes and/or additions to the Program
21 *		      originate from and are distributed by that
22 *		      particular Contributor. A Contribution 'originates'
23 *		      from a Contributor if it was added to the Program
24 *		      by such Contributor itself or anyone acting on such
25 *		      Contributor's behalf. Contributions do not include
26 *		      additions to the Program which: (i) are separate
27 *		      modules of software distributed in conjunction with
28 *		      the Program under their own license agreement, and
29 *		      (ii) are not derivative works of the Program.
30 *
31 *
32 *		"Contributor" means any person or entity that distributes
33 *		the Program.
34 *
35 *		"Licensed Patents " mean patent claims licensable by a
36 *		Contributor which are necessarily infringed by the use or
37 *		sale of its Contribution alone or when combined with the
38 *		Program.
39 *
40 *		"Program" means the Contributions distributed in
41 *		accordance with this Agreement.
42 *
43 *		"Recipient" means anyone who receives the Program under
44 *		this Agreement, including all Contributors.
45 *
46 *		2. GRANT OF RIGHTS
47 *
48 *		      a) Subject to the terms of this Agreement, each
49 *		      Contributor hereby grants Recipient a
50 *		      no - exclusive, worldwide, royalt - free copyright
51 *		      license to reproduce, prepare derivative works of,
52 *		      publicly display, publicly perform, distribute and
53 *		      sublicense the Contribution of such Contributor, if
54 *		      any, and such derivative works, in source code and
55 *		      object code form.
56 *
57 *		      b) Subject to the terms of this Agreement, each
58 *		      Contributor hereby grants Recipient a
59 *		      no - exclusive, worldwide, royalt - free patent
60 *		      license under Licensed Patents to make, use, sell,
61 *		      offer to sell, import and otherwise transfer the
62 *		      Contribution of such Contributor, if any, in source
63 *		      code and object code form. This patent license
64 *		      shall apply to the combination of the Contribution
65 *		      and the Program if, at the time the Contribution is
66 *		      added by the Contributor, such addition of the
67 *		      Contribution causes such combination to be covered
68 *		      by the Licensed Patents. The patent license shall
69 *		      not apply to any other combinations which include
70 *		      the Contribution. No hardware per se is licensed
71 *		      hereunder.
72 *
73 *		      c) Recipient understands that although each
74 *		      Contributor grants the licenses to its
75 *		      Contributions set forth herein, no assurances are
76 *		      provided by any Contributor that the Program does
77 *		      not infringe the patent or other intellectual
78 *		      property rights of any other entity. Each
79 *		      Contributor disclaims any liability to Recipient
80 *		      for claims brought by any other entity based on
81 *		      infringement of intellectual property rights or
82 *		      otherwise. As a condition to exercising the rights
83 *		      and licenses granted hereunder, each Recipient
84 *		      hereby assumes sole responsibility to secure any
85 *		      other intellectual property rights needed, if any.
86 *
87 *		      For example, if a third party patent license is
88 *		      required to allow Recipient to distribute the
89 *		      Program, it is Recipient's responsibility to
90 *		      acquire that license before distributing the
91 *		      Program.
92 *
93 *		      d) Each Contributor represents that to its
94 *		      knowledge it has sufficient copyright rights in its
95 *		      Contribution, if any, to grant the copyright
96 *		      license set forth in this Agreement.
97 *
98 *		3. REQUIREMENTS
99 *
100 *		A Contributor may choose to distribute the Program in
101 *		object code form under its own license agreement, provided
102 *		that:
103 *		      a) it complies with the terms and conditions of
104 *		      this Agreement; and
105 *
106 *		      b) its license agreement:
107 *		      i) effectively disclaims on behalf of all
108 *		      Contributors all warranties and conditions, express
109 *		      and implied, including warranties or conditions of
110 *		      title and no - infringement, and implied warranties
111 *		      or conditions of merchantability and fitness for a
112 *		      particular purpose;
113 *
114 *		      ii) effectively excludes on behalf of all
115 *		      Contributors all liability for damages, including
116 *		      direct, indirect, special, incidental and
117 *		      consequential damages, such as lost profits;
118 *
119 *		      iii) states that any provisions which differ from
120 *		      this Agreement are offered by that Contributor
121 *		      alone and not by any other party; and
122 *
123 *		      iv) states that source code for the Program is
124 *		      available from such Contributor, and informs
125 *		      licensees how to obtain it in a reasonable manner
126 *		      on or through a medium customarily used for
127 *		      software exchange.
128 *
129 *		When the Program is made available in source code form:
130 *		      a) it must be made available under this Agreement;
131 *		      and
132 *		      b) a copy of this Agreement must be included with
133 *		      each copy of the Program.
134 *
135 *		Contributors may not remove or alter any copyright notices
136 *		contained within the Program.
137 *
138 *		Each Contributor must identify itself as the originator of
139 *		its Contribution, if any, in a manner that reasonably
140 *		allows subsequent Recipients to identify the originator of
141 *		the Contribution.
142 *
143 *
144 *		4. COMMERCIAL DISTRIBUTION
145 *
146 *		Commercial distributors of software may accept certain
147 *		responsibilities with respect to end users, business
148 *		partners and the like. While this license is intended to
149 *		facilitate the commercial use of the Program, the
150 *		Contributor who includes the Program in a commercial
151 *		product offering should do so in a manner which does not
152 *		create potential liability for other Contributors.
153 *		Therefore, if a Contributor includes the Program in a
154 *		commercial product offering, such Contributor ("Commercial
155 *		Contributor") hereby agrees to defend and indemnify every
156 *		other Contributor ("Indemnified Contributor") against any
157 *		losses, damages and costs (collectively "Losses") arising
158 *		from claims, lawsuits and other legal actions brought by a
159 *		third party against the Indemnified Contributor to the
160 *		extent caused by the acts or omissions of such Commercial
161 *		Contributor in connection with its distribution of the
162 *		Program in a commercial product offering. The obligations
163 *		in this section do not apply to any claims or Losses
164 *		relating to any actual or alleged intellectual property
165 *		infringement. In order to qualify, an Indemnified
166 *		Contributor must: a) promptly notify the Commercial
167 *		Contributor in writing of such claim, and b) allow the
168 *		Commercial Contributor to control, and cooperate with the
169 *		Commercial Contributor in, the defense and any related
170 *		settlement negotiations. The Indemnified Contributor may
171 *		participate in any such claim at its own expense.
172 *
173 *
174 *		For example, a Contributor might include the Program in a
175 *		commercial product offering, Product X. That Contributor
176 *		is then a Commercial Contributor. If that Commercial
177 *		Contributor then makes performance claims, or offers
178 *		warranties related to Product X, those performance claims
179 *		and warranties are such Commercial Contributor's
180 *		responsibility alone. Under this section, the Commercial
181 *		Contributor would have to defend claims against the other
182 *		Contributors related to those performance claims and
183 *		warranties, and if a court requires any other Contributor
184 *		to pay any damages as a result, the Commercial Contributor
185 *		must pay those damages.
186 *
187 *
188 *		5. NO WARRANTY
189 *
190 *		EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE
191 *		PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT
192 *		WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
193 *		IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
194 *		CONDITIONS OF TITLE, NO - INFRINGEMENT, MERCHANTABILITY OR
195 *		FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
196 *		responsible for determining the appropriateness of using
197 *		and distributing the Program and assumes all risks
198 *		associated with its exercise of rights under this
199 *		Agreement, including but not limited to the risks and
200 *		costs of program errors, compliance with applicable laws,
201 *		damage to or loss of data, programs or equipment, and
202 *		unavailability or interruption of operations.
203 *
204 *		6. DISCLAIMER OF LIABILITY
205 *		EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER
206 *		RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY
207 *		FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY,
208 *		OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION
209 *		LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
210 *		LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT
211 *		(INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT
212 *		OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE
213 *		OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
214 *		POSSIBILITY OF SUCH DAMAGES.
215 *
216 *		7. GENERAL
217 *
218 *		If any provision of this Agreement is invalid or
219 *		unenforceable under applicable law, it shall not affect
220 *		the validity or enforceability of the remainder of the
221 *		terms of this Agreement, and without further action by the
222 *		parties hereto, such provision shall be reformed to the
223 *		minimum extent necessary to make such provision valid and
224 *		enforceable.
225 *
226 *
227 *		If Recipient institutes patent litigation against a
228 *		Contributor with respect to a patent applicable to
229 *		software (including a cros - claim or counterclaim in a
230 *		lawsuit), then any patent licenses granted by that
231 *		Contributor to such Recipient under this Agreement shall
232 *		terminate as of the date such litigation is filed. In
233 *		addition, If Recipient institutes patent litigation
234 *		against any entity (including a cros - claim or
235 *		counterclaim in a lawsuit) alleging that the Program
236 *		itself (excluding combinations of the Program with other
237 *		software or hardware) infringes such Recipient's
238 *		patent(s), then such Recipient's rights granted under
239 *		Section 2(b) shall terminate as of the date such
240 *		litigation is filed.
241 *
242 *		All Recipient's rights under this Agreement shall
243 *		terminate if it fails to comply with any of the material
244 *		terms or conditions of this Agreement and does not cure
245 *		such failure in a reasonable period of time after becoming
246 *		aware of such noncompliance. If all Recipient's rights
247 *		under this Agreement terminate, Recipient agrees to cease
248 *		use and distribution of the Program as soon as reasonably
249 *		practicable. However, Recipient's obligations under this
250 *		Agreement and any licenses granted by Recipient relating
251 *		to the Program shall continue and survive.
252 *
253 *		Everyone is permitted to copy and distribute copies of
254 *		this Agreement, but in order to avoid inconsistency the
255 *		Agreement is copyrighted and may only be modified in the
256 *		following manner. The Agreement Steward reserves the right
257 *		to publish new versions (including revisions) of this
258 *		Agreement from time to time. No one other than the
259 *		Agreement Steward has the right to modify this Agreement.
260 *
261 *		IBM is the initial Agreement Steward. IBM may assign the
262 *		responsibility to serve as the Agreement Steward to a
263 *		suitable separate entity. Each new version of the
264 *		Agreement will be given a distinguishing version number.
265 *		The Program (including Contributions) may always be
266 *		distributed subject to the version of the Agreement under
267 *		which it was received. In addition, after a new version of
268 *		the Agreement is published, Contributor may elect to
269 *		distribute the Program (including its Contributions) under
270 *		the new version. Except as expressly stated in Sections
271 *		2(a) and 2(b) above, Recipient receives no rights or
272 *		licenses to the intellectual property of any Contributor
273 *		under this Agreement, whether expressly, by implication,
274 *		estoppel or otherwise. All rights in the Program not
275 *		expressly granted under this Agreement are reserved.
276 *
277 *
278 *		This Agreement is governed by the laws of the State of New
279 *		York and the intellectual property laws of the United
280 *		States of America. No party to this Agreement will bring a
281 *		legal action under this Agreement more than one year after
282 *		the cause of action arose. Each party waives its rights to
283 *		a jury trial in any resulting litigation.
