1+ ITU-T software tools General Public License
2+
3+ Terms and conditions
4+
5+ B.1 This License Agreement applies to any module or other work related to the ITU-T Software Tool Library,
6+ and developed by the User's Group on Software Tools. The term "Module", below, refers to any such module
7+ or work, and a "work based on the Module" means either the Module or any work containing the Module or
8+ a portion of it, either verbatim or with modifications. Each licensee is addressed as "you".
9+
10+ B.2 You may copy and distribute verbatim copies of the Module's source code as you receive it, in any
11+ medium, provided that you:
12+ – conspicuously and appropriately publish on each copy an appropriate copyright notice and
13+ disclaimer of warranty;
14+ – keep intact all the notices that refer to this General Public License and to the absence
15+ of any warranty; and
16+ – give any other recipients of the Module a copy of this General Public License along with the Module.
17+
18+ You may charge a fee for the physical act of transferring a copy.
19+
20+ B.3 You may modify your copy or copies of the Module or any portion of it, and copy and distribute
21+ such modifications under the terms of B.1, provided that you also do the following:
22+ • cause the modified files to carry prominent notices stating that you changed the files
23+ and the date of any change; and
24+ • cause the whole of any work that you distribute or publish, that in whole or in part contains
25+ the Module or any part thereof, either with or without modifications, to be licensed at no
26+ charge to all third parties under the terms of this General Public License (except that you
27+ may choose to grant warranty protection to some or all third parties, at your option);
28+ • if the modified module normally reads commands interactively when run, you must cause it,
29+ when started running for such interactive use in the simplest and most usual way, to print
30+ or display an announcement including an appropriate copyright notice and a notice that there
31+ is no warranty (or else, saying that you provide a warranty) and that users may redistribute
32+ the module under these conditions, and telling the user how to view a copy of this
33+ General Public License.
34+
35+ You may charge a fee for the physical act of transferring a copy, and you may at your option
36+ offer warranty protection in exchange for a fee.
37+
38+ Mere aggregation of another independent work with the Module (or its derivative) on a volume
39+ of a storage or distribution medium does not bring the other work under the scope of these terms.
40+
41+ B.4 You may copy and distribute the Module (or a portion or derivative of it, under B.2) in object
42+ code or executable form under the terms of B.1 and B.2, provided that you also do one of the following:
43+ • accompany it with the complete corresponding machine-readable source code, which must be
44+ distributed under the terms of B.1 and B.2; or
45+ • accompany it with a written offer, valid for at least three years, to give any third party
46+ free (except for a nominal charge for the cost of distribution) a complete machine-readable
47+ copy of the corresponding source code, to be distributed under the terms of B.1 and B.2; or
48+ • accompany it with the information you received as to where the corresponding source code may
49+ be obtained. (This alternative is allowed only for non-commercial distribution and only if
50+ you received the module in object code or executable form alone.)
51+
52+ Source code for a work means the preferred form of the work for making modifications to it.
53+ For an executable file, complete source code means all the source code for all modules it contains;
54+ but, as a special exception, it need not include source code for modules which are standard
55+ libraries that accompany the operating system on which the executable file runs, or for standard
56+ header files or definitions files that accompany that operating system.
57+
58+ B.5 You may not copy, modify, sublicense, distribute or transfer the Module except as expressly
59+ provided under this General Public License. Any attempt otherwise to copy, modify, sublicense,
60+ distribute or transfer the Module is void, and will automatically terminate your rights to
61+ use the Module under this License. However, parties who have received copies, or rights to
62+ use copies, from you under this General Public License will not have their licenses terminated
63+ so long as such parties remain in full compliance.
64+
65+ B.6 By copying, distributing or modifying the Module (or any work based on the Module) you
66+ indicate your acceptance of this license to do so, and all its terms and conditions.
67+
68+ B.7 Each time you redistribute the Module (or any work based on the Module), the recipient
69+ automatically receives a license from the original licensor to copy, distribute or modify
70+ the Module subject to these terms and conditions. You may not impose any further restrictions
71+ on the recipients' exercise of the rights granted herein.
72+
73+ B.8 The ITU-T may publish revised and/or new versions of this General Public License from
74+ time to time. Such new versions will be similar in spirit to the present version, but may
75+ differ in detail to address new problems or concerns.
76+
77+ Each version is given a distinguishing version number. If the Module specifies a version
78+ number of the license which applies to it and "any later version", you have the option
79+ of following the terms and conditions either of that version or of any later version
80+ published by the ITU-T. If the Module does not specify a version number of the license,
81+ you may choose any version ever published by the ITU T.
82+
83+ B.9 If you wish to incorporate parts of the Module into other free modules whose distribution
84+ conditions are different, write to the author to ask for permission. For software which
85+ is copyrighted by the ITU-T, write to the ITU-T Secretariat; exceptions may be made for
86+ this. This decision will be guided by the two goals of preserving the free status of
87+ all derivatives of this free software and of promoting the sharing and reuse of
88+ software generally.
89+
90+ B.10 Because the Module is licensed free of charge, there is no warranty for the Module,
91+ to the extent permitted by applicable law. Except when otherwise stated in writing the
92+ copyright holders and/or other parties provide the Module "as is" without warranty of
93+ any kind, either expressed or implied, including, but not limited to, the implied
94+ warranties of merchantability and fitness for a particular purpose. The entire risk as
95+ to the quality and performance of the Module is with you. Should the Module prove
96+ defective, you assume the cost of all necessary servicing, repair or correction.
97+
98+ B.11 In no event unless required by applicable law or agreed to in writing will
99+ any copyright holder, or any other party who may modify and/or redistribute the Module
100+ as permitted above, be liable to you for damages, including any general, special,
101+ incidental or consequential damages arising out of the use or inability to use the
102+ Module (including but not limited to loss of data or data being rendered inaccurate
103+ or losses sustained by you or third parties or a failure of the Module to operate
104+ with any other modules), even if such holder or other party has been advised of
105+ the possibility of such damages.
