LICENSE
GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<https://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with

# piterfly licensing and provenance piterfly **1.1.0** is modified SLOOP 2.8.5, based on Felucca by Leo Kuroshita (@kurogedelic), Hügelton Instruments. Its code is **GPL-3.0-only**, except for the components below. Original notices and authorship are retained. **This is a sanitized distribution tree.** Active device icons are GPL-3.0-only, generated from original piterfly geometry in `tools/gen_pixel_icons.py`. The inherited atlas, historical/proposal screenshots and SLOOP artwork whose terms were not established are excluded, together with the inherited Git history. Replacement does not relicense those omitted materials. See [icon rights](docs/ICON-RIGHTS.md), [release contents](docs/RELEASE-1.1.0.md), [notices](THIRD_PARTY_NOTICES.md) and [export provenance](PROVENANCE.md). ## Code and complete source Firmware, HAL, loader, own engine wrappers, tools, web code and tests retain GPL-3.0-only, except as listed below. Full text: [LICENSE](LICENSE). Binary recipients must have the complete corresponding, modifiable source under its applicable licences. A patch or link to unmodified Felucca/SLOOP is not the source of the modified piterfly binary. Preserve notices and identify changes. The local preparation tool builds from a frozen source snapshot and records file hashes, original Git commit, export adaptations, build inputs and output hashes. Its source archive accompanies the local firmware. Release preparation verifies the sealed filesystem inventory without creating a Git repository. The source manifest identifies the original main commit and the exact exported source hashes. ## Components and assets | Component | Licence/status | Evidence and notices | | --- | --- | --- | | Application, HAL, loader and own DSP/wrappers | GPL-3.0-only | Original file headers; LICENSE | | FM6 core, firmware/src/fm6_core.c | Apache-2.0 | Google 2012, Pascal Gauthier 2016–2025; Leo's C port 2026; LICENSES/Apache-2.0-msfa.txt | | PHYS DaisySP port, phys_dsp.c | MIT | Electrosmith / Emilie Gillet; Leo's fixed-point port; LICENSES/MIT-DaisySP.txt and file notice | | PHYS sympathetic strings, phys_symp.c | MIT | Rings, Emilie Gillet 2015; Leo's port; LICENSES/MIT-Rings.txt | | assets/samples-cc0/ | CC0-1.0 | VSCO-2 CE, VCSL, specified Sonic Pi samples; per-file ATTRIBUTION.txt; LICENSES/CC0-1.0.txt | | Optional hip-hop pack, except EPIANO | CC0-1.0 | Versilian/Sonic Pi; pack CREDITS identifies sources | | Optional hip-hop EPIANO, four WAVs | CC-BY-3.0 | Greg Sullivan Wurlitzer EP200 v1.1, mapped by kinwie; retuned, cut and processed by SLOOP; preserve credit, licence URI and adaptation information; LICENSES/CC-BY-3.0.txt | | tools/gen_waves.py AND every sound it generates | CC0-1.0, explicit author dedication | Felucca commit 5738617968a22b5d4c0d3470cfcc95559052f446 covers both script and outputs; audited algorithm matches | | Terminus BDF and converted bitmap/TTF font data | SIL OFL 1.1 | Dimitar Toshkov Zhekov 2020, Terminus 4.48; LICENSES/OFL-1.1-Terminus.txt; conversions stay OFL | | Web Fukiai icon font | MIT | Hügelton 2026 notice and upstream Leo Kuroshita 2024 notice retained in LICENSES/MIT-Fukiai.txt | | Current assets/icons.png device atlas | GPL-3.0-only | Original 86-icon piterfly set; editable generator tools/gen_pixel_icons.py; assets/icons-LICENSE.txt | | Older Felucca atlas and historical screenshots | Excluded from this tree and its history; permission not established | Original reservation retained; docs/ICON-RIGHTS.md | | Inherited SLOOP graphics and pre-replacement proposals | Excluded from this export | PUBLIC_EXPORT.json records exact paths and hashes; authorship remains credited | | piterfly artwork and derived branding | GPL-3.0-only | User owns the artwork and selected GPL on 2026-11-08; assets/piterfly/LICENSE.txt | | FM-1 and D MINI product images in promo/public/products/ | Third-party product-image rights retained; not relicensed under GPL | Source URLs and original image hashes: promo/public/products/SOURCES.md; excluded from firmware source/archive/site | | Three embedded JieLi SDK files | Apache-2.0 | Official tag AC79NN_SDK_V1.2.1_2023-12-13, verified hashes; LICENSES/Apache-2.0-JieLi.txt | The historically mentioned docs/panel.jpg is absent from this checkout. All 16 sampled drum roles in the audited default build use the supplied CC0 recordings. gen_waves.py also provides fallbacks and the optional SLICE demo. No external Roland 808/909 WAV pack was added relative to the SLOOP base. Procedural drum parameter banks do not imply permission to redistribute commercial recordings. Factory FM6 patches are the project's own according to inherited notices. User-imported samples/SysEx are not automatically part of this distribution. CrispyZebra retains its historical GPL credit for PHASE. klattsch (MIT) is credited as a VOICE design reference, with no copied library according to the source notice. ## Original GPL section 7 permission The original notice and conditional additional permission are preserved verbatim in LICENSES/Felucca-legacy-notice.txt. Permission to combine is conditional on following separate asset terms; it does not itself supply the missing old-atlas licence. The later CC0 dedication resolves the generator/sounds case only. This fork does not extend or rewrite the original authors' grant. ## Tools and names The JieLi toolchain, Docker, Python/Pillow and optional regeneration libraries are build tools, not embedded runtime libraries. The linker uses this project's own objects without vendor libc or SDK .a files. The vendor toolchain bundle's redistribution licence was not established and that bundle is not repackaged. The three SDK files actually embedded in .fwsc have verified Apache notices. Bundling Python/Node or a native installer would require their runtime notices. Felucca, Hügelton and SLOOP identify their authors/projects. M-VAVE/FM-1 identify compatible hardware and belong to their owners. piterfly is independent, without endorsement. Copyright licences do not automatically grant trademark rights. Code contributions are GPL-3.0-only unless expressly documented otherwise. Retain earlier notices and describe modifications and dates. No statement here changes rights in privately imported samples, presets or the user's music.
THIRD_PARTY_NOTICES.md
# Third-party notices — piterfly 1.0.1 Modified from SLOOP 2.8.5 (`bac9c05ea7627449405aa10e48da21d75b6c8c56`), based on Felucca by Leo Kuroshita (@kurogedelic), Hügelton Instruments. SLOOP upstream: <https://github.com/isod89/sloop-fm1>. Changes include 24 patterns, 128 song entries, MIDI THRU, live granular inserts, navigation and piterfly branding. Version/build/licensing preparation changes dated 2026-11-08 are identified in the source manifest; inherited notices remain. piterfly arcade artwork is GPL-3.0-only by the owner’s choice on 2026-11-08; see `assets/piterfly/LICENSE.txt`. This index does not replace the full licence texts. The active 86-icon device atlas is original piterfly geometry under GPL-3.0-only (`tools/gen_pixel_icons.py`, `assets/icons-LICENSE.txt`). The restriction on the older atlas and inherited screenshots remains unresolved; those materials and the inherited Git history are excluded from this distribution tree.

PROVENANCE.md
# piterfly — distribution-tree provenance Piterfly 1.1.0 public source export prepared on 2026-11-13. Piterfly 1.0.0 and 1.0.1 remain published unchanged. The maintainer has tested and accepted the 1.1.0 feature set on a physical M-VAVE FM-1. This tree derives from `piotrwozniak/fm1-piterfly`, private source commit `34f12e3c78116b3ded6fb96bad5fb8e04a660613`. That project modifies SLOOP 2.8.5, upstream commit `bac9c05ea7627449405aa10e48da21d75b6c8c56` from <https://github.com/isod89/sloop-fm1>, based on Felucca by Leo Kuroshita (@kurogedelic), Hügelton Instruments. The initial export was a plain source directory, without a Git repository or copied .git. No inherited Git objects, branches, remotes, tags or reflogs are included. This does not change authorship or erase the origin of the code. `PUBLIC_EXPORT.json` records every excluded path and hash, the original hashes and executable bits of retained files, and the exact private origin commit. It contains metadata, not the excluded artwork. The finished release archive's `SOURCE_MANIFEST.json` identifies the final build inputs after the changes below. SOURCE_INPUTS.json records the reviewed source inventory independently of Git. ## Initial distribution adaptations (1.0.0) - Exclude 46 historical artwork/proposal files: inherited SLOOP logos, upstream screenshots, pre-replacement granular proposals and two historical comparisons. - Exclude 15 generated upstream site/firmware files. Rebuild the site from `web/` and firmware from this tree. Do not reuse the old precompiled browser preview. - Keep the dated audit and its raw captures private. Current licence conclusions and the primary evidence links below replace references to those captures. - Replace the two documentation comparisons with schematic legacy layouts rendered by `tools/render_ui_docs.c` using only the current GPL icon atlas. They illustrate step visibility, not an authentic historical device screenshot. Captions in English, Polish and Spanish identify this distinction. - Remove links to excluded artwork without removing feature explanations or credits. - Seal preferred source paths, hashes and executable bits in SOURCE_INPUTS.json, independently of Git. Reject changed/unlisted sources, nested Git metadata, excluded paths and known historical image hashes. Copy only listed documentation images. - Update the distribution notices to distinguish this clean tree from the private historical repository. No licence for excluded material is inferred or granted. The original 1.0.0 export kept firmware, HAL, loader, DSP algorithms, sounds and their build generators unchanged from the origin commit. The 1.0.1 identity-only changes are recorded below; DSP, sound data and flash layout remain unchanged. The GPL SLOOP logo-generation code remains in `tools/gen_logo.py`; the default build uses only its piterfly splash compiler and `assets/piterfly/arcade-source.png`. Old artwork outputs are not shipped. ## Evidence and rights retained - New atlas: commit `27cc86fe8f8bb43a35a6a987d70029515748e743` in the private project; `tools/gen_pixel_icons.py`, `assets/icons-LICENSE.txt`, and `tests/pixel_icons_test.py` provide editable source and reproducibility checks. - piterfly artwork: owner declaration and GPL-3.0-only choice of 2026-11-08 in `assets/piterfly/LICENSE.txt`; `arcade-source.png` is retained. - Historical reservation: `LICENSES/Felucca-legacy-notice.txt`, unchanged. It is preserved as an original notice, not applied to the replacement icon atlas. - Old atlas removal: <https://github.com/hugelton/Felucca/commit/727f272015da26eb2d0291bd652eba28ff57cb37>. - Explicit CC0 dedication for the wave generator AND generated sounds: <https://github.com/hugelton/Felucca/commit/5738617968a22b5d4c0d3470cfcc95559052f446>. - Sample sources: `assets/samples-cc0/ATTRIBUTION.txt`, both sample-pack CREDITS files, `THIRD_PARTY_NOTICES.md` and the full licence texts in `LICENSES/`. - The optional EPIANO files remain CC-BY-3.0, with the Greg Sullivan / kinwie attribution and adaptation information. They are not relabelled CC0 or GPL. - Three Apache-2.0 JieLi SDK package inputs are included in release sources with the pinned tag, hashes and licence. The proprietary-toolchain distribution status remains unestablished; the toolchain itself is not bundled. ## Verification boundary A local clean build, archive inventory and host tests establish technical checks, not hardware timing, power-cut recovery or a new grant from any third-party author. The selected public site base URL is `https://piotrwozniak.github.io/piterfly/`. The offline editor points to that destination. Selecting this URL does not enable GitHub Pages, upload files or change repository visibility. Deployment still requires a separate instruction; see docs/DEPLOYMENT.md. The original private repository is not modified. ## New private source repository On 2026-11-09 the owner requested a new private repository at <https://github.com/piotrwozniak/piterfly>, initialized on `main` with one fresh root commit. No inherited Git objects or history are imported. `PUBLIC_EXPORT.json` records the earlier export operation, before this new repository was initialized. The browser-preview correction is included (also recorded as `dec83e9` in the original private project); all original authorship and licence notices remain. The inventory tool excludes the new root `.git` directory from source archives, and still rejects nested Git metadata and symlinks. `build/`, caches, virtual environments and local dependency directories are ignored by Git. Existing validated firmware/source/licence bundles and checksums stay unchanged under `build/releases/piterfly-1.0.0-validated/` for a later Release; they predate the repository housekeeping changes and are not committed. Re-seal the current sources and rebuild browser audio before preparing any future release bundle. No Release, GitHub Pages deployment or public visibility is enabled by this step. ## Piterfly 1.0.1 identity candidate — 2026-11-09 The local 1.0.1 candidate replaces the shared `FM-1_910` identity with `FM-1_1120101`, checked free using the Firmware Hub submit-page checker. The application, package and `ota-` loader share the product defined in version.h. Updater resume filters now recognize this exact long identity as well as legacy Felucca loaders. Tests cover the 1.0.0/new-loader transition and the reverse path. No storage/data-layout change or audio-engine change accompanies the identity change. See [the 1.0.1 notes](docs/RELEASE-1.0.1.md) for format limits and device qualification still required. Published 1.0.0 tags and assets stay unchanged. ## Piterfly 1.1.0 Seven synth tracks plus drums, FUN9/protocol 17, selective DUCK, measured dual-core granular balancing and native FM-1 documentation are carried from the current development tree. The public identity, updater compatibility, sealed source inventory and exact-release Pages pipeline introduced in 1.0.1 are retained. The USB MIDI names are piterfly and piterfly Update. Promotional media and private development history remain outside the public source export.

# piterfly device icons and excluded artwork Distribution export prepared locally on 2026-11-08 from private main `8d9ac74c4a8b7cac356a850755714dffe0149a87`; see [provenance](../PROVENANCE.md). ## Included atlas: original GPL-3.0-only geometry All 86 device icons in `assets/icons.png` are generated by `tools/gen_pixel_icons.py`. No pixels from the inherited Felucca atlas are loaded by that generator. The replacement was committed as `27cc86f` before the origin main snapshot. - Owner-selected GPL-3.0-only; full notice: `assets/icons-LICENSE.txt`. - Preferred editable source: `tools/gen_pixel_icons.py`; regenerate with Pillow: `python tools/gen_pixel_icons.py assets/icons.png`. - `assets/icons.json` retains all 86 IDs, 12×12 cells and the 3096-byte packed format. - `tests/pixel_icons_test.py` verifies reproduction, coverage, IDs and packing. - Fukiai in the web editor is separate MIT material with its notices retained. ## Excluded historical material The older atlas (Git blob `e1ae8acc572102bc8179a317b5b08f8658a6503b`, SHA-256 `ec703d9bacef2d88656a7a439f6a6e2ab904cd7f245a004c77586d979defb944`), inherited SLOOP logos/screenshots, pre-replacement proposals and the inherited Git history are not included. `PUBLIC_EXPORT.json` lists the exact excluded files and hashes. The historical reservation and conditional section 7 permission remain verbatim in `LICENSES/Felucca-legacy-notice.txt`; replacement does not relicense old assets. Current piterfly screenshots use the replacement atlas. The two comparison images named `layout-*-before.png` are explicitly labelled schematic reconstructions of the legacy step layout, rendered from included source with the new atlas. They are not historical screenshots and do not load old firmware or artwork. No author contact was made and no permission for omitted material is asserted. The dated audit stays in the private repository. Primary evidence links are retained in PROVENANCE.md, including the old-atlas removal and the later CC0 wave-generator dedication. Current build sources and notices remain included.
assets/icons-LICENSE.txt
piterfly device icon atlas SPDX-License-Identifier: GPL-3.0-only assets/icons.png is generated from original pixel geometry in tools/gen_pixel_icons.py. It replaces the older Felucca atlas on the codex/gpl-pixel-icons feature branch. No pixels from that atlas are used. The project owner selected GNU GPL version 3 only for these new icons on 2026-11-08. The full licence is in ../LICENSE. The generator is the preferred source for editing and regenerating the artwork. This grant covers the new atlas and its generated firmware tables. It does not relicense the old atlas in Git history or old documentation screenshots.
assets/piterfly/LICENSE.txt
piterfly arcade logo and branding SPDX-License-Identifier: GPL-3.0-only The project owner declares ownership of arcade-source.png and selected GNU GPL version 3 only on 2026-11-08. This grant also covers the derived arcade-web.png, firmware splash and piterfly PWA branding generated from it. The full licence text is in ../../LICENSE. This grant does not relicense inherited Felucca/SLOOP artwork, fonts, third-party samples or screenshots containing such material.

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.

THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY

CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
CONDITIONS.
1. Definitions
a. "Adaptation" means a work based upon the Work, or upon the Work and
other pre-existing works, such as a translation, adaptation,
derivative work, arrangement of music or other alterations of a
literary or artistic work, or phonogram or performance and includes
cinematographic adaptations or any other form in which the Work may be
recast, transformed, or adapted including in any form recognizably
derived from the original, except that a work that constitutes a
Collection will not be considered an Adaptation for the purpose of
this License. For the avoidance of doubt, where the Work is a musical
work, performance or phonogram, the synchronization of the Work in
timed-relation with a moving image ("synching") will be considered an
Adaptation for the purpose of this License.
b. "Collection" means a collection of literary or artistic works, such as
encyclopedias and anthologies, or performances, phonograms or
broadcasts, or other works or subject matter other than works listed
in Section 1(f) below, which, by reason of the selection and
arrangement of their contents, constitute intellectual creations, in
which the Work is included in its entirety in unmodified form along
with one or more other contributions, each constituting separate and
independent works in themselves, which together are assembled into a
collective whole. A work that constitutes a Collection will not be
considered an Adaptation (as defined above) for the purposes of this
License.
c. "Distribute" means to make available to the public the original and
copies of the Work or Adaptation, as appropriate, through sale or
other transfer of ownership.
d. "Licensor" means the individual, individuals, entity or entities that

e. "Original Author" means, in the case of a literary or artistic work,
the individual, individuals, entity or entities who created the Work
or if no individual or entity can be identified, the publisher; and in
addition (i) in the case of a performance the actors, singers,
musicians, dancers, and other persons who act, sing, deliver, declaim,
play in, interpret or otherwise perform literary or artistic works or
expressions of folklore; (ii) in the case of a phonogram the producer
being the person or legal entity who first fixes the sounds of a
performance or other sounds; and, (iii) in the case of broadcasts, the
organization that transmits the broadcast.
f. "Work" means the literary and/or artistic work offered under the terms
of this License including without limitation any production in the
literary, scientific and artistic domain, whatever may be the mode or
form of its expression including digital form, such as a book,
pamphlet and other writing; a lecture, address, sermon or other work
of the same nature; a dramatic or dramatico-musical work; a
choreographic work or entertainment in dumb show; a musical
composition with or without words; a cinematographic work to which are
assimilated works expressed by a process analogous to cinematography;

art; an illustration, map, plan, sketch or three-dimensional work
relative to geography, topography, architecture or science; a

extent it is protected as a copyrightable work; or a work performed by
a variety or circus performer to the extent it is not otherwise
considered a literary or artistic work.
g. "You" means an individual or entity exercising rights under this
License who has not previously violated the terms of this License with
respect to the Work, or who has received express permission from the
Licensor to exercise rights under this License despite a previous
violation.
h. "Publicly Perform" means to perform public recitations of the Work and
to communicate to the public those public recitations, by any means or
process, including by wire or wireless means or public digital
performances; to make available to the public Works in such a way that
members of the public may access these Works from a place and at a
place individually chosen by them; to perform the Work to the public
by any means or process and the communication to the public of the
performances of the Work, including by public digital performance; to
broadcast and rebroadcast the Work by any means including signs,
sounds or images.
i. "Reproduce" means to make copies of the Work by any means including
without limitation by sound or visual recordings and the right of
fixation and reproducing fixations of the Work, including storage of a
protected performance or phonogram in digital form or other electronic
medium.
2. Fair Dealing Rights. Nothing in this License is intended to reduce,
limit, or restrict any uses free from copyright or rights arising from
limitations or exceptions that are provided for in connection with the
copyright protection under copyright law or other applicable laws.
3. License Grant. Subject to the terms and conditions of this License,
Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
perpetual (for the duration of the applicable copyright) license to
exercise the rights in the Work as stated below:
a. to Reproduce the Work, to incorporate the Work into one or more
Collections, and to Reproduce the Work as incorporated in the
Collections;
b. to create and Reproduce Adaptations provided that any such Adaptation,
including any translation in any medium, takes reasonable steps to
clearly label, demarcate or otherwise identify that changes were made
to the original Work. For example, a translation could be marked "The
original work was translated from English to Spanish," or a
modification could indicate "The original work has been modified.";
c. to Distribute and Publicly Perform the Work including as incorporated
in Collections; and,
d. to Distribute and Publicly Perform Adaptations.
e. For the avoidance of doubt:
i. Non-waivable Compulsory License Schemes. In those jurisdictions in
which the right to collect royalties through any statutory or
compulsory licensing scheme cannot be waived, the Licensor
reserves the exclusive right to collect such royalties for any
exercise by You of the rights granted under this License;
ii. Waivable Compulsory License Schemes. In those jurisdictions in
which the right to collect royalties through any statutory or
compulsory licensing scheme can be waived, the Licensor waives the
exclusive right to collect such royalties for any exercise by You
of the rights granted under this License; and,
iii. Voluntary License Schemes. The Licensor waives the right to
collect royalties, whether individually or, in the event that the
Licensor is a member of a collecting society that administers
voluntary licensing schemes, via that society, from any exercise
by You of the rights granted under this License.
The above rights may be exercised in all media and formats whether now
known or hereafter devised. The above rights include the right to make
such modifications as are technically necessary to exercise the rights in
other media and formats. Subject to Section 8(f), all rights not expressly
granted by Licensor are hereby reserved.
4. Restrictions. The license granted in Section 3 above is expressly made
subject to and limited by the following restrictions:
a. You may Distribute or Publicly Perform the Work only under the terms
of this License. You must include a copy of, or the Uniform Resource
Identifier (URI) for, this License with every copy of the Work You
Distribute or Publicly Perform. You may not offer or impose any terms
on the Work that restrict the terms of this License or the ability of
the recipient of the Work to exercise the rights granted to that
recipient under the terms of the License. You may not sublicense the
Work. You must keep intact all notices that refer to this License and
to the disclaimer of warranties with every copy of the Work You
Distribute or Publicly Perform. When You Distribute or Publicly
Perform the Work, You may not impose any effective technological
measures on the Work that restrict the ability of a recipient of the
Work from You to exercise the rights granted to that recipient under
the terms of the License. This Section 4(a) applies to the Work as
incorporated in a Collection, but this does not require the Collection
apart from the Work itself to be made subject to the terms of this
License. If You create a Collection, upon notice from any Licensor You
must, to the extent practicable, remove from the Collection any credit
as required by Section 4(b), as requested. If You create an
Adaptation, upon notice from any Licensor You must, to the extent
practicable, remove from the Adaptation any credit as required by
Section 4(b), as requested.
b. If You Distribute, or Publicly Perform the Work or any Adaptations or
Collections, You must, unless a request has been made pursuant to
Section 4(a), keep intact all copyright notices for the Work and
provide, reasonable to the medium or means You are utilizing: (i) the
name of the Original Author (or pseudonym, if applicable) if supplied,
and/or if the Original Author and/or Licensor designate another party
or parties (e.g., a sponsor institute, publishing entity, journal) for
attribution ("Attribution Parties") in Licensor's copyright notice,
terms of service or by other reasonable means, the name of such party
or parties; (ii) the title of the Work if supplied; (iii) to the
extent reasonably practicable, the URI, if any, that Licensor
specifies to be associated with the Work, unless such URI does not
refer to the copyright notice or licensing information for the Work;
and (iv) , consistent with Section 3(b), in the case of an Adaptation,
a credit identifying the use of the Work in the Adaptation (e.g.,
"French translation of the Work by Original Author," or "Screenplay
based on original Work by Original Author"). The credit required by
this Section 4 (b) may be implemented in any reasonable manner;
provided, however, that in the case of a Adaptation or Collection, at
a minimum such credit will appear, if a credit for all contributing
authors of the Adaptation or Collection appears, then as part of these
credits and in a manner at least as prominent as the credits for the
other contributing authors. For the avoidance of doubt, You may only
use the credit required by this Section for the purpose of attribution
in the manner set out above and, by exercising Your rights under this
License, You may not implicitly or explicitly assert or imply any
connection with, sponsorship or endorsement by the Original Author,
Licensor and/or Attribution Parties, as appropriate, of You or Your
use of the Work, without the separate, express prior written
permission of the Original Author, Licensor and/or Attribution
Parties.
c. Except as otherwise agreed in writing by the Licensor or as may be
otherwise permitted by applicable law, if You Reproduce, Distribute or
Publicly Perform the Work either by itself or as part of any
Adaptations or Collections, You must not distort, mutilate, modify or
take other derogatory action in relation to the Work which would be
prejudicial to the Original Author's honor or reputation. Licensor
agrees that in those jurisdictions (e.g. Japan), in which any exercise
of the right granted in Section 3(b) of this License (the right to
make Adaptations) would be deemed to be a distortion, mutilation,
modification or other derogatory action prejudicial to the Original
Author's honor and reputation, the Licensor will waive or not assert,
as appropriate, this Section, to the fullest extent permitted by the
applicable national law, to enable You to reasonably exercise Your
right under Section 3(b) of this License (right to make Adaptations)
but not otherwise.
5. Representations, Warranties and Disclaimer
UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
7. Termination
a. This License and the rights granted hereunder will terminate
automatically upon any breach by You of the terms of this License.
Individuals or entities who have received Adaptations or Collections
from You under this License, however, will not have their licenses
terminated provided such individuals or entities remain in full
compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
survive any termination of this License.
b. Subject to the above terms and conditions, the license granted here is
perpetual (for the duration of the applicable copyright in the Work).
Notwithstanding the above, Licensor reserves the right to release the
Work under different license terms or to stop distributing the Work at
any time; provided, however that any such election will not serve to
withdraw this License (or any other license that has been, or is
required to be, granted under the terms of this License), and this
License will continue in full force and effect unless terminated as
stated above.
8. Miscellaneous
a. Each time You Distribute or Publicly Perform the Work or a Collection,
the Licensor offers to the recipient a license to the Work on the same
terms and conditions as the license granted to You under this License.
b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
offers to the recipient a license to the original Work on the same
terms and conditions as the license granted to You under this License.
c. If any provision of this License is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this License, and without further action
by the parties to this agreement, such provision shall be reformed to
the minimum extent necessary to make such provision valid and
enforceable.
d. No term or provision of this License shall be deemed waived and no
breach consented to unless such waiver or consent shall be in writing
and signed by the party to be charged with such waiver or consent.
e. This License constitutes the entire agreement between the parties with
respect to the Work licensed here. There are no understandings,
agreements or representations with respect to the Work not specified
here. Licensor shall not be bound by any additional provisions that
may appear in any communication from You. This License may not be
modified without the mutual written agreement of the Licensor and You.
f. The rights granted under, and the subject matter referenced, in this
License were drafted utilizing the terminology of the Berne Convention
for the Protection of Literary and Artistic Works (as amended on
September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
and the Universal Copyright Convention (as revised on July 24, 1971).
These rights and subject matter take effect in the relevant
jurisdiction in which the License terms are sought to be enforced
according to the corresponding provisions of the implementation of
those treaty provisions in the applicable national law. If the
standard suite of rights granted under applicable copyright law
includes additional rights not granted under this License, such
additional rights are deemed to be included in the License; this
License is not intended to restrict the license of any rights under
applicable law.

LICENSES/CC0-1.0.txt
CC0 1.0 Universal
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator and
subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for the
purpose of contributing to a commons of creative, cultural and scientific
works ("Commons") that the public can reliably and without fear of later
claims of infringement build upon, modify, incorporate in other works, reuse
and redistribute as freely as possible in any form whatsoever and for any
purposes, including without limitation commercial purposes. These owners may
contribute to the Commons to promote the ideal of a free culture and the
further production of creative, cultural and scientific works, or to gain
reputation or greater distribution for their Work in part through the use and
efforts of others.
For these and/or other purposes and motivations, and without any expectation
of additional consideration or compensation, the person associating CC0 with a
Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
and publicly distribute the Work under its terms, with knowledge of his or her
Copyright and Related Rights in the Work and the meaning and intended legal
effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not limited
to, the following:
i. the right to reproduce, adapt, distribute, perform, display, communicate,
and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or likeness
depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data in
a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation thereof,
including any amended or successor version of such directive); and
vii. other similar, equivalent or corresponding rights throughout the world
based on applicable law or treaty, and any national implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention of,
applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
and Related Rights and associated claims and causes of action, whether now
known or unknown (including existing as well as future claims and causes of
action), in the Work (i) in all territories worldwide, (ii) for the maximum
duration provided by applicable law or treaty (including future time
extensions), (iii) in any current or future medium and for any number of
copies, and (iv) for any purpose whatsoever, including without limitation
commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
the Waiver for the benefit of each member of the public at large and to the
detriment of Affirmer's heirs and successors, fully intending that such Waiver
shall not be subject to revocation, rescission, cancellation, termination, or
any other legal or equitable action to disrupt the quiet enjoyment of the Work
by the public as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason be
judged legally invalid or ineffective under applicable law, then the Waiver
shall be preserved to the maximum extent permitted taking into account
Affirmer's express Statement of Purpose. In addition, to the extent the Waiver
is so judged Affirmer hereby grants to each affected person a royalty-free,
non transferable, non sublicensable, non exclusive, irrevocable and
unconditional license to exercise Affirmer's Copyright and Related Rights in
the Work (i) in all territories worldwide, (ii) for the maximum duration
provided by applicable law or treaty (including future time extensions), (iii)
in any current or future medium and for any number of copies, and (iv) for any
purpose whatsoever, including without limitation commercial, advertising or
promotional purposes (the "License"). The License shall be deemed effective as
of the date CC0 was applied by Affirmer to the Work. Should any part of the
License for any reason be judged legally invalid or ineffective under
applicable law, such partial invalidity or ineffectiveness shall not
invalidate the remainder of the License, and in such case Affirmer hereby
affirms that he or she will not (i) exercise any of his or her remaining
Copyright and Related Rights in the Work or (ii) assert any associated claims
and causes of action with respect to the Work, in either case contrary to
Affirmer's express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or warranties
of any kind concerning the Work, express, implied, statutory or otherwise,
including without limitation warranties of title, merchantability, fitness
for a particular purpose, non infringement, or the absence of latent or
other defects, accuracy, or the present or absence of errors, whether or not
discoverable, all to the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without limitation
any person's Copyright and Related Rights in the Work. Further, Affirmer
disclaims responsibility for obtaining any necessary consents, permissions
or other rights required for any use of the Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to this
CC0 or use of the Work.

Copyright (C) 2026 Leo Kuroshita (@kurogedelic), Hügelton Instruments ## What is code (GPL-3.0-only) Every file in this tree that carries an `SPDX-License-Identifier: GPL-3.0-only` header (one source file carries another: `firmware/src/fm6_core.c`, msfa, Apache-2.0, below; the firmware built with it is GPL-3.0-only as a whole): - the firmware: `firmware/` (app, HAL, update loader) - the build script and tools: `build.sh`, `tools/` - the web pages (installer, editor) and their tests: `web/` (not the Fukiai font, below) - the host tests: `tests/` You may use, study, change and share it under the GPL. If you distribute Felucca, or firmware derived from it, you must also give your recipients its complete corresponding source under the same licence. That includes devices that ship with modified Felucca inside. ## Additional permission (GPL-3.0 section 7) As an additional permission under GPL-3.0 section 7, you may combine Felucca, or a work based on it, with the Felucca Assets (above), and convey the combination. This is allowed even though the Felucca Assets are not licensed under the GPL, provided that: - you follow the GPL for every part that is not a Felucca Asset; and - you follow the terms published for the assets. The Felucca Assets are data (wavetables, icons, sample data). They are not program code. A firmware image built from the GPL sources with replacement assets, or with no assets, is entirely governed by the GPL. ## Third-party material | What | Licence | Where | | --- | --- | --- | | Instrument and drum samples (Versilian Studios VSCO-2 CE, VCSL; Sonic Pi: SCRCH) | CC0 1.0 | `assets/samples-cc0/`, provenance in `ATTRIBUTION.txt` there | | Terminus font 8x16: the FM-1's screen (Terminus Bold, ter-u16b, SLOOP 2.6), and the web editor's font (the regular ter-u16n; `tools/gen_webfont.py` makes it a TrueType font inlined in `web/editor.html`) | SIL OFL 1.1 | `assets/fonts/ter-u16b.bdf`, `assets/fonts/ter-u16n.bdf`, `assets/fonts/Terminus-LICENSE.txt` | | Fukiai icon font (Hügelton Instruments), web editor only | MIT | `web/fukiai.ttf`, `web/FUKIAI-LICENSE.txt` | | CrispyZebra by Leo Kuroshita (<https://github.com/hugelton/CrispyZebra>): the PHASE engine's waveforms are a C port of its oscillator | GPL-3.0 | `firmware/src/eng_phase.c` | | klattsch by Tony Gies (<https://github.com/tgies/klattsch>): design reference for the VOICE (formant) engine; no code copied.

By submitting one, you agree that it may be combined with the Felucca Assets under the section 7 permission above. ## Trademarks "Felucca" and "Hügelton Instruments" are names of Hügelton Instruments. "M-VAVE" and "FM-1" are trademarks of their respective owners. Felucca is independent firmware that runs on FM-1 hardware. It is not affiliated with, endorsed by or supported by those owners. ## Radio Felucca never enables the Bluetooth / Wi-Fi radio of the hardware.
