68 |                <setup> task.
69 |              - customize it to your needs.
70 |          - Customize the whole script.
71 |              - copy/paste the content of the rules files (minus the top node)
72 |                into this file, *after* the <setup> task
73 |              - disable the import of the rules by changing the setup task
74 |                below to <setup import="false" />.
75 |              - customize to your needs.

 18 |    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
 19 | 
 20 |    1. Definitions.
 21 |

 24 | 
 25 |       "Licensor" shall mean the copyright owner or entity authorized by
 26 |       the copyright owner that is granting the License.
 27 | 
 28 |       "Legal Entity" shall mean the union of the acting entity and all
 29 |       other entities that control, are controlled by, or are under common
 30 |       control with that entity. For the purposes of this definition,
 31 |       "control" means (i) the power, direct or indirect, to cause the
 32 |       direction or management of such entity, whether by contract or
 33 |       otherwise, or (ii) ownership of fifty percent (50%) or more of the
 34 |       outstanding shares, or (iii) beneficial ownership of such entity.
 35 | 
 36 |       "You" (or "Your") shall mean an individual or Legal Entity
 37 |       exercising permissions granted by this License.
 38 | 
 39 |       "Source" form shall mean the preferred form for making modifications,

 42 | 
 43 |       "Object" form shall mean any form resulting from mechanical
 44 |       transformation or translation of a Source form, including but
 45 |       not limited to compiled object code, generated documentation,
 46 |       and conversions to other media types.
 47 | 
 48 |       "Work" shall mean the work of authorship, whether in Source or
 49 |       Object form, made available under the License, as indicated by a
 50 |       copyright notice that is included in or attached to the work
 51 |       (an example is provided in the Appendix below).
 52 | 
 53 |       "Derivative Works" shall mean any work, whether in Source or Object
 54 |       form, that is based on (or derived from) the Work and for which the
 55 |       editorial revisions, annotations, elaborations, or other modifications
 56 |       represent, as a whole, an original work of authorship. For the purposes
 57 |       of this License, Derivative Works shall not include works that remain
 58 |       separable from, or merely link (or bind by name) to the interfaces of,
 59 |       the Work and Derivative Works thereof.
 60 | 
 61 |       "Contribution" shall mean any work of authorship, including
 62 |       the original version of the Work and any modifications or additions
 63 |       to that Work or Derivative Works thereof, that is intentionally
 64 |       submitted to Licensor for inclusion in the Work by the copyright owner
 65 |       or by an individual or Legal Entity authorized to submit on behalf of
 66 |       the copyright owner. For the purposes of this definition, "submitted"
 67 |       means any form of electronic, verbal, or written communication sent

 72 |       excluding communication that is conspicuously marked or otherwise
 73 |       designated in writing by the copyright owner as "Not a Contribution."
 74 | 
 75 |       "Contributor" shall mean Licensor and any individual or Legal Entity
 76 |       on behalf of whom a Contribution has been received by Licensor and
 77 |       subsequently incorporated within the Work.
 78 | 
 79 |    2. Grant of Copyright License. Subject to the terms and conditions of
 80 |       this License, each Contributor hereby grants to You a perpetual,
 81 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 82 |       copyright license to reproduce, prepare Derivative Works of,
 83 |       publicly display, publicly perform, sublicense, and distribute the
 84 |       Work and such Derivative Works in Source or Object form.
 85 | 
 86 |    3. Grant of Patent License. Subject to the terms and conditions of
 87 |       this License, each Contributor hereby grants to You a perpetual,
 88 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 89 |       (except as stated in this section) patent license to make, have made,
 90 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 91 |       where such license applies only to those patent claims licensable
 92 |       by such Contributor that are necessarily infringed by their
 93 |       Contribution(s) alone or by combination of their Contribution(s)
 94 |       with the Work to which such Contribution(s) was submitted. If You
 95 |       institute patent litigation against any entity (including a
 96 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 97 |       or a Contribution incorporated within the Work constitutes direct
 98 |       or contributory patent infringement, then any patent licenses
 99 |       granted to You under this License for that Work shall terminate
100 |       as of the date such litigation is filed.
101 | 
102 |    4. Redistribution. You may reproduce and distribute copies of the
103 |       Work or Derivative Works thereof in any medium, with or without
104 |       modifications, and in Source or Object form, provided that You
105 |       meet the following conditions:
106 | 
107 |       (a) You must give any other recipients of the Work or
108 |           Derivative Works a copy of this License; and
109 | 
110 |       (b) You must cause any modified files to carry prominent notices
111 |           stating that You changed the files; and
112 | 
113 |       (c) You must retain, in the Source form of any Derivative Works
114 |           that You distribute, all copyright, patent, trademark, and
115 |           attribution notices from the Source form of the Work,
116 |           excluding those notices that do not pertain to any part of
117 |           the Derivative Works; and
118 | 
119 |       (d) If the Work includes a "NOTICE" text file as part of its
120 |           distribution, then any Derivative Works that You distribute must
121 |           include a readable copy of the attribution notices contained
122 |           within such NOTICE file, excluding those notices that do not
123 |           pertain to any part of the Derivative Works, in at least one
124 |           of the following places: within a NOTICE text file distributed
125 |           as part of the Derivative Works; within the Source form or
126 |           documentation, if provided along with the Derivative Works; or,
127 |           within a display generated by the Derivative Works, if and
128 |           wherever such third-party notices normally appear. The contents
129 |           of the NOTICE file are for informational purposes only and
130 |           do not modify the License. You may add Your own attribution
131 |           notices within Derivative Works that You distribute, alongside
132 |           or as an addendum to the NOTICE text from the Work, provided
133 |           that such additional attribution notices cannot be construed
134 |           as modifying the License.
135 | 
136 |       You may add Your own copyright statement to Your modifications and
137 |       may provide additional or different license terms and conditions
138 |       for use, reproduction, or distribution of Your modifications, or
139 |       for any such Derivative Works as a whole, provided Your use,
140 |       reproduction, and distribution of the Work otherwise complies with
141 |       the conditions stated in this License.
142 | 
143 |    5. Submission of Contributions. Unless You explicitly state otherwise,
144 |       any Contribution intentionally submitted for inclusion in the Work
145 |       by You to the Licensor shall be under the terms and conditions of
146 |       this License, without any additional terms or conditions.
147 |       Notwithstanding the above, nothing herein shall supersede or modify
148 |       the terms of any separate license agreement you may have executed
149 |       with Licensor regarding such Contributions.
150 | 
151 |    6. Trademarks. This License does not grant permission to use the trade
152 |       names, trademarks, service marks, or product names of the Licensor,
153 |       except as required for reasonable and customary use in describing the
154 |       origin of the Work and reproducing the content of the NOTICE file.
155 | 
156 |    7. Disclaimer of Warranty. Unless required by applicable law or
157 |       agreed to in writing, Licensor provides the Work (and each
158 |       Contributor provides its Contributions) on an "AS IS" BASIS,
159 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
160 |       implied, including, without limitation, any warranties or conditions
161 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
162 |       PARTICULAR PURPOSE. You are solely responsible for determining the
163 |       appropriateness of using or redistributing the Work and assume any
164 |       risks associated with Your exercise of permissions under this License.
165 | 
166 |    8. Limitation of Liability. In no event and under no legal theory,
167 |       whether in tort (including negligence), contract, or otherwise,
168 |       unless required by applicable law (such as deliberate and grossly
169 |       negligent acts) or agreed to in writing, shall any Contributor be
170 |       liable to You for damages, including any direct, indirect, special,
171 |       incidental, or consequential damages of any character arising as a
172 |       result of this License or out of the use or inability to use the
173 |       Work (including but not limited to damages for loss of goodwill,
174 |       work stoppage, computer failure or malfunction, or any and all
175 |       other commercial damages or losses), even if such Contributor
176 |       has been advised of the possibility of such damages.
177 | 
178 |    9. Accepting Warranty or Additional Liability. While redistributing
179 |       the Work or Derivative Works thereof, You may choose to offer,
180 |       and charge a fee for, acceptance of support, warranty, indemnity,
181 |       or other liability obligations and/or rights consistent with this
182 |       License. However, in accepting such obligations, You may act only
183 |       on Your own behalf and on Your sole responsibility, not on behalf
184 |       of any other Contributor, and only if You agree to indemnify,
185 |       defend, and hold each Contributor harmless for any liability
186 |       incurred by, or claims asserted against, such Contributor by reason
187 |       of your accepting any such warranty or additional liability.
188 | 
189 |    END OF TERMS AND CONDITIONS
