If you have made a 461 | custom system off this one, please review the `nerves_system_br v1.17.0` release 462 | notes. 463 | 464 | * Updated dependencies 465 | * [nerves_system_br v1.17.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.17.0) 466 | * [Buildroot 2021.08](http://lists.busybox.net/pipermail/buildroot/2021-September/622072.html) 467 | * [Erlang/OTP 24.1](https://erlang.org/download/OTP-24.1.README) 468 | 469 | ## v1.16.2 470 | 471 | This release updates Erlang/OTP from 24.0.3 to 24.0.5 and Buildroot from 2021.05 472 | to 2021.05.1. Both of these are security/bug fix updates. This is expected to be 473 | a safe upgrade from v1.16.1 for all users. 474 | 475 | * Updated dependencies 476 | * [nerves_system_br v1.16.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.1) 477 | * [Erlang/OTP 24.0.5](https://erlang.org/download/OTP-24.0.5.README) 478 | 479 | * Improvements 480 | * Support for the Adafruit Speaker Bonnet (See PR #214 for details) 481 | * Beta support for using a `runtime.exs` script for runtime configuration. 482 | * Added a `provision` task to the `fwup.config` to enable re-provisioning a 483 | MicroSD card without changing its contents. 484 | * Adds a default `/etc/sysctl.conf` that enables use of ICMP in Erlang. This 485 | requires `nerves_runtime v0.11.5` or later to automatically load the sysctl 486 | variables. With it using `:gen_udp` to send/receive ICMP will "just work". 487 | It also makes it easier to add other sysctl variables if needed. 488 | 489 | ## v1.16.1 490 | 491 | This release updates Nerves Toolchains to v1.4.3 and OTP 24.0.3. It should be safe for everyone to apply. 492 | 493 | * Updated dependencies 494 | * [nerves_system_br v1.16.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.1) 495 | * [Erlang/OTP 24.0.3](https://erlang.org/download/OTP-24.0.3.README) 496 | * [nerves toolchains v1.4.3](https://github.com/nerves-project/toolchains/releases/tag/v1.4.3) 497 | 498 | ## v1.16.0 499 | 500 | This release updates to Buildroot 2021.05 and OTP 24.0.2. If you have made a 501 | custom system off this one, please review the `nerves_system_br v1.16.0` release 502 | notes. 503 | 504 | * Updated dependencies 505 | * [nerves_system_br v1.16.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.16.0) 506 | * [Buildroot 2021.05](http://lists.busybox.net/pipermail/buildroot/2021-June/311946.html) 507 | * [Erlang/OTP 24.0.2](https://erlang.org/download/OTP-24.0.2.README) 508 | 509 | * Improvements 510 | * This release now contains debug symbols and includes the Build-ID in the 511 | ELF headers. This makes it easier to get stack traces from C programs. As 512 | before, the Nerves tooling strips all symbols from firmware images, so this 513 | won't make programs bigger. 514 | * Enable compile-time `wpa_supplicant` options to support WPA3, mesh 515 | networking, WPS and autoscan. 516 | 517 | ## v1.15.1 518 | 519 | This is a security/bug fix release that updates to Buildroot 2021.02.1 and OTP 520 | 23.3.1. It should be safe for everyone to apply. 521 | 522 | * Improvements 523 | * espeak has been removed from the default install to trim 13 MB off the root 524 | filesystem 525 | 526 | * Updated dependencies 527 | * [nerves_system_br v1.15.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.15.1) 528 | * [Buildroot 2021.02](http://lists.busybox.net/pipermail/buildroot/2021-April/307970.html) 529 | * [Erlang/OTP 23.3.1](https://erlang.org/download/OTP-23.3.1.README) 530 | 531 | ## v1.15.0 532 | 533 | This release updates to Buildroot 2021.02 and OTP 23.2.7. If you have made a 534 | custom system off this one, please review the `nerves_system_br v1.15.0` release 535 | notes. 536 | 537 | The Nerves toolchain has also been updated to v1.4.2. This brings in Linux 4.14 538 | headers to enable use of cdev and eBPF. This won't affect most users. 539 | 540 | * Updated dependencies 541 | * [nerves_system_br v1.15.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.15.0) 542 | * [Buildroot 2021.02](http://lists.busybox.net/pipermail/buildroot/2021-March/305168.html) 543 | * [Erlang/OTP 23.2.7](https://erlang.org/download/OTP-23.2.7.README) 544 | * [nerves toolchains v1.4.2](https://github.com/nerves-project/toolchains/releases/tag/v1.4.2) 545 | 546 | ## v1.14.1 547 | 548 | This is a patch release for v1.14.0 which fixes the ABI spec passed for zigler. 549 | 550 | * Improvements 551 | * A few unused directories in `/etc` have been removed. These primarily were 552 | network initialization script directories that aren't used on Nerves, but 553 | were provided by default by Buildroot. 554 | 555 | ## v1.14.0 556 | 557 | This release updates to Buildroot 2020.11.2, GCC 10.2 and OTP 23.2.4. 558 | 559 | When migrating custom systems based, please be aware of the following important 560 | changes: 561 | 562 | * There's a new `getrandom` syscall that is made early in BEAM startup. This 563 | blocks the BEAM before `rngd` can be started to provide entropy. The 564 | workaround is to start `rngd` from `erlinit`. See `erlinit.config`. 565 | * Hardware float is enabled (`eabihf`). If you have pre-built binaries, you will 566 | need to compile them since previous `eabi` was used. 567 | * The GCC 10.2.0 toolchain has a different name that calls out "nerves" as the 568 | vendor and the naming is now more consistent with other toolchain providers. 569 | * Experimental support for tooling that requires more information about the 570 | target has been added. The initial support focuses on zigler. 571 | 572 | * Updated dependencies 573 | * [nerves_system_br: bump to v1.14.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.14.4) 574 | * [Buildroot 2020.11.2](http://lists.busybox.net/pipermail/buildroot/2021-January/302574.html) 575 | * [Erlang/OTP 23.2.4](https://erlang.org/download/OTP-23.2.4.README) 576 | * [Nerves toolchains 1.4.1](https://github.com/nerves-project/toolchains/releases/tag/v1.4.1) 577 | 578 | ## v1.13.3 579 | 580 | This is a bug fix release and contains no major changes. 581 | 582 | * Updated dependencies 583 | * [nerves_system_br: bump to v1.13.7](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.7) 584 | * [Erlang/OTP 23.1.5](https://erlang.org/download/OTP-23.1.5.README) 585 | 586 | * Bug fixes 587 | * Support the Raspberry Pi Zero (no W) by including its device tree files 588 | * Add WiFi Firmware configuration for RPi0W to fix kernel warning 589 | 590 | ## v1.13.2 591 | 592 | This release includes a patch release update to 593 | [Buildroot 2020.08.2](http://lists.busybox.net/pipermail/buildroot/2020-November/296830.html). 594 | 595 | * Updated dependencies 596 | * [nerves_system_br: bump to v1.13.5](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.5) 597 | * [erlinit 1.9.0](https://github.com/nerves-project/erlinit/releases/tag/v1.9.0) 598 | 599 | * Improvements 600 | * Switched source for built-in WiFi module firmware. This pulls in newer 601 | firmware versions that were found to fix issues on the Raspberry Pi 4. It 602 | may improve built-in WiFi on other Raspberry Pis. 603 | 604 | ## v1.13.1 605 | 606 | The main change in this release is to bump the Linux kernel to 5.4. This follows 607 | the kernel update in the Raspberry Pi OS. 608 | 609 | If you have based a custom system off of this one, please inspect the 610 | `nerves_defconfig` for WiFi firmware changes. WiFi firmware is no longer being 611 | pulled from the `rpi-wifi-firmware` since that package is out of date. 612 | 613 | * Updated dependencies 614 | * [nerves_system_br: bump to v1.13.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.4) 615 | * [Erlang/OTP 23.1.4](https://erlang.org/download/OTP-23.1.4.README) 616 | * [boardid 1.10.0](https://github.com/nerves-project/boardid/releases/tag/v1.10.0) 617 | 618 | * Improvements 619 | * Enabled reproducible builds in Buildroot to remove some timestamp and build 620 | path differences in firmware images. This helps delta firmware updates. 621 | * The memory cgroup controller is no longer enabled by default. This was an 622 | upstream change. As a result, the memory cgroup directory is no longer 623 | mounted. 624 | 625 | ## v1.13.0 626 | 627 | This release updates to [Buildroot 628 | 2020.08](http://lists.busybox.net/pipermail/buildroot/2020-September/290797.html) and OTP 23.1.1. 629 | 630 | * Updated dependencies 631 | * [nerves_system_br: bump to v1.13.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.13.2) 632 | * [Erlang/OTP 23.1.1](https://erlang.org/download/OTP-23.1.1.README) 633 | * [erlinit 1.8.0](https://github.com/nerves-project/erlinit/releases/tag/v1.8.0) 634 | * [nerves 1.7.0](https://github.com/nerves-project/nerves/releases/tag/v1.7.0) 635 | 636 | * New features 637 | * Added support for updating the root filesystem using firmware patches. 638 | See the [firmware patch docs](https://hexdocs.pm/nerves/experimental-features.html#content) for more information. 639 | 640 | ## v1.12.2 641 | 642 | This release updates to [Buildroot 643 | 2020.05.1](http://lists.busybox.net/pipermail/buildroot/2020-July/287824.html) 644 | and OTP 23.0.3 which are both bug fix releases. 645 | 646 | * Updated dependencies 647 | * [nerves_system_br: bump to v1.12.4](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.12.4) 648 | * [Erlang/OTP 23.0.3](https://erlang.org/download/OTP-23.0.3.README) 649 | * [nerves_heart v0.3.0](https://github.com/nerves-project/nerves_heart/releases/tag/v0.3.0) 650 | 651 | * New features 652 | * The `/data` directory now exists for storing application-specific data. It 653 | is currently a symlink to `/root`. Using `/data` will eventually be 654 | encouraged over `/root` even though currently there is no advantage. This 655 | change makes it possible to start migrating paths in applications and 656 | libraries. 657 | 658 | * Fixes 659 | * Fixed old references to the `-Os` compiler flag. All C/C++ code will default 660 | to using `-O2` now. 661 | 662 | ## v1.12.1 663 | 664 | * Fixes 665 | * Remove `nerves_system_linter` from hex package.

This change had an impact on how 819 | the WiFi regulatory database gets loaded into the kernel. Instead of building it 820 | into the kernel as previously done, the kernel loads it on demand. This requires 821 | that all WiFi drivers be built as kernel modules so that the database isn't 822 | loaded before the root filesystem is mounted. If you made a custom system and 823 | see boot errors about not being able to load the regulatory database, this is 824 | the problem. 825 | 826 | * Updated dependencies 827 | * [nerves_system_br v1.7.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.7.0) 828 | * Linux 4.19.25 with patches from the Raspberry Pi Foundation 829 | 830 | ## v1.6.3 831 | 832 | * Updated dependencies 833 | * [nerves_system_br v1.6.8](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.6.8) 834 | * Erlang 21.2.6 835 | 836 | ## v1.6.2 837 | 838 | * Updated dependencies 839 | * [nerves_system_br v1.6.6](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.6.6) 840 | * Erlang 21.2.4 841 | * boardid 1.5.3 842 | 843 | ## v1.6.1 844 | 845 | * Updated dependencies 846 | * [nerves_system_br v1.6.5](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.6.5) 847 | * Erlang 21.2.2 848 | * boardid 1.5.2 849 | * erlinit 1.4.9 850 | * OpenSSL 1.1.1a 851 | * Linux 4.14.89 with patches from the Raspberry Pi Foundation 852 | 853 | * Enhancements 854 | * Moved boardid config from inside erlinit.config to /etc/boardid.config 855 | * Compile gpiomem into the Linux kernel 856 | * Enable pstore, an in-memory buffer that can capture logs, kernel 857 | oops and other information when unexpected reboots. The buffer can be 858 | recovered on the next boot where it can be inspected. 859 | 860 | ## v1.6.0 861 | 862 | This pulls in a pending patch in Buildroot to update the version of 863 | OpenSSL from 1.0.2 to 1.1.0h. This fixes what appears to be issues with 864 | Erlang using OpenSSL engines. It also enables Erlang crypto algorithms 865 | such as ed25519 that have been added in recent Erlang releases. 866 | 867 | * Updated dependencies 868 | * [nerves_system_br v1.6.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.6.1) 869 | * Erlang 21.2 870 | * Added dependencies 871 | * wpa_passphrase 872 | * libp11 0.4.9 873 | 874 | ## v1.5.1 875 | 876 | * Updated dependencies 877 | * [nerves_system_br v1.5.3](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.5.3) 878 | 879 | ## v1.5.0 880 | 881 | This release updates the Linux kernel from 4.4 to 4.14.71. 882 | 883 | * Enhancements 884 | * Added Alsa utils `aplay` and `amixer` for audio support. 885 | * Added `espeak` a speech synthesizer for text to audio. 886 | * Automatically reboot if the Linux kernel panics (defaults to a 10 second 887 | delay before the reboot) 888 | 889 | * Updated dependencies 890 | * [nerves_system_br v1.5.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.5.2) 891 | * Linux 4.14.71 with patches from the Raspberry Pi Foundation 892 | * Erlang 21.0.9 893 | 894 | ## v1.4.0 895 | 896 | This release contains various updates to provisioning variables and data. 897 | 898 | **Host requirements** 899 | 900 | Building firmware using this system requires `fwup` to be updated on your 901 | host computer to at least `v1.2.5`. The target minimum version requirement 902 | has not changed from `0.15.0`. 903 | 904 | **Serial numbers** 905 | 906 | Device serial numbers are now set using `NERVES_SERIAL_NUMBER` instead of 907 | `SERIAL_NUMBER`. This is to reduce ambiguity on the source of the serial 908 | by name spacing it along side other Nerves variables. The U-Boot environment 909 | key has also changed from `serial_number` to `nerves_serial_number`. The 910 | erlinit.config has been updated to provide backwards compatibility for setting 911 | the hostname from the serial number by checking for `nerves_serial_number` 912 | and falling back to `serial_number`. 913 | 914 | **Custom provisioning** 915 | 916 | Provisioning data is applied at the time of calling the `fwup` task `complete`. 917 | The `complete` task is executed when writing the firmware to the target disk. 918 | During this time, `fwup` will include the contents of a provisioning file 919 | located at `${NERVES_SYSTEM}/images/fwup_include/provisioning.conf`. By default, 920 | this file only sets `nerves_serial_number`. You can add additional provisioning 921 | data by overriding the location of this file to include your own by setting 922 | the environment variable `NERVES_PROVISIONING`. If you override this variable 923 | you will be responsible for also setting `nerves_serial_number`. 924 | 925 | * Updated dependencies 926 | * [nerves_system_br v1.4.5](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.4.5) 927 | 928 | ## v1.3.0 929 | 930 | This release upgrades gcc from version 6.3.0 to 7.3.0. See the toolchain release 931 | notes for more information. 932 | 933 | * Updated dependencies 934 | * [nerves_system_br v1.4.1](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.4.1) 935 | * [nerves_toolchain_armv6_rpi_linux_gnueabi v1.1.0](https://github.com/nerves-project/toolchains/releases/tag/v1.1.0) 936 | 937 | ## v1.2.1 938 | 939 | * Updated dependencies 940 | * [nerves_system_br v1.3.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.3.2) 941 | 942 | ## v1.2.0 943 | 944 | This release updates Erlang to OTP 21.0 945 | 946 | * Updated dependencies 947 | * [nerves_system_br v1.3.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.3.0) 948 | 949 | ## v1.1.1 950 | 951 | This release fixes some issues and adds firmware UUID support. This support can 952 | be used to unambiguously know what's running on a device. 953 | 954 | * Updated dependencies 955 | * [nerves_system_br v1.2.2](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.2.2) 956 | 957 | * Bug fixes 958 | * Empty serial numbers stored in the U-Boot environment would be used instead 959 | of reverting to devices IDs built into the CPU or board. 960 | * It wasn't possible to enable QtWebEngine (needed for kiosk apps) 961 | 962 | ## v1.1.0 963 | 964 | This release adds official support for provisioning serial numbers to devices. 965 | Other information can be provisioned in a similar manner. See the README.md for 966 | details. 967 | 968 | Buildroot was also updated to 2018.05. Be sure to review the `nerves_system_br` 969 | link for the changes in the embedded Linux components. 970 | 971 | * Updated dependencies 972 | * [nerves_system_br v1.2.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.2.0) 973 | 974 | * New features 975 | * More `wpa-supplicant` features were enabled to support more WiFi use-cases 976 | 977 | ## v1.0.0 978 | 979 | * Updated dependencies 980 | * [nerves_system_br v1.0.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.0.0) 981 | * [nerves_toolchain v1.0.0](https://github.com/nerves-project/toolchains/releases/tag/v1.0.0) 982 | * [nerves v1.0.0](https://github.com/nerves-project/nerves/releases/tag/1.0.0) 983 | 984 | ## v1.0.0-rc.0 985 | 986 | * Updated dependencies 987 | * [nerves_system_br v1.0.0-rc.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v1.0.0-rc.0) 988 | * [nerves_toolchain v1.0.0-rc.0](https://github.com/nerves-project/toolchains/releases/tag/v1.0.0-rc.0) 989 | * [nerves v1.0.0-rc.0](https://github.com/nerves-project/nerves/releases/tag/1.0.0-rc.0) 990 | 991 | ## v0.20.0 992 | 993 | * Updated dependencies 994 | * [nerves_system_br v0.17.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v0.17.0) 995 | * [nerves_toolchain v0.13.0](https://github.com/nerves-project/toolchains/releases/tag/v0.13.0) 996 | * [nerves v0.9.0](https://github.com/nerves-project/nerves/releases/tag/v0.9.0) 997 | 998 | ## v0.19.1 999 | 1000 | * Updated dependencies 1001 | * [nerves_system_br v0.16.3](https://github.com/nerves-project/nerves_system_br/releases/tag/v0.16.3) 1002 | This fixes the call to otp_build so that it always uses Buildroot's version 1003 | the autoconf tools. 1004 | 1005 | ## v0.19.0 1006 | 1007 | * Updated dependencies 1008 | * [nerves_system_br v0.16.1-2017-11](https://github.com/nerves-project/nerves_system_br/releases/tag/v0.16.1-2017-11) 1009 | 1010 | * Enhancements 1011 | * Support for Raspberry Pi 0W 1012 | This is useful if you want to run the USB port in host mode. 1013 | nerves_system_rpi0 is biased to running it in gadget mode and lacks many 1014 | of the USB host drivers and options. 1015 | * Reboot automatically if Erlang VM exits - This is consistent with other 1016 | Nerves systems. See rootfs_overlay/etc/erlinit.config if undesired. 1017 | * Start running nerves_system_linter to check for configuration errors. 1018 | * Disable console blanking for HDMI to make it easier to capture error messages. 1019 | * Automount the boot partition readonly at `/boot` 1020 | * Support for reverting firmware. 1021 | 1022 | See [Reverting Firmware](https://hexdocs.pm/nerves_runtime/readme.html#reverting-firmware) for more info on reverting firmware. 1023 | 1024 | See [fwup-revert.conf](https://github.com/nerves-project/nerves_system_rpi/blob/master/fwup-revert.conf) for more information on how fwup handles reverting. 1025 | 1026 | ## v0.18.0 1027 | 1028 | * Updated dependencies 1029 | * [nerves_system_br v0.15.0](https://github.com/nerves-project/nerves_system_br/releases/tag/v0.15.0) 1030 | * [toolchain v0.12.1](https://github.com/nerves-project/toolchains/releases/tag/v0.12.1) 1031 | 1032 | * Enhancements 1033 | * Support for nerves 0.8.

The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses. 8 | 9 | Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC-licensed material, or material used under an exception or limitation to copyright. More considerations for licensors. 10 | 11 | Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor’s permission is not necessary for any reason–for example, because of any applicable exception or limitation to copyright–then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable. More considerations for the public. 12 | 13 | Creative Commons Attribution 4.0 International Public License 14 | 15 | By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions. 16 | 17 | Section 1 – Definitions. 18 | 19 | a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image. 20 | 21 | b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License. 22 | 23 | c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights. 24 | 25 | d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements. 26 | 27 | e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material. 28 | 29 | f.

Licensor means the individual(s) or entity(ies) granting rights under this Public License. 34 | 35 | i. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them. 36 | 37 | j. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world. 38 | 39 | k. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning. 40 | 41 | Section 2 – Scope. 42 | 43 | a. License grant. 44 | 45 | 1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to: 46 | 47 | A. reproduce and Share the Licensed Material, in whole or in part; and 48 | 49 | B. produce, reproduce, and Share Adapted Material. 50 | 51 | 2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions. 52 | 53 | 3. Term. The term of this Public License is specified in Section 6(a). 54 | 55 | 4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material. 56 | 57 | 5. Downstream recipients. 58 | 59 | A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License. 60 | 61 | B. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material. 62 | 63 | 6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i). 64 | 65 | b. Other rights. 66 | 67 | 1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise. 68 | 69 | 2. Patent and trademark rights are not licensed under this Public License. 70 | 71 | 3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties. 72 | 73 | Section 3 – License Conditions. 74 | 75 | Your exercise of the Licensed Rights is expressly made subject to the following conditions. 76 | 77 | a. Attribution. 78 | 79 | 1. If You Share the Licensed Material (including in modified form), You must: 80 | 81 | A. retain the following if it is supplied by the Licensor with the Licensed Material: 82 | 83 | i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated); 84 | 85 | ii. a copyright notice; 86 | 87 | iii. a notice that refers to this Public License; 88 | 89 | iv. a notice that refers to the disclaimer of warranties; 90 | 91 | v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable; 92 | 93 | B. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and 94 | 95 | C. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License. 96 | 97 | 2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information. 98 | 99 | 3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable. 100 | 101 | 4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License. 102 | 103 | Section 4 – Sui Generis Database Rights. 104 | 105 | Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material: 106 | 107 | a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database; 108 | 109 | b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and 110 | 111 | c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database. 112 | For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights. 113 | 114 | Section 5 – Disclaimer of Warranties and Limitation of Liability. 115 | 116 | a. Unless otherwise separately undertaken by the Licensor, to the extent possible, the Licensor offers the Licensed Material as-is and as-available, and makes no representations or warranties of any kind concerning the Licensed Material, whether express, implied, statutory, or other. This includes, without limitation, warranties of title, merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable. Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You. 117 | 118 | b. To the extent possible, in no event will the Licensor be liable to You on any legal theory (including, without limitation, negligence) or otherwise for any direct, special, indirect, incidental, consequential, punitive, exemplary, or other losses, costs, expenses, or damages arising out of this Public License or use of the Licensed Material, even if the Licensor has been advised of the possibility of such losses, costs, expenses, or damages. Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You. 119 | 120 | c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability. 121 | 122 | Section 6 – Term and Termination. 123 | 124 | a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically. 125 | 126 | b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates: 127 | 128 | 1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or 129 | 130 | 2. upon express reinstatement by the Licensor. 131 | 132 | c. For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License. 133 | 134 | d. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License. 135 | 136 | e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. 137 | 138 | Section 7 – Other Terms and Conditions. 139 | 140 | a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed. 141 | 142 | b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License. 143 | 144 | Section 8 – Interpretation. 145 | 146 | a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License. 147 | 148 | b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions. 149 | 150 | c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor. 151 | 152 | d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority. 153 | 154 | Creative Commons is not a party to its public licenses. Notwithstanding, Creative Commons may elect to apply one of its public licenses to material it publishes and in those instances will be considered the “Licensor.” Except for the limited purpose of indicating that material is shared under a Creative Commons public license or as otherwise permitted by the Creative Commons policies published at creativecommons.org/policies, Creative Commons does not authorize the use of the trademark “Creative Commons” or any other trademark or logo of Creative Commons without its prior written consent including, without limitation, in connection with any unauthorized modifications to any of its public licenses or any other arrangements, understandings, or agreements concerning use of licensed material.

When You Distribute or Publicly 175 | Perform the Work, You may not impose any effective technological 176 | measures on the Work that restrict the ability of a recipient of the 177 | Work from You to exercise the rights granted to that recipient under 178 | the terms of the License. This Section 4(a) applies to the Work as 179 | incorporated in a Collection, but this does not require the Collection 180 | apart from the Work itself to be made subject to the terms of this 181 | License. If You create a Collection, upon notice from any Licensor You 182 | must, to the extent practicable, remove from the Collection any credit 183 | as required by Section 4(c), as requested. If You create an 184 | Adaptation, upon notice from any Licensor You must, to the extent 185 | practicable, remove from the Adaptation any credit as required by 186 | Section 4(c), as requested. 187 | b. You may Distribute or Publicly Perform an Adaptation only under the 188 | terms of: (i) this License; (ii) a later version of this License with 189 | the same License Elements as this License; (iii) a Creative Commons 190 | jurisdiction license (either this or a later license version) that 191 | contains the same License Elements as this License (e.g., 192 | Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible 193 | License. If you license the Adaptation under one of the licenses 194 | mentioned in (iv), you must comply with the terms of that license. If 195 | you license the Adaptation under the terms of any of the licenses 196 | mentioned in (i), (ii) or (iii) (the "Applicable License"), you must 197 | comply with the terms of the Applicable License generally and the 198 | following provisions: (I) You must include a copy of, or the URI for, 199 | the Applicable License with every copy of each Adaptation You 200 | Distribute or Publicly Perform; (II) You may not offer or impose any 201 | terms on the Adaptation that restrict the terms of the Applicable 202 | License or the ability of the recipient of the Adaptation to exercise 203 | the rights granted to that recipient under the terms of the Applicable 204 | License; (III) You must keep intact all notices that refer to the 205 | Applicable License and to the disclaimer of warranties with every copy 206 | of the Work as included in the Adaptation You Distribute or Publicly 207 | Perform; (IV) when You Distribute or Publicly Perform the Adaptation, 208 | You may not impose any effective technological measures on the 209 | Adaptation that restrict the ability of a recipient of the Adaptation 210 | from You to exercise the rights granted to that recipient under the 211 | terms of the Applicable License. This Section 4(b) applies to the 212 | Adaptation as incorporated in a Collection, but this does not require 213 | the Collection apart from the Adaptation itself to be made subject to 214 | the terms of the Applicable License. 215 | c. If You Distribute, or Publicly Perform the Work or any Adaptations or 216 | Collections, You must, unless a request has been made pursuant to 217 | Section 4(a), keep intact all copyright notices for the Work and 218 | provide, reasonable to the medium or means You are utilizing: (i) the 219 | name of the Original Author (or pseudonym, if applicable) if supplied, 220 | and/or if the Original Author and/or Licensor designate another party 221 | or parties (e.g., a sponsor institute, publishing entity, journal) for 222 | attribution ("Attribution Parties") in Licensor's copyright notice, 223 | terms of service or by other reasonable means, the name of such party 224 | or parties; (ii) the title of the Work if supplied; (iii) to the 225 | extent reasonably practicable, the URI, if any, that Licensor 226 | specifies to be associated with the Work, unless such URI does not 227 | refer to the copyright notice or licensing information for the Work; 228 | and (iv) , consistent with Ssection 3(b), in the case of an 229 | Adaptation, a credit identifying the use of the Work in the Adaptation 230 | (e.g., "French translation of the Work by Original Author," or 231 | "Screenplay based on original Work by Original Author"). The credit 232 | required by this Section 4(c) may be implemented in any reasonable 233 | manner; provided, however, that in the case of a Adaptation or 234 | Collection, at a minimum such credit will appear, if a credit for all 235 | contributing authors of the Adaptation or Collection appears, then as 236 | part of these credits and in a manner at least as prominent as the 237 | credits for the other contributing authors. For the avoidance of 238 | doubt, You may only use the credit required by this Section for the 239 | purpose of attribution in the manner set out above and, by exercising 240 | Your rights under this License, You may not implicitly or explicitly 241 | assert or imply any connection with, sponsorship or endorsement by the 242 | Original Author, Licensor and/or Attribution Parties, as appropriate, 243 | of You or Your use of the Work, without the separate, express prior 244 | written permission of the Original Author, Licensor and/or Attribution 245 | Parties. 246 | d. Except as otherwise agreed in writing by the Licensor or as may be 247 | otherwise permitted by applicable law, if You Reproduce, Distribute or 248 | Publicly Perform the Work either by itself or as part of any 249 | Adaptations or Collections, You must not distort, mutilate, modify or 250 | take other derogatory action in relation to the Work which would be 251 | prejudicial to the Original Author's honor or reputation. Licensor 252 | agrees that in those jurisdictions (e.g. Japan), in which any exercise 253 | of the right granted in Section 3(b) of this License (the right to 254 | make Adaptations) would be deemed to be a distortion, mutilation, 255 | modification or other derogatory action prejudicial to the Original 256 | Author's honor and reputation, the Licensor will waive or not assert, 257 | as appropriate, this Section, to the fullest extent permitted by the 258 | applicable national law, to enable You to reasonably exercise Your 259 | right under Section 3(b) of this License (right to make Adaptations) 260 | but not otherwise. 261 | 262 | 5. Representations, Warranties and Disclaimer 263 | 264 | UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR 265 | OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY 266 | KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, 267 | INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, 268 | FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF 269 | LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, 270 | WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION 271 | OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU. 272 | 273 | 6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE 274 | LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR 275 | ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES 276 | ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS 277 | BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 278 | 279 | 7. Termination 280 | 281 | a. This License and the rights granted hereunder will terminate 282 | automatically upon any breach by You of the terms of this License. 283 | Individuals or entities who have received Adaptations or Collections 284 | from You under this License, however, will not have their licenses 285 | terminated provided such individuals or entities remain in full 286 | compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will 287 | survive any termination of this License. 288 | b. Subject to the above terms and conditions, the license granted here is 289 | perpetual (for the duration of the applicable copyright in the Work). 290 | Notwithstanding the above, Licensor reserves the right to release the 291 | Work under different license terms or to stop distributing the Work at 292 | any time; provided, however that any such election will not serve to 293 | withdraw this License (or any other license that has been, or is 294 | required to be, granted under the terms of this License), and this 295 | License will continue in full force and effect unless terminated as 296 | stated above. 297 | 298 | 8. Miscellaneous 299 | 300 | a. Each time You Distribute or Publicly Perform the Work or a Collection, 301 | the Licensor offers to the recipient a license to the Work on the same 302 | terms and conditions as the license granted to You under this License. 303 | b. Each time You Distribute or Publicly Perform an Adaptation, Licensor 304 | offers to the recipient a license to the original Work on the same 305 | terms and conditions as the license granted to You under this License. 306 | c. If any provision of this License is invalid or unenforceable under 307 | applicable law, it shall not affect the validity or enforceability of 308 | the remainder of the terms of this License, and without further action 309 | by the parties to this agreement, such provision shall be reformed to 310 | the minimum extent necessary to make such provision valid and 311 | enforceable. 312 | d. No term or provision of this License shall be deemed waived and no 313 | breach consented to unless such waiver or consent shall be in writing 314 | and signed by the party to be charged with such waiver or consent. 315 | e. This License constitutes the entire agreement between the parties with 316 | respect to the Work licensed here. There are no understandings, 317 | agreements or representations with respect to the Work not specified 318 | here. Licensor shall not be bound by any additional provisions that 319 | may appear in any communication from You. This License may not be 320 | modified without the mutual written agreement of the Licensor and You. 321 | f. The rights granted under, and the subject matter referenced, in this 322 | License were drafted utilizing the terminology of the Berne Convention 323 | for the Protection of Literary and Artistic Works (as amended on 324 | September 28, 1979), the Rome Convention of 1961, the WIPO Copyright 325 | Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 326 | and the Universal Copyright Convention (as revised on July 24, 1971). 327 | These rights and subject matter take effect in the relevant 328 | jurisdiction in which the License terms are sought to be enforced 329 | according to the corresponding provisions of the implementation of 330 | those treaty provisions in the applicable national law. If the 331 | standard suite of rights granted under applicable copyright law 332 | includes additional rights not granted under this License, such 333 | additional rights are deemed to be included in the License; this 334 | License is not intended to restrict the license of any rights under 335 | applicable law. 336 | 337 | 338 | Creative Commons Notice 339 | 340 | Creative Commons is not a party to this License, and makes no warranty 341 | whatsoever in connection with the Work. Creative Commons will not be 342 | liable to You or any party on any legal theory for any damages 343 | whatsoever, including without limitation any general, special, 344 | incidental or consequential damages arising in connection to this 345 | license. Notwithstanding the foregoing two (2) sentences, if Creative 346 | Commons has expressly identified itself as the Licensor hereunder, it 347 | shall have all rights and obligations of Licensor. 348 | 349 | Except for the limited purpose of indicating to the public that the 350 | Work is licensed under the CCPL, Creative Commons does not authorize 351 | the use by either party of the trademark "Creative Commons" or any 352 | related trademark or logo of Creative Commons without the prior 353 | written consent of Creative Commons. Any permitted use will be in 354 | compliance with Creative Commons' then-current trademark usage 355 | guidelines, as may be published on its website or otherwise made 356 | available upon request from time to time. For the avoidance of doubt, 357 | this trademark restriction does not form part of the License. 358 | 359 | Creative Commons may be contacted at https://creativecommons.org/. 360 | -------------------------------------------------------------------------------- /LICENSES/CC0-1.0.txt: -------------------------------------------------------------------------------- 1 | Creative Commons Legal Code 2 | 3 | CC0 1.0 Universal 4 | 5 | CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE 6 | LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN 7 | ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS 8 | INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES 9 | REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS 10 | PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM 11 | THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED 12 | HEREUNDER. 13 | 14 | Statement of Purpose 15 | 16 | The laws of most jurisdictions throughout the world automatically confer 17 | exclusive Copyright and Related Rights (defined below) upon the creator 18 | and subsequent owner(s) (each and all, an "owner") of an original work of 19 | authorship and/or a database (each, a "Work"). 20 | 21 | Certain owners wish to permanently relinquish those rights to a Work for 22 | the purpose of contributing to a commons of creative, cultural and 23 | scientific works ("Commons") that the public can reliably and without fear 24 | of later claims of infringement build upon, modify, incorporate in other 25 | works, reuse and redistribute as freely as possible in any form whatsoever 26 | and for any purposes, including without limitation commercial purposes. 27 | These owners may contribute to the Commons to promote the ideal of a free 28 | culture and the further production of creative, cultural and scientific 29 | works, or to gain reputation or greater distribution for their Work in 30 | part through the use and efforts of others. 31 | 32 | For these and/or other purposes and motivations, and without any 33 | expectation of additional consideration or compensation, the person 34 | associating CC0 with a Work (the "Affirmer"), to the extent that he or she 35 | is an owner of Copyright and Related Rights in the Work, voluntarily 36 | elects to apply CC0 to the Work and publicly distribute the Work under its 37 | terms, with knowledge of his or her Copyright and Related Rights in the 38 | Work and the meaning and intended legal effect of CC0 on those rights. 39 | 40 | 1. Copyright and Related Rights. A Work made available under CC0 may be 41 | protected by copyright and related or neighboring rights ("Copyright and 42 | Related Rights"). Copyright and Related Rights include, but are not 43 | limited to, the following: 44 | 45 | i. the right to reproduce, adapt, distribute, perform, display, 46 | communicate, and translate a Work; 47 | ii. moral rights retained by the original author(s) and/or performer(s); 48 | iii. publicity and privacy rights pertaining to a person's image or 49 | likeness depicted in a Work; 50 | iv. rights protecting against unfair competition in regards to a Work, 51 | subject to the limitations in paragraph 4(a), below; 52 | v. rights protecting the extraction, dissemination, use and reuse of data 53 | in a Work; 54 | vi. database rights (such as those arising under Directive 96/9/EC of the 55 | European Parliament and of the Council of 11 March 1996 on the legal 56 | protection of databases, and under any national implementation 57 | thereof, including any amended or successor version of such 58 | directive); and 59 | vii. other similar, equivalent or corresponding rights throughout the 60 | world based on applicable law or treaty, and any national 61 | implementations thereof. 62 | 63 | 2. Waiver. To the greatest extent permitted by, but not in contravention 64 | of, applicable law, Affirmer hereby overtly, fully, permanently, 65 | irrevocably and unconditionally waives, abandons, and surrenders all of 66 | Affirmer's Copyright and Related Rights and associated claims and causes 67 | of action, whether now known or unknown (including existing as well as 68 | future claims and causes of action), in the Work (i) in all territories 69 | worldwide, (ii) for the maximum duration provided by applicable law or 70 | treaty (including future time extensions), (iii) in any current or future 71 | medium and for any number of copies, and (iv) for any purpose whatsoever, 72 | including without limitation commercial, advertising or promotional 73 | purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each 74 | member of the public at large and to the detriment of Affirmer's heirs and 75 | successors, fully intending that such Waiver shall not be subject to 76 | revocation, rescission, cancellation, termination, or any other legal or 77 | equitable action to disrupt the quiet enjoyment of the Work by the public 78 | as contemplated by Affirmer's express Statement of Purpose. 79 | 80 | 3. Public License Fallback. Should any part of the Waiver for any reason 81 | be judged legally invalid or ineffective under applicable law, then the 82 | Waiver shall be preserved to the maximum extent permitted taking into 83 | account Affirmer's express Statement of Purpose. In addition, to the 84 | extent the Waiver is so judged Affirmer hereby grants to each affected 85 | person a royalty-free, non transferable, non sublicensable, non exclusive, 86 | irrevocable and unconditional license to exercise Affirmer's Copyright and 87 | Related Rights in the Work (i) in all territories worldwide, (ii) for the 88 | maximum duration provided by applicable law or treaty (including future 89 | time extensions), (iii) in any current or future medium and for any number 90 | of copies, and (iv) for any purpose whatsoever, including without 91 | limitation commercial, advertising or promotional purposes (the 92 | "License"). The License shall be deemed effective as of the date CC0 was 93 | applied by Affirmer to the Work. Should any part of the License for any 94 | reason be judged legally invalid or ineffective under applicable law, such 95 | partial invalidity or ineffectiveness shall not invalidate the remainder 96 | of the License, and in such case Affirmer hereby affirms that he or she 97 | will not (i) exercise any of his or her remaining Copyright and Related 98 | Rights in the Work or (ii) assert any associated claims and causes of 99 | action with respect to the Work, in either case contrary to Affirmer's 100 | express Statement of Purpose. 101 | 102 | 4. Limitations and Disclaimers. 103 | 104 | a. No trademark or patent rights held by Affirmer are waived, abandoned, 105 | surrendered, licensed or otherwise affected by this document. 106 | b. Affirmer offers the Work as-is and makes no representations or 107 | warranties of any kind concerning the Work, express, implied, 108 | statutory or otherwise, including without limitation warranties of 109 | title, merchantability, fitness for a particular purpose, non 110 | infringement, or the absence of latent or other defects, accuracy, or 111 | the present or absence of errors, whether or not discoverable, all to 112 | the greatest extent permissible under applicable law. 113 | c. Affirmer disclaims responsibility for clearing rights of other persons 114 | that may apply to the Work or any use thereof, including without 115 | limitation any person's Copyright and Related Rights in the Work. 116 | Further, Affirmer disclaims responsibility for obtaining any necessary 117 | consents, permissions or other rights required for any use of the 118 | Work. 119 | d. Affirmer understands and acknowledges that Creative Commons is not a 120 | party to this document and has no duty or obligation with respect to 121 | this CC0 or use of the Work. 122 | -------------------------------------------------------------------------------- /LICENSES/GPL-2.0-only.txt: -------------------------------------------------------------------------------- 1 | GNU GENERAL PUBLIC LICENSE 2 | Version 2, June 1991 3 | 4 | Copyright (C) 1989, 1991 Free Software Foundation, Inc. 5 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA 6 | 7 | Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 8 | 9 | Preamble 10 | 11 | The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. 12 | 13 | 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 this service 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. 14 | 15 | To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. 16 | 17 | For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. 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. 18 | 19 | We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. 20 | 21 | Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. 22 | 23 | Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. 24 | 25 | The precise terms and conditions for copying, distribution and modification follow. 26 | 27 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 28 | 29 | 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". 30 | 31 | Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 32 | 33 | 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. 34 | 35 | You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 36 | 37 | 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: 38 | 39 | a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. 40 | 41 | b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. 42 | 43 | c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) 44 | 45 | These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. 46 | 47 | Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. 48 | 49 | In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 50 | 51 | 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: 52 | 53 | a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, 54 | 55 | b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, 56 | 57 | c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) 58 | 59 | The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. 60 | 61 | If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 62 | 63 | 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 64 | 65 | 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 66 | 67 | 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 68 | 69 | 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. 70 | 71 | If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. 72 | 73 | It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. 74 | 75 | This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 76 | 77 | 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 78 | 79 | 9. The Free Software Foundation may publish revised and/or new versions of the 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. 80 | 81 | Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 82 | 83 | 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. 84 | 85 | NO WARRANTY 86 | 87 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 88 | 89 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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. 90 | 91 | END OF TERMS AND CONDITIONS 92 | 93 | How to Apply These Terms to Your New Programs 94 | 95 | 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. 96 | 97 | 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 convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. 98 | 99 | one line to give the program's name and an idea of what it does. Copyright (C) yyyy name of author 100 | 101 | 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 2 of the License, or (at your option) any later version. 102 | 103 | 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.

Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. 112 | 113 | You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: 114 | 115 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. 116 | 117 | signature of Ty Coon, 1 April 1989 Ty Coon, President of Vice 118 | -------------------------------------------------------------------------------- /LICENSES/GPL-2.0-or-later.txt: -------------------------------------------------------------------------------- 1 | GNU GENERAL PUBLIC LICENSE 2 | Version 2, June 1991 3 | 4 | Copyright (C) 1989, 1991 Free Software Foundation, Inc. 5 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA 6 | 7 | Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 8 | 9 | Preamble 10 | 11 | The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. 12 | 13 | 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 this service 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. 14 | 15 | To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. 16 | 17 | For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. 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. 18 | 19 | We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. 20 | 21 | Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. 22 | 23 | Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. 24 | 25 | The precise terms and conditions for copying, distribution and modification follow. 26 | 27 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 28 | 29 | 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". 30 | 31 | Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 32 | 33 | 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. 34 | 35 | You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 36 | 37 | 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: 38 | 39 | a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. 40 | 41 | b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. 42 | 43 | c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) 44 | 45 | These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. 46 | 47 | Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. 48 | 49 | In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 50 | 51 | 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: 52 | 53 | a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, 54 | 55 | b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, 56 | 57 | c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) 58 | 59 | The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. 60 | 61 | If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 62 | 63 | 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 64 | 65 | 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 66 | 67 | 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 68 | 69 | 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. 70 | 71 | If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. 72 | 73 | It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. 74 | 75 | This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 76 | 77 | 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 78 | 79 | 9. The Free Software Foundation may publish revised and/or new versions of the 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. 80 | 81 | Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 82 | 83 | 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. 84 | 85 | NO WARRANTY 86 | 87 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 88 | 89 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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. 90 | 91 | END OF TERMS AND CONDITIONS 92 | 93 | How to Apply These Terms to Your New Programs 94 | 95 | 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. 96 | 97 | To do so, attach the following notices to the program.

See the [Getting started 42 | guide](https://hexdocs.pm/nerves/getting-started.html#creating-a-new-nerves-app) 43 | for more information. 44 | 45 | If you need custom modifications to this system for your device, clone this 46 | repository and update as described in [Making custom 47 | systems](https://hexdocs.pm/nerves/customizing-systems.html). 48 | 49 | ## Supported USB WiFi devices 50 | 51 | The base image includes drivers and firmware for Ralink RT53xx 52 | (`rt2800usb` driver) and RealTek RTL8712U (`r8712u` driver) devices. 53 | 54 | We are still working out which subset of all possible WiFi dongles to 55 | support in our images. At some point, we may have the option to support 56 | all dongles and selectively install modules at packaging time, but until 57 | then, these drivers and their associated firmware blobs add significantly 58 | to Nerves release images. 59 | 60 | If you are unsure what driver your WiFi dongle requires, run Raspbian and 61 | configure WiFi for your device. At a shell prompt, run `lsmod` to see which 62 | drivers are loaded. Running `dmesg` may also give a clue. When using `dmesg`, 63 | reinsert the USB dongle to generate new log messages if you don't see them. 64 | 65 | ## Bluetooth 66 | 67 | [BlueHeronTransportUART](https://github.com/blue-heron/blue_heron_transport_uart) 68 | supports bluetooth on the Pi Zero W using `ttyS0`. 69 | See details 70 | [here](https://github.com/nerves-project/nerves_system_rpi0/issues/224#issuecomment-913799838). 71 | 72 | ## Audio 73 | 74 | The Raspberry Pi has many options for audio output. This system supports the 75 | HDMI and stereo audio jack output. The Linux ALSA drivers are used for audio 76 | output. 77 | 78 | The general Raspberry Pi audio documentation mostly applies to Nerves. For 79 | example, to force audio out the HDMI port, run: 80 | 81 | ```elixir 82 | cmd("amixer cset numid=3 2") 83 | ``` 84 | 85 | Change the last argument to `amixer` to `1` to output to the stereo output jack. 86 | 87 | ## Provisioning devices 88 | 89 | This system supports storing provisioning information in a small key-value store 90 | outside of any filesystem. Provisioning is an optional step and reasonable 91 | defaults are provided if this is missing. 92 | 93 | Provisioning information can be queried using the Nerves.Runtime KV store's 94 | [`Nerves.Runtime.KV.get/1`](https://hexdocs.pm/nerves_runtime/Nerves.Runtime.KV.html#get/1) 95 | function. 96 | 97 | Keys used by this system are: 98 | 99 | Key | Example Value | Description 100 | :--------------------- | :---------------- | :---------- 101 | `nerves_serial_number` | `"12345678"` | By default, this string is used to create unique hostnames and Erlang node names. If unset, it defaults to part of the Raspberry Pi's device ID. 102 | 103 | The normal procedure would be to set these keys once in manufacturing or before 104 | deployment and then leave them alone. 105 | 106 | For example, to provision a serial number on a running device, run the following 107 | and reboot: 108 | 109 | ```elixir 110 | iex> cmd("fw_setenv nerves_serial_number 12345678") 111 | ``` 112 | 113 | This system supports setting the serial number offline. To do this, set the 114 | `NERVES_SERIAL_NUMBER` environment variable when burning the firmware. If you're 115 | programming MicroSD cards using `fwup`, the commandline is: 116 | 117 | ```sh 118 | sudo NERVES_SERIAL_NUMBER=12345678 fwup path_to_firmware.fw 119 | ``` 120 | 121 | Serial numbers are stored on the MicroSD card so if the MicroSD card is 122 | replaced, the serial number will need to be reprogrammed. The numbers are stored 123 | in a U-boot environment block. This is a special region that is separate from 124 | the application partition so reformatting the application partition will not 125 | lose the serial number or any other data stored in this block. 126 | 127 | Additional key value pairs can be provisioned by overriding the default 128 | provisioning.conf file location by setting the environment variable 129 | `NERVES_PROVISIONING=/path/to/provisioning.conf`. The default provisioning.conf 130 | will set the `nerves_serial_number`, if you override the location to this file, 131 | you will be responsible for setting this yourself. 132 | 133 | ## Linux kernel and RPi firmware/userland 134 | 135 | There's a subtle coupling between the `nerves_system_br` version and the Linux 136 | kernel version used here. `nerves_system_br` provides the versions of 137 | `rpi-userland` and `rpi-firmware` that get installed. I prefer to match them to 138 | the Linux kernel to avoid any issues. Unfortunately, none of these are tagged by 139 | the Raspberry Pi Foundation so I either attempt to match what's in Raspbian or 140 | take versions of the repositories that have similar commit times. 141 | 142 | [Image credit](#fritzing): This image is from the [Fritzing](http://fritzing.org/home/) parts library. 143 | -------------------------------------------------------------------------------- /REUSE.toml: -------------------------------------------------------------------------------- 1 | version = 1 2 | 3 | [[annotations]] 4 | path = [ 5 | ".formatter.exs", 6 | ".github/workflows/ci.yml", 7 | ".gitignore", 8 | "CHANGELOG.md", 9 | "NOTICE", 10 | "REUSE.toml", 11 | "mix.exs", 12 | "mix.lock", 13 | "VERSION" 14 | ] 15 | precedence = "aggregate" 16 | SPDX-FileCopyrightText = "None" 17 | SPDX-License-Identifier = "CC0-1.0" 18 | 19 | [[annotations]] 20 | path = [ 21 | "README.md" 22 | ] 23 | precedence = "aggregate" 24 | SPDX-FileCopyrightText = "2016 Frank Hunleth" 25 | SPDX-License-Identifier = "CC-BY-4.0" 26 | 27 | # Buildroot derived or related files 28 | [[annotations]] 29 | path = [ 30 | "Config.in", 31 | "package/**", 32 | "external.mk", 33 | "nerves_defconfig", 34 | "post-build.sh", 35 | "post-createfs.sh" 36 | ] 37 | precedence = "aggregate" 38 | SPDX-FileCopyrightText = "The Buildroot developers " 39 | SPDX-License-Identifier = "GPL-2.0-or-later" 40 | 41 | # Linux kernel derived or related files 42 | [[annotations]] 43 | path = [ 44 | "linux/*", 45 | "rootfs_overlay/lib/firmware/brcm/brcmfmac43430-sdio.raspberrypi,model-zero-w.txt", 46 | "linux-6.6.defconfig", 47 | "ramoops.dts" 48 | ] 49 | precedence = "override" 50 | SPDX-FileCopyrightText = "Various" 51 | SPDX-License-Identifier = "GPL-2.0-only" 52 | 53 | # Fwup config files 54 | [[annotations]] 55 | path = [ 56 | "fwup-ops.conf", 57 | "fwup.conf", 58 | "fwup_include/*" 59 | ] 60 | precedence = "aggregate" 61 | SPDX-FileCopyrightText = "None" 62 | SPDX-License-Identifier = "CC0-1.0" 63 | 64 | # Various config files 65 | [[annotations]] 66 | path = [ 67 | "busybox.fragment", 68 | "cmdline.txt", 69 | "config.txt", 70 | "rootfs_overlay/etc/boardid.config", 71 | "rootfs_overlay/etc/erlinit.config", 72 | "rootfs_overlay/etc/fw_env.config" 73 | ] 74 | precedence = "aggregate" 75 | SPDX-FileCopyrightText = "None" 76 | SPDX-License-Identifier = "CC0-1.0" 77 | 78 | # https://github.com/fritzing/fritzing-parts/blob/develop/core/Raspberry_Pi_Zero_1.fzp 79 | [[annotations]] 80 | path = [ 81 | "assets/images/raspberry-pi-model-a-plus.png" 82 | ] 83 | precedence = "aggregate" 84 | SPDX-FileCopyrightText = "Fabian Althaus" 85 | SPDX-License-Identifier = "CC-BY-SA-3.0" 86 | -------------------------------------------------------------------------------- /VERSION: -------------------------------------------------------------------------------- 1 | 1.31.0 2 | -------------------------------------------------------------------------------- /assets/images/raspberry-pi-model-a-plus.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/nerves-project/nerves_system_rpi/24e50f541ebf4958ba2f00d9f47c050ef130b24a/assets/images/raspberry-pi-model-a-plus.png -------------------------------------------------------------------------------- /cmdline.txt: -------------------------------------------------------------------------------- 1 | # NOTES: 2 | # 1.
