1 By using this work in any way, you must comply with the following license,
2 version 0.1 or later (see section 6 about future versions).
5 Libre Opera License v.0.1
9 This license basically wraps together a Creative Commons license applying to
10 the score as a narrative work, and a General Public License that applies to the
11 source code behind it.
13 The GNU General Public License, version 3 or later, is reproduced in the
16 The Creative Commons Attribution-NonCommercial-ShareAlike license is
17 reproduced in the PERFORMING document.
21 The "work" means the copyrightable work licensed under this License; the
22 General Public License may refer to it as "the program". The different authors
23 and licensors are listed in the THANKS document, with contact informations.
24 Each licensee (individuals or organizations) is addressed as "you".
26 The "source code" of the work is defined by the General Public License; it
27 means the full machine- and human-readable (where possible) code needed to
28 generate the score and/or any other document or file needed to perform, modify
29 or reproduce the work. In some parts, the General Public License may refer to
30 it as the "Corresponding Source".
32 The "narrative work" means any performance of the work or based on the work,
33 either computer- or human-generated, any media resulting from such a
34 performance, and any use of narrative elements (characters, events, lyrics,
35 dramatic structure). The Creative Commons license refers to it as the "Work".
39 If you want to modify and/or redistribute this work, you must comply with the
40 GNU General Public License, with the following exception:
41 any interpretation of the source code as a narrative work is not regarded as
42 an object-code form of the work, and therefore will be covered by the Creative
43 Commons by-NC-SA license instead of the GPL license.
44 The source code of the work, however, may be compiled, printed and reproduced
45 as a printed score under the terms and conditions of the GPL license.
49 If you want to perform and/or record and/or distribute any recording based on
50 the narrative work, you must comply with the Creative Commons
51 Attribution-NonCommercial-ShareAlike license, with the following exceptions:
52 in addition to the credits specified in section 4(d) of the license, if you
53 publicly perform, or distribute, any media resulting from the narrative work,
54 you must provide in a reasonable manner, either (i) the full machine-readable
55 source code that has been used to generate the score, or (ii) a written document
56 offering full access to the source code at no charge, to the general public.
57 The title of the narrative work may differ from the title of the source code;
58 if so, both titles have to be mentioned whenever the narrative work (or a
59 derived work) it either distributed or publicly performed.
63 Modifying this work is possible in three distinct ways:
65 a. You may use the source code (or parts of the source code) in a completely
66 different work, which must not include any narrative element of the original
67 work; in this case the only license you must comply with is the GPL license, as
68 specified in section 2.
70 b. You may use the source code to produce a modified version of the narrative
71 work (for instance by keeping some characters or events, or by translating text
72 elements); in this case you must comply with the full license, as well as the
73 GPL license and the Creative Commons license it depends on. A copy of all three
74 licenses must be distributed with the work.
76 c. You may use a performance (or a media resulting from a performance) of the
77 narrative work to produce a new work, without modifying its original source
78 code. In this case you must comply with the Creative Commons
79 Attribution-NonCommercial-ShareAlike license, as specified in section 3; if the
80 derivative work includes any other computer-readable elements, you must also
81 provide the corresponding source for these elements, as well as the unmodified
82 source code of the original work.
84 5. Special authorizations
86 As implied by the Berne Convention for the Protection of Literary and Artistic
87 Works, special authorizations can be given by the authors to use this work
88 outside the terms of its license. Such authorizations have to be requested
89 directly from any of the authors, for specific purposes and motivations; such
90 authorizations (if granted) will not change any of the terms of this license,
91 and will remain limited in their extent and implications.
93 6. Future versions of this license
95 The terms specified by this license are valid for as long as the copyright of
96 the work remains applicable in the country where it is read or performed, and
97 therefore no future version of this license will add any obligations to these.
98 If you ever were to find more restrictive terms in a future version, you may
99 use an older version at your convenience. However, later versions may imply
100 additional permissions by specifying less restrictive terms and conditions.
