+
+Box64 enables running x86_64 Linux programs, including games, on non-x86_64 Linux systems such as Arm (64-bit little-endian host system required).
+
+Check out Box64 in action on YouTube:
+- [MicroLinux](https://www.youtube.com/channel/UCwFQAEj1lp3out4n7BeBatQ)
+- [Pi Labs](https://www.youtube.com/channel/UCgfQjdc5RceRlTGfuthBs7g)
+- [The Byteman](https://www.youtube.com/channel/UCEr8lpIJ3B5Ctc5BvcOHSnA)
+
+Box64 leverages native system libraries (libc, libm, SDL, OpenGL), offering ease of integration and surprising performance in many applications. For performance benchmarks, check [this analysis](https://box86.org/index.php/2021/06/game-performances/).
+
+With DynaRec for ARM64, RV64 and LA64 platforms, Box64 achieves a speed boost 5-10x faster than the interpreter alone. For a deeper look at DynaRec, see [Inner workings](https://box86.org/2021/07/inner-workings-a-high%e2%80%91level-view-of-box86-and-a-low%e2%80%91level-view-of-the-dynarec/).

+
+## 🖥️ Platform Compatibility Notes
+
+Box64 requires 64-bit libraries on the host system, as it directly translates x86_64 function calls. For 32-bit binaries, use Box86.
+
+**Notes** 
+
+1. Box32 mode is in the making, which aims to support 32-bit binaries on Box64, you can enable it at build time, but do not expect everything to work. There is actually a few things that work, many that don't. It's a known issue, no need to create tickets about it for now.
+2. Some installers may default to x86 on 64-bit host OSes, causing compatibility issues. Workaround: Use a fake `uname` that returns "x86_64" for `-m`.
+
+---
+
+## ⚙️ Configuration
+
+Box64 has configuration files located in `/etc/box64.box64rc` and `~/.box64rc`, both formatted as `.ini` files. If you don’t want to use the default `/etc/box64.box64rc` file, copy it to `~/.box64rc` to ensure compatibility.
+
+Settings priority: `~/.box64rc` > `/etc/box64.box64rc` > Command line.
+
+---
+
+## 📄 Additional Platform-Specific Notes
+
+### Unity Game Emulation
+
+- Many Unity games require OpenGL 3+, which may be challenging on ARM/RISC-V SBCs.
+- **Tip for Pi4 and Pi5 Users**: Set `MESA_GL_VERSION_OVERRIDE=3.2` with `BOX64_DYNAREC_STRONGMEM=1` to prevent freezes and enable strong memory mode.
+- **Using Panfrost**: For better compatibility on ARM, enable `PAN_MESA_DEBUG=gl3` to force higher OpenGL profiles. This can help if a game starts but quits unexpectedly before showing any content.
+
+### GTK Programs
+
+Box64 wraps GTK libraries, supporting both gtk2 and gtk3.
+
+### Steam
+
+Steam requires Box86 due to its 32-bit client app, but uses 64-bit local server binaries. Systems with less than 6GB RAM may need a swap file for optimal performance.
+
+### Wine
+
+Box64 supports Wine64 and Proton. For 32-bit components, Box86 is required. Systems with both Box64 and Box86 can run 32- and 64-bit Windows programs.
+
+**Note**: You can use Wine WOW64 build to run x86 Windows programs in Box64-only environments, this is still experimental, but it works in most cases.
+
+### Vulkan
+
+Box64 wraps Vulkan libraries.

+
+## 🖥️ 平台兼容性说明
+
+Box64 直接转换 x86_64 函数调用到本机原生库，因此需要主机系统上的 64 位库。对于 32 位二进制文件，请使用 Box86。
+
+**注意事项**
+
+1. Box32 模式正在制作中，旨在支持 Box64 上运行 32 位二进制文件，敬请期待！
+2. 某些安装程序可能会将 64 位的主机操作系统判定为 x86 导致兼容性问题。解决方法：使用假的 `uname` ，并使它在运行参数为 `-m` 时返回 `x86_64`。
+
+---
+
+## ⚙️ 配置
+
+Box64 的配置文件位于 `/etc/box64.box64rc` 和 `~/.box64rc`，均为 `.ini` 格式的文件。如果您不想使用默认的 `/etc/box64.box64rc` 文件，请将其复制到 `~/.box64rc` 以确保兼容性。
+
+配置项的优先级：`~/.box64rc` > `/etc/box64.box64rc` > 命令行。
+
+---
+
+## 📄 特定平台的其他说明
+
+### Unity 游戏
+- 许多 Unity 游戏需要 OpenGL 3+，这对 ARM/RISC-V SBC 来说可能具有挑战性。
+- **对 Pi4 和 Pi5 用户的提示**：设置 `MESA_GL_VERSION_OVERRIDE=3.2` 和 `BOX64_DYNAREC_STRONGMEM=1` 以防止卡死并启用强内存模式。
+- **Panfrost**：为了在 ARM 上实现更好的兼容性，启用 `PAN_MESA_DEBUG=gl3` 以强制更高的 OpenGL Profile。如果游戏可以启动但在显示任何内容之前意外退出，这个设置可能会有所帮助。
+
+### GTK 程序
+
+Box64 包装了 GTK 库，支持 gtk2 和 gtk3。
+
+### Steam
+
+由于 Steam 客户端应用是 32 位的，需要使用 Box86，但其本地服务器是 64 位的二进制文件。对于内存少于 6GB 的系统，可能需要使用交换文件以获得最佳性能。
+
+### Wine
+
+Box64 支持 Wine64 和 Proton。对于 32 位组件，需要 Box86。配备 Box64 和 Box86 的系统可以运行 32 位和 64 位的 Windows 程序。
+
+**提示**：您可以使用 Wine WOW64 版本在仅限 Box64 的环境中运行 x86 Windows 程序，这项支持仍处于实验阶段，但在大多数情况下都可以工作。
+
+### Vulkan
+
+Box64 包装了 Vulkan 库。

+
+Box64 дозволяє запускати x86_64 Linux програми (наприклад, ігри) на системах Linux відмінних від x86_64, наприклад ARM (хост-система має мати 64-розрядний порядок редагування).
+
+Ви можете знайти багато відео про Box64 в YouTube каналах [MicroLinux](https://www.youtube.com/channel/UCwFQAEj1lp3out4n7BeBatQ), [Pi Labs](https://www.youtube.com/channel/UCgfQjdc5RceRlTGfuthBs7g) або [The Byteman](https://www.youtube.com/channel/UCEr8lpIJ3B5Ctc5BvcOHSnA)
+
+Оскільки Box64 використовує рідні версії деяких «системних» бібліотек, таких як libc, libm, SDL і OpenGL, його легко інтегрувати та використовувати з більшістю програм, а продуктивність у багатьох випадках може бути напрочуд високою. Подивіться на цей стендовий аналіз для прикладу [тут](https://box86.org/index.php/2021/06/game-performances/).
+
+Box64 інтегрується з DynaRec (динамічний рекомпілятор) для платформ ARM64 і RV64 забезпечуючи підвищення швидкості в 5-10 разів, ніж використання лише інтерпретатора. Деякі високорівневі відомості про те, як працює DynaRec, можна знайти [тут](https://box86.org/2021/07/inner-workings-a-high%e2%80%91level-view-of-box86-and-a-low%e2%80%91level-view-of-the-dynarec/).
+
+Деякі внутрішні коди операцій x64 використовують частини «Бібліотеки емулятора Realmode X86», дивіться [x64primop.c](src/emu/x64primop.c) для детальної інформації про авторські права.

+
+Використання
+----
+
+Є кілька змінних середовища для керування поведінкою Box64.
+
+Дивіться [тут](docs/USAGE.md) для перегляду всіх змінних середовища та того, що вони роблять.
+
+Примітка: Dynarec від Box64 використовує механізм із захистом пам’яті та обробником сигналу помилки сегментів для обробки JIT коду. Простіше кажучи, якщо ви хочете використовувати GDB для налагодження запущеної програми, яка використовує JIT-код (наприклад, mono/Unity3D), ви все одно матимете багато «звичайних» помилок сегментів. Пропонується використовувати щось на зразок `handle SIGSEGV nostop` в GDB, щоб не зупинятися на кожній помилці сегмента, і, можливо, поставити точку зупину всередині `my_memprotectionhandler` в `signals.c`, якщо ви хочете перехопити помилки сегментів.

+Історія версій доступна [тут](docs/CHANGELOG.md).

+
+Примітки щодо 32 бітних платформ
+----
+Оскільки Box64 працює шляхом прямого перекладу викликів функцій з x86_64 на хост-систему, хост-система (та, на якій працює Box64) повинна мати 64-розрядні бібліотеки. Box64 не містить 64-біт <-> 32-біт перекладу.
+
+Також розумійте що Box64 запускатиме лише 64-розрядні двійкові Linux файли. Для 32-розрядних двійкових файлів вам потрібен Box86 (з усіма хитрощами з мультиархітектурною системою або корінними правами). Зауважте, що багато інсталяторів (на основі mojo) повертаються до "x86" при виявленні ОС ARM64, і тому намагатимуться використовувати Box86 для налаштування, навіть якщо існує версія x86_64. Ви можете зламати свій шлях за допомогою фальшивого "uname", який повертає "x86_64", коли аргумент "-m"
+
+----
+
+Примітки щодо конфігурації Box64
+----
+
+Обидва файли мають однаковий синтаксис і в основному є файлами ini. Розділ у квадратних дужках визначає назву процесу, а решта — встановлють змінну середовища. Подивіться [використання](USAGE.md), щоб дізнатися, які параметри можна завдати. Box64 поставляється з файлом за замовчуванням, який слід встановити для кращої стабільності. Файл знаходиться в `system/box64.box64rc` і має бути встановлен в `/etc/box64.box64rc`. Якщо з певних причин ви не хочете встановлювати цей файл у `/etc`, принаймні скопіюйте його в `~/.box64rc` або гра може не працювати належним чином. Зауважте, що пріоритетом є: `~/.bashrc` > `/etc/box64.box64rc` > командний рядок
+Таким чином, ваші налаштування в `~/.bashrc` можуть замінити налаштування з вашого командного рядка...
+
+----
+
+Примітки щодо емуляції ігор Unity
+----
+
+Запуск ігор Unity має працювати, але ви також повинні зауважити, що для багатьох ігор Unity3D потрібен OpenGL 3+, який може бути складно забезпечити на ARM SBC (одноплатних комп’ютерах). Крім того, багато нових ігор Unity3D (наприклад, KSP) використовують стиснуті текстури BC7, які не підтримуються багатьма інтегрованими GPU ARM.
+Підказка: на Pi4 і Pi5 використовуйте `MESA_GL_VERSION_OVERRIDE=3.2` з `BOX64_DYNAREC_STRONGMEM=1`, щоб запобігти зависанням і ввімкнути режим сильної пам’яті, і використовуйте Panfrost `PAN_MESA_DEBUG=gl3`, щоб використовувати вищий профіль, якщо гра починається, а потім завершується, перш ніж щось показати.
+
+----
+
+Примітки щодо програм GTK
+----
+
+Бібліотеки GTK2 і GTK3 тепер використовуються в Box64.
+
+----
+
+Примітки щодо Steam
+----
+
+Зауважте, що Steam є гібридом 32-біт / 64-біт. Вам ПОТРІБЕН box86, щоб запустити Steam, оскільки клієнта є 32-розрядною двійковою програмою. Він також використовує 64-розрядні двійкові файли локального сервера, і цей процес steamwebhelper тепер є обов’язковим навіть у «малому режимі». І цей процес з’їсть багато оперативної пам’яті, таким чином машині з 6 Гб оперативної пам’яті знадобиться файл підкачки для використання Steam.
+
+----
+
+Примітки щодо Wine
+----
+
+Wine64 підтримується Box64, Proton теж. Майте на увазі, що 64-розрядний Wine також містить 32-розрядні компоненти щоб мати можливість запускати 32-розрядні програми Windows. Для 32-розрядних програм потрібен Box86, і вони не працюватимуть без нього. У системі, де присутні і працюють Box64, і Box86, 64-розрядне встановлення Wine може запускати як 32-розрядні, так і 64-розрядні програми Windows (просто використовуйте `wine` і `wine64` відповідно).
+Зауважте, що новий 32-бітний PE в 64-бітному процесі, який Wine зараз реалізує у Wine 7+ тепер підтримується, але підтримка є досить молодою тому можуть виникнути деякі проблеми.
+
+----
+
+Примітки щодо Vulkan
+----
+
+Box64 використовує бібліотеки Vulkan, але зауважте що він тестувався з картою AMD Radeon RX550 і драйвером Freedreno, тому деякі розширення можуть бути відсутні залежно від вашої відеокарти.

+box64 (0.3.6) unstable; urgency=low
+
+This version introduces wowbox64.dll for Hangover; the ability to use the Volatile Metadata of Windows executables for x64 wine; and some better x87/SSE/AVX handling
+
+    => WowBox64 can be built directly from Box64 repo, and can be found in the CI artifacts also
+    => it also supports a subset of BOX64_XXXX settings, which can be set from command line or via a setting file ".box64rc" in the Wine prefix home
+    => Volatile Metadata, when present, allows only applying strong memory ordering when needed, as marked by the compiler, giving overall better performances
+    => The precision control bit of x87 is now handled, allowing some older games to run correctly
+    => More work has been done in the handling of precise NaN and Round handling in SSE & AVX opcodes

+box64 (0.3.4) unstable; urgency=low
+
+* This version is Faster and more compatible
+*    => The RV64 backend got faster and more stable, with lots of RVV 1.0 / xThreadVector support to emulate SSE/SSE2+ opcode (no AVX yet)
+*    => On ARM64, Box64 now support more DRM types than before.
+*    => BOX32 can run steam now. At least on ARM64 backend, it's still not working on RV64 and LA64 for now.
+* Please check CHAGELOG.md for more details

+# Bundling x86 Libraries
+
+The script `box64-bundle-x86-libs.sh` is provided to download, extract, and re-bundle x86_64 and x86 libraries for use with Box64/Box32 and Box86. These libraries improve Box emulation. This bundle provides a much smaller size compared to using a full root file system of an operating system.
+
+## Usage
+
+### Administrator
+
+Install required dependencies for the bundle script.
+
+- Debian
+    ```
+    sudo apt-get update
+    sudo apt-get install coreutils curl binutils rpm2cpio tar zstd
+    ```
+- Fedora
+    ```
+    sudo dnf install coreutils curl binutils tar zstd
+    ```
+
+Run `box64-bundle-x86-libs.sh`. This will create two archives:
+- `box64-bundle-x86-libs.tar.gz` = All of the extracted library files in the directory structure of `usr/lib/box64-i386-linux-gnu` and `usr/lib/box64-x86_64-linux-gnu`.
+- `box64-bundle-x86-pkgs.tar.gz` = All of the Linux distribution packages used to extract the library files. This is only created for preservation purposes and is otherwise unused.
+
+Extract the library archive. Box will automatically search these paths for library files to emulate.
+
+```
+sudo tar --extract --file box64-bundle-x86-libs.tar.gz --directory /
+```
+
+### Developer
+
+Add new packages to the `box64-bundle-x86-libs.csv` file in the format of `<PACKAGE_URL>,<SHA256_CHECKSUM>`.
+
+Supported packages:
+- DEB (Debian)
+- EOPKG (Solus)
+- RPM (Fedora)
+- XBPS (Void Linux)
+
+Preference of operating system packages that provide a library:
+1. RPMs from AlmaLinux 9 provide 10 years of updates.
+2. DEBs from Debian 11 provide 5 years of updates.
+3. EOPKG from Solus provide old variants of obscure 32-bit libraries.
+4. XBPS from Void Linux provide updated variants of obscure 32-bit libraries.
+5. Other (whereever a library is packaged)
+
+Some essential library files will never be emulated (only wrapped) and should not be bundled. This includes glibc, OpenGL, Vulkan, and X11/Xorg libraries. The full list can be found [here](https://github.com/ptitSeb/box64/blob/v0.3.2/src/librarian/library.c#L427). Other libraries with lots of dependencies, such as GTK, require all dependencies to be installed for emulation to work. This becomes dependency hell and should be avoided.
+
+For finding package names that contian a specific library file, use the [pkgs.org](https://pkgs.org/) website. Otherwise, use one of these package manager commands on a x86_64 Linux distribution:
+- DEB
+    - `apt-file <LIBRARY_FILE>`
+- EOPKG
+    - Does not support file search. Use pkgs.org instead.
+- RPM
+    - `dnf provides "*/<LIBRARY_FILE>*"`
+- XBPS
+    - `xbps-query --repository --ownedby <LIBRARY_FILE>`
+
+Once the package name is found, find the exact URL for downloading it.
+- DEB = Explore "main" and "contrib". Search for packages with the name "deb11" in it. Use the "amd64.deb" and "i386.deb" packages.
+    - https://archive.debian.org/debian/pool/
+- EOPKG = Use the "`<VERSION>-<RELEASE>-x86_64.eopkg`" and "`32bit-<VERSION>-<RELEASE>-x86_64.eopkg`" packages.
+    - https://cdn.getsol.us/repo/shannon/
+- RPM = Navigate to the "`<MAJOR>.<MINOR>`" version directory first. Then explore "AppStream" and "BaseOS". Use the "x86_64.rpm" and "i686.rpm" packages.
+    - https://repo.almalinux.org/almalinux/
+    - Enterprise Linux (EL) distributions, such as AlamaLinux, sometimes are missing 32-bit packages. Use the Fedora 34 [update](https://archives.fedoraproject.org/pub/archive/fedora/linux/updates/34/Everything/x86_64/Packages/) and [release](https://archives.fedoraproject.org/pub/archive/fedora/linux/releases/34/Everything/x86_64/os/Packages/) archives for compatible packages with EL 9.
+- XBPS = There are too many files in the repository to display on a web browser. Use pkgs.org instead to find the exact URL for downloading it.
+    - https://repo-default.voidlinux.org/current/
+
+Download the package and then find the checksum with the `sha256sum` command.
+
+Major Linux distributions such as AlmaLinux and Debian provide archives of packages. Rolling distributions such as Solus and Void Linux do not. In those cases, use the [Internet Archive](https://web.archive.org/) to archive any rolling release package used by Box by using the "Save Page Now" feature. If the error "Save Page Now browser crashed" appears, it can be safely ignored. The archive will still have been saved.

+v0.3.6
+======
+
+Highlights:
+
+* This version introduces wowbox64.dll for Hangover; the ability to use the Volatile Metadata of Windows executables for x64 wine; and some better x87/SSE/AVX handling
+
+    => WowBox64 can be built directly from Box64 repo, and can be found in the CI artifacts also
+    => it also supports a subset of BOX64_XXXX settings, which can be set from command line or via a setting file ".box64rc" in the Wine prefix home
+    => Volatile Metadata, when present, allows only applying strong memory ordering when needed, as marked by the compiler, giving overall better performances
+    => The precision control bit of x87 is now handled, allowing some older games to run correctly
+    => More work has been done in the handling of precise NaN and Round handling in SSE & AVX opcodes
+
+Version summary:
+    
+* Added/fixed some Syscalls, helping Go programs
+* Wrapper: more functions added, and some fixes too. Vulkan is 1.4 now, among other things
+* Wrapper: Added a few more wrapped libs (like some avcodec and friends)

+
+v0.3.4
+======
+* This version is Faster and more compatible:
+    => The RV64 backend got faster and more stable, with lots of RVV 1.0 / xThreadVector support to emulate SSE/SSE2+ opcode (no AVX yet)
+    => On ARM64, Box64 now support more DRM types than before.
+    => BOX32 can run steam now. At least on ARM64 backend, it's still not working on RV64 and LA64 for now.
+* Added support to emulate Windows Syscall (needs Proton and a 48bits address space for now)
+* Added BOX64_DYNAREC_DIRTY to have a faster (but less safe) way to handle code that write in it's current page
+* Added a few rarely used opcodes
+* Added experimental support for GDBJIT, that allow an x86/x86_64 program to be debugged on ARM/RV64/LA64 platform with x86 regs and opcode view (might generate a lot of file tho)
+* Added support for Perf tools in a similar way if GDBJIT, to have an x86 fine view of the performances
+* Reworked undefined flags for common operations, to be similar to real CPU
+* Reworked cpuid handling, adding BOX64_CPUTYPE support to select Intel/AMD emulation (no 3DNow! support on AMD for now)

+* Dynarec: RV64: More work on using RVV 1.0 and xTheadVector extension to emulate SSE/SSE2+ opcodes
+* Dynarec: RV64: Added informations on flags when building blocks, to be used when a signal happens to rebuild a x86 context more accurate
+* Dynarec: ARM64: Reworked undefined flags for common operations, to be similar to real CPU
+* Dynarec: ARM64: Added informations on flags and xmm/ymm/x87 register when building blocks, to be used when a signal happens to rebuild a x86 context 100% accurate

+Compiling/Installing
+----
+
+If you don't want to compile box64 yourself and prefer to use third-party pre-build version, go to the [end of the document](#pre-build-packages) for alternatives.
+
+You can also generate your own package using the [instructions below](https://github.com/ptitSeb/box64/blob/main/docs/COMPILE.md#debian-packaging). 
+
+Additional installation steps may be necessary when copying only the box64 executable file without running make install in cross-build environments. See [Cross-compiling](https://github.com/ptitSeb/box64/blob/main/docs/COMPILE.md#Cross-compiling)
+
+## Per-platform compiling instructions
+
+### The general approach
+
+```
+git clone https://github.com/ptitSeb/box64
+cd box64
+mkdir build; cd build; cmake .. ${OPTIONS}
+make -j4  
+sudo make install
+```
+If it's the first install, you also need:
+```
+sudo systemctl restart systemd-binfmt
+```
+- You can use `make -j1`, `make -j2` with less jobs to prevent running out of memory
+- You can also add `-DBAD_SIGNAL=ON` to the cmake command if you are on a Linux Kernel mixed with Android, like on RK3588.
+
+### Note about Box32
+
+If you want to build Box64 with the Box32 option, you will need to add `-DBOX32=ON` to the cmake command. That will enable 32bits process to be run with Box64.
+If you also want binfmt integration on 32bits binaries, you also need to add `-DBOX32_BINFMT=ON` to the cmake command.
+
+### Note about WowBox64
+
+A highly experimantal subproject named WowBox64 has been added as a build option, add `-DWOW64=ON` to the cmake command to enable it.
+It will build alongside the regular Box64, and produce a `wowbox64.dll` file in `build/wowbox64-prefix/src/wowbox64-build/` directory.
+
+### Note about binfmt_misc on Android
+
+[binfmt_misc](https://en.wikipedia.org/wiki/Binfmt_misc) is a capability of the Linux kernel which allows arbitrary executable file formats to be recognized and passed to certain user space applications such as Box64 usually used with systemd but systems like Android can't run/use systemd so you will need to register Box64 manually, this will also work inside a CHRoot.
+```
+sudo mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
+sudo echo ':box64:M::\x7fELF\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x3e\x00:\xff\xff\xff\xff\xff\xff\xff\x00\x00\x00\x00\xff\xff\xff\xff\xff\xfe\xff\xff\xff:/usr/local/bin/box64:' | sudo tee /proc/sys/fs/binfmt_misc/register
+```
+
+
+#### Example of generic ARM64 build for linux platforms
+
+```
+git clone https://github.com/ptitSeb/box64
+cd box64
+mkdir build; cd build; cmake .. -D ARM_DYNAREC=ON -D CMAKE_BUILD_TYPE=RelWithDebInfo
+make -j4
+sudo make install
+sudo systemctl restart systemd-binfmt
+```
+
+#### Example of generic ARM64 build for linux platforms with full box32 integration
+
+```
+git clone https://github.com/ptitSeb/box64
+cd box64
+mkdir build; cd build; cmake .. -D ARM_DYNAREC=ON -D CMAKE_BUILD_TYPE=RelWithDebInfo -D BOX32=ON -D BOX32_BINFMT=ON
+make -j4
+sudo make install
+sudo systemctl restart systemd-binfmt

+#### for Raspberry Pi 3
+
+On a 64bit OS:
+
+If building on the Pi, you will also need a large swap (3 GB+)
+[optionally reduce GPU memory to a minimum (e.g. 16 MB) using `raspi-config`
+(and reboot) before starting the build]:
+
+You can use e.g. '`make -j4`' to speed up the build, but on a Pi 3 with 1GB memory you will likely
+run out of memory at some point and need to run the build again.
+Still, this can be faster if your build is attended.

+
+----
+
+### Use ccmake
+
+Alternatively, you can **use the curses-based ccmake (or any other gui frontend for cmake)** to select which platform to use interactively.
+
+### Customize your build
+
+#### Use ccache when present
+
+Add `-DUSE_CCACHE=1` option if you have ccache and plan to touch the sources.
+
+#### Include debug information
+
+Add `-DCMAKE_BUILD_TYPE=RelWithDebInfo` option for an optimized build with debug information embedded. That way, if you want to debug a crash or analyze performance, you have symbols.
+
+#### Build with trace
+
+To have a trace enabled build (***the interpreter will be slightly slower***), add `-DHAVE_TRACE=1`. You will need the [Zydis library](https://github.com/zyantific/zydis) in your `LD_LIBRARY_PATH` or in the system library folders at runtime to get x86 trace. Use version v3.2.1, as later versions have changed the API and no longer work with box64.
+
+#### Build DynaRec
+
+Add `-D ARM_DYNAREC=ON` option to enable DynaRec on ARM machines.  
+Add `-D RV64_DYNAREC=ON` option to enable DynaRec on RV64 machines.  
+Add `-D LARCH64_DYNAREC=ON` option to enable DynaRec on LARCH64 machines.  
+
+#### Save memory at run time
+
+You can use `-DSAVE_MEM` to have a build that will try to save some memory. For now, it only increases the jumptable from 4 levels to 5. The added granularity avoids wasting space, but adds one more read from memory when jumping between blocks.
+
+#### Build outside of a git repo
+
+Box64 uses git SHA1 to show last commit in version number, use `-DNOGIT=1` option when building outside of a git repo (for example, downloading a release source code zip from github).
+
+#### Use faster linker
+
+Add `-DWITH_MOLD=1` option when GNU ld is extremely slow. Then run `mold -run make -j4` to build (make sure [Mold](https://github.com/rui314/mold) is installed).
+
+#### Build a statically linked box64
+
+You can now build box64 statically linked, with `-DSTATICBUILD` to use inside of a x86_64 chroot. Note that this version of box64 will only have the minimal wrapped libs, such as libc, libm and libpthread. Other libs (like libGL or libvulkan, SDL2, etc...) will use x86_64 versions. A static build is intended to be used in a docker image, or in a headless server. It is highly experimental, but feedback is always welcome.
+
+----
+
+## Testing
+
+A few tests are included with box64.
+
+They can be launched using the `ctest` command.
+
+The tests are very basic and only test some functionality for now.
+
+----
+
+## Debian Packaging
+
+Box64 can also be packaged into a .deb file ***using the source code zip from the releases page*** with `DEB_BUILD_OPTIONS=nostrip dpkg-buildpackage -us -uc -nc`. Configure any additional cmake options you want in `debian/rules`.
+
+## Pre-built packages
+
+### Debian-based Linux 
+
+You can use the [Pi-Apps-Coders apt repository](https://github.com/Pi-Apps-Coders/box64-debs) to install precompiled box64 debs, updated every 24 hours. 
+
+```
+# check if .list file already exists

+  sudo rm -f /etc/apt/sources.list.d/box64.list || exit 1
+fi
+
+# check if .sources file already exists
+if [ -f /etc/apt/sources.list.d/box64.sources ]; then

+
+sudo apt update
+sudo apt install box64-generic-arm -y
+```
+
+## Cross-compiling 
+----
+### Set Up the Cross-Compiler
+For example, to compile Box64 for RISC-V on an x86 machine, you can get prebuilt GNU toolchain from the [riscv-gnu-toolchain](https://github.com/riscv-collab/riscv-gnu-toolchain/releases) 
+
+### Run CMake with Cross-Compilation Options 
+Follow the per-platform compilation instructions to configure the CMake options for your target architecture.
+In particular, you must specify the cross-compiler. For example:
+```
+-DCMAKE_C_COMPILER=riscv64-unknown-linux-gnu-gcc  # Or whichever cross-compiler you use
+```
+
+### Running tests with QEMU (optional)
+To do a quick check, run:
+```
+qemu-riscv64 -L path/to/your/riscv64/sysroot box64 --help
+```
+You can run `dirname $(find -name libc.so.6)` to determine whether sysroot is provided by the prebuilt GNU toolchain or not.
+
+To run CTest-based tests under QEMU:
+```
+ctest -j$(nproc)
+```
+
+### Installing on the Target Machine
+After successfully cross-compiling, copy the box64 executable to your RISC-V device. Note that simply copying the binary does not automatically install Box64’s shared libraries. Because `make install` does not run on the target during cross-compilation, libraries required for emulation may be missing.
+
+To fix this, copy the shared libraries folder from the Box64 repository (`x64lib` or `x86lib`) to your target. Place them into the proper library search paths, for example:
+- `/usr/lib/box64-x86_64-linux-gnu/` (for x86_64) 
+- `/usr/lib/box64-i386-linux-gnu/` (for i386)

+Usage
+----
+
+There are many environment variables to control Box64's behaviour, which will be listed below by category.
+
+There are 2 types of Box64 builds: the Wine WOW64 build (WowBox64) and the regular Linux build. Beware only some of the environment variables are available in WowBox64.
+
+### Configuration files
+
+In addition to environment variables, if you're using the regular Linux build, Box64 also looks for 2 places for rcfile by default: the system-wide `/etc/box64.box64rc` and user-specific `~/.box64rc`.
+While in WowBox64, the configuration file is checked at `%USERPROFILE%/.box64rc` only.
+Settings priority follows this order (from highest to lowest): `~/.box64rc` > `/etc/box64.box64rc` > environment variables.
+
+Example configuration:
+
+```
+[factorio]
+BOX64_DYNAREC_SAFEFLAGS=0
+BOX64_DYNAREC_BIGBLOCK=2
+BOX64_DYNAREC_FORWARD=1024
+BOX64_DYNAREC_CALLRET=1
+```
+
+This configuration will apply the specified settings application-wide to any executable named `factorio`.
+
+### Advanced usage for Linux build
+
+1. **Wildcard Matching**
+
+   Asterisks (`*`) can be used for basic pattern matching in application names. For instance, `[*setup*]` will match any program containing "setup" in its name. Note this implements simple wildcard matching rather than full regex support.
+2. **Custom Configuration File**
+
+   The `BOX64_RCFILE` environment variable can specify an alternative configuration file instead of the default `/etc/box64.box64rc`.
+3. **Per-File Settings**
+
+   Sections starting with `/` apply to specific files. For example:
+   ```
+   [/d3d9.dll]
+   BOX64_DYNAREC_SAFEFLAGS=0
+   ```
+   These settings will only affect the `d3d9.dll` file. This syntax also works for **emulated** Linux libraries, e.g., `[/libstdc++.so.6]`.

+# Installing Wine64
+Running Wine64/Wine with Box64/Box86 allows x64/x86 Windows programs to run on 64-bit ARM Linux devices.
+ - Box64 needs `wine-amd64` to be installed **manually** on ARM64 (aarch64) devices.  This will run 64-bit Windows programs (aka x86_64).
+ - Box86 needs `wine-i386` to be installed **manually** on ARM32 (armhf) devices (or on ARM64 with multiarch or chroot).  This will run 32-bit Windows programs (aka x86).
+ - _Note that `wine:arm64` and `wine:armhf` will not work with Box64/Box86. Your device's package manager might try to install those if you ask it to install wine._
+
+See installation steps below (in the [Examples](#examples) section).
+
+## Overview
+The general procedure for installing Wine64 & Wine for Box64 & Box86 is to...
+ - Download all the install files for the version of Wine you wish to install
+ - Unzip or dpkg the install files into one folder
+ - Move that folder to the directory that you wish Wine to run from (often `~/wine/` by default)
+ - Go to `/usr/local/bin` and make symlinks or scripts that will point to your main wine binaries.
+ - Boot wine to create a new wineprefix.
+ - Download winetricks (which is just a complicated bash script), make it executable, then copy it to `/usr/local/bin`.
+
+## Examples
+### Installing Wine64 & Wine for Box64 & Box86 on Raspberry Pi OS from WineHQ .deb files
+_Links from the [WineHQ repo](https://dl.winehq.org/wine-builds/debian/dists/)_
+
+This install method allows you to install different versions of Wine64/Wine.  You may install any version/branch of Wine that you wish.

+
+## Installing winetricks
+Winetricks is a bash script which makes it easier to install & configure any desired Windows core system software packages which may be dependencies for certain Windows programs.  You can either install it with `apt`, or manually using the steps below.
+
+```
+sudo apt-get install cabextract -y                                                                   # winetricks needs this installed
+sudo mv /usr/local/bin/winetricks /usr/local/bin/winetricks-old                                      # Backup old winetricks
+cd ~/Downloads && wget https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks # Download
+sudo chmod +x winetricks && sudo mv winetricks /usr/local/bin/                                       # Install
+```
+
+Whenever we run winetricks, we must tell Box86 to supress its info banner, otherwise winetricks will crash.  Box86's info banner can be suppressed using the `BOX86_NOBANNER=1` environment variable before invoking winetricks (example: `BOX86_NOBANNER=1 winetricks`).
+
+If `apt` installed a desktop menu shortcut for winetricks (or if you make your own desktop shortcut for winetricks) then you may need to edit that shortcut to include Box86's BOX86_NOBANNER=1 env var.  With your favorite text editor, edit `/usr/share/applications/winetricks.desktop` and change `Exec=winetricks --gui` to `Exec=env BOX86_NOBANNER=1 winetricks --gui`.
+
+## Example commands
+Creating a 64-bit wineprefix:
+`wine64 wineboot` or `wine wineboot` (wineprefix is created in `~/.wine/`)
+`WINEPREFIX="$HOME/prefix64" wine wineboot` (wineprefix is created in `~/prefix64/`) _Note: You will need to invoke `WINEPREFIX="$HOME/prefix64"` before every command to use this wineprefix._
+
+Creating a 32-bit wineprefix:
+`WINEARCH=win32 wine wineboot` (wineprefix is created in `~/.wine/`)
+
+Fore-quitting wine:
+`wineserver -k`
+
+Running Wine Configuration:
+`winecfg`
+
+Using winetricks:
+`winetricks -q corefonts vcrun2010 dotnet20sp1`  
+_This command will silently install three packages in series: Windows core fonts, VC++ 2010 Runtimes, and .NET 2.0 SP1.  `-q` is the "install silent/quiet" command._
+
+Invoking Box86's logging features (with `BOX86_LOG=1` or similar) will cause winetricks to crash.
+
+For a list of all the different Windows packages & libraries that winetricks can help you install, run `winetricks list-all`  
+
+## Other notes
+
+### Wineprefixes (and Wine initialization)
+When you first run or boot Wine (`wine wineboot`), Wine will create a new user environment within which to install Windows software.  This user environment is called a "wineprefix" (or "wine bottle") and is located (by default) in `~/.wine` (note that Linux folders with a `.` in front of them are "hidden" folders).  Think of a wineprefix as Wine's virtual 'harddrive' where it installs software and saves settings.  Wineprefixes are portable and deletable.  For more Wine documentation, see [WineHQ](https://www.winehq.org/documentation).
+
+If you at any point corrupt something inside your default wineprefix, you can start "fresh" by deleting your `~/.wine` directory (with the `rm -rf ~/.wine` command) and boot wine again to create a new default wineprefix.
+
+### Transplanting wineprefixes
+If software isn't installing in Wine with Box86, but is installing for you in Wine on a regular x86 Linux computer, you can copy a wineprefix from your x86 Linux computer to the device you're running Box86 on. This is most easily done by tarring the `~/.wine` folder on your x86 Linux computer (`tar -cvf winebottle.tar ~/.wine`), transferring the tar file to your device, then un-tarring the tar file (`tar -xf winebottle.tar`) on your device running Box86 & Wine. Tarring the wineprefix preserves any symlinks that are inside it.
+
+### Swapping out different versions of Wine
+Some versions of Wine work better with certain software. It is best to install a version of Wine that is known to work with the software you would like to run. There are three main development branches of Wine you can pick from, referred to as wine-stable, wine-devel, and wine-staging. _Note that the wine-staging branch requires extra installation steps on Raspberry Pi._
+
+Your entire Wine installation can reside within a single folder on your Linux computer. TwisterOS assumes that your Wine installation is located inside the `~/wine/` directory. The actual directory where you put your `wine` folder doesn't matter as long as you have symlinks within the `/usr/local/bin/` directory which point to the `wine` folder so that Linux can find Wine when you type `wine` into the terminal).
+
+You can change which version of Wine you are running simply by renaming your old `wine` and `.wine` folders to something else, then putting a new `wine` folder (containing your new version of Wine) in its place. Running `wine wineboot` again will migrate a wineprefix from an older version of Wine to be usable by the newer version of Wine you just installed.  You can check which version of Wine you're running with the `wine --version` command.

+=head1 NAME
+
+box64 - Linux Userspace x86_64 Emulator with a twist
+
+=head1 SYNOPSIS
+
+B<box64> [B<--help>] [B<--version>] I<executable>
+
+=head1 DESCRIPTION
+
+B<Box64> lets you run x86_64 Linux programs (such as games) on non-x86_64 Linux
+systems, like ARM (host system needs to be 64-bit little-endian). Since B<Box64>
+uses the native versions of some "system" libraries, like libc, libm, SDL, and
+OpenGL, it's easy to integrate and use with most applications, and performance
+can be surprisingly high in many cases. B<Box64> integrates with DynaRec (dynamic
+recompiler) for the ARM64 platform, providing a speed boost between 5 to 10
+times faster than using only the interpreter.
+
+=head1 OPTIONS

+=item B<-h,--help>
+
+Print box64 help and quit.
+
+=item B<-v,--version>
+
+Print box64 version and quit.
+

+
+=head1 BRIEF USAGE
+
+There are many environment variables to control B<Box64>'s behaviour. In
+addition to environment variables, B<Box64> also looks for 2 places for rcfile:
+F</etc/box64.box64rc> and F<~/.box64rc>, in the format of .ini files.
+Settings priority: F<~/.box64rc> > F</etc/box64.box64rc> > environment variables.

+There are 2 types of Box64 builds: the Wine WOW64 build (WowBox64) and the regular Linux build. Beware only some of the environment variables are available in WowBox64.
+
+### Configuration files
+
+In addition to environment variables, if you're using the regular Linux build, Box64 also looks for 2 places for rcfile by default: the system-wide `/etc/box64.box64rc` and user-specific `~/.box64rc`.
+While in WowBox64, the configuration file is checked at `%USERPROFILE%/.box64rc` only.
+Settings priority follows this order (from highest to lowest): `~/.box64rc` > `/etc/box64.box64rc` > environment variables.
+
+Example configuration:
+
+```
+[factorio]
+BOX64_DYNAREC_SAFEFLAGS=0
+BOX64_DYNAREC_BIGBLOCK=2
+BOX64_DYNAREC_FORWARD=1024
+BOX64_DYNAREC_CALLRET=1
+```
+
+This configuration will apply the specified settings application-wide to any executable named `factorio`.
+
+### Advanced usage for Linux build
+
+1. **Wildcard Matching**
+
+   Asterisks (`*`) can be used for basic pattern matching in application names. For instance, `[*setup*]` will match any program containing "setup" in its name. Note this implements simple wildcard matching rather than full regex support.
+2. **Custom Configuration File**
+
+   The `BOX64_RCFILE` environment variable can specify an alternative configuration file instead of the default `/etc/box64.box64rc`.
+3. **Per-File Settings**
+
+   Sections starting with `/` apply to specific files. For example:
+   ```
+   [/d3d9.dll]
+   BOX64_DYNAREC_SAFEFLAGS=0
+   ```
+   These settings will only affect the `d3d9.dll` file. This syntax also works for **emulated** Linux libraries, e.g., `[/libstdc++.so.6]`.

+=head1 SYNOPSIS
+
+B<box64> [B<--help>] [B<--version>] I<executable>
+
+=head1 DESCRIPTION
+
+B<Box64> lets you run x86_64 Linux programs (such as games) on non-x86_64 Linux
+systems, like ARM (host system needs to be 64-bit little-endian). Since B<Box64>
+uses the native versions of some "system" libraries, like libc, libm, SDL, and
+OpenGL, it's easy to integrate and use with most applications, and performance
+can be surprisingly high in many cases. B<Box64> integrates with DynaRec (dynamic
+recompiler) for the ARM64 platform, providing a speed boost between 5 to 10
+times faster than using only the interpreter.

+
+=head1 BRIEF USAGE
+
+There are many environment variables to control B<Box64>'s behaviour. In
+addition to environment variables, B<Box64> also looks for 2 places for rcfile:
+F</etc/box64.box64rc> and F<~/.box64rc>, in the format of .ini files.
+Settings priority: F<~/.box64rc> > F</etc/box64.box64rc> > environment variables.

+ * double x[],y[]; int e0,nx,prec;
+ *
+ * __rem_pio2_large return the last three digits of N with
+ *              y = x - N*pi/2
+ * so that |y| < pi/2.
+ *
+ * The method is to compute the integer (mod 8) and fraction parts of
+ * (2/pi)*x without doing the full multiplication. In general we
+ * skip the part of the product that are known to be a huge integer (
+ * more accurately, = 0 mod 8 ). Thus the number of operations are
+ * independent of the exponent of the input.
+ *
+ * (2/pi) is represented by an array of 24-bit integers in ipio2[].
+ *
+ * Input parameters:
+ *      x[]     The input value (must be positive) is broken into nx
+ *              pieces of 24-bit integers in double precision format.
+ *              x[i] will be the i-th 24 bit of x. The scaled exponent
+ *              of x[0] is given in input parameter e0 (i.e., x[0]*2^e0
+ *              match x's up to 24 bits.
+ *
+ *              Example of breaking a double positive z into x[0]+x[1]+x[2]:
+ *                      e0 = ilogb(z)-23
+ *                      z  = scalbn(z,-e0)
+ *              for i = 0,1,2
+ *                      x[i] = floor(z)
+ *                      z    = (z-x[i])*2**24
+ *
+ *
+ *      y[]     ouput result in an array of double precision numbers.
+ *              The dimension of y[] is:
+ *                      24-bit  precision       1
+ *                      53-bit  precision       2
+ *                      64-bit  precision       2
+ *                      113-bit precision       3
+ *              The actual value is the sum of them. Thus for 113-bit
+ *              precison, one may have to do something like:
+ *
+ *              long double t,w,r_head, r_tail;
+ *              t = (long double)y[2] + (long double)y[1];
+ *              w = (long double)y[0];
+ *              r_head = t+w;
+ *              r_tail = w - (r_head - t);
+ *
+ *      e0      The exponent of x[0]. Must be <= 16360 or you need to
+ *              expand the ipio2 table.
+ *
+ *      nx      dimension of x[]
+ *
+ *      prec    an integer indicating the precision:
+ *                      0       24  bits (single)
+ *                      1       53  bits (double)
+ *                      2       64  bits (extended)
+ *                      3       113 bits (quad)
+ *
+ * External function:
+ *      double scalbn(), floor();
+ *
+ *
+ * Here is the description of some local variables:
+ *
+ *      jk      jk+1 is the initial number of terms of ipio2[] needed
+ *              in the computation. The minimum and recommended value
+ *              for jk is 3,4,4,6 for single, double, extended, and quad.
+ *              jk+1 must be 2 larger than you might expect so that our
+ *              recomputation test works. (Up to 24 bits in the integer
+ *              part (the 24 bits of it that we compute) and 23 bits in
+ *              the fraction part may be lost to cancelation before we
+ *              recompute.)
+ *
+ *      jz      local integer variable indicating the number of
+ *              terms of ipio2[] used.
+ *
+ *      jx      nx - 1
+ *
+ *      jv      index for pointing to the suitable ipio2[] for the
+ *              computation. In general, we want
+ *                      ( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
+ *              is an integer. Thus
+ *                      e0-3-24*jv >= 0 or (e0-3)/24 >= jv
+ *              Hence jv = max(0,(e0-3)/24).
+ *
+ *      jp      jp+1 is the number of terms in PIo2[] needed, jp = jk.
+ *
+ *      q[]     double array with integral value, representing the
+ *              24-bits chunk of the product of x and 2/pi.
+ *
+ *      q0      the corresponding exponent of q[0]. Note that the
+ *              exponent for q[i] would be q0-24*i.
+ *
+ *      PIo2[]  double precision array, obtained by cutting pi/2
+ *              into 24 bits chunks.
+ *
+ *      f[]     ipio2[] in floating point
+ *
+ *      iq[]    integer array by breaking up q[] in 24-bits chunk.
+ *
+ *      fq[]    final product of x*(2/pi) in fq[0],..,fq[jk]
+ *
+ *      ih      integer. If >0 it indicates q[] is >= 0.5, hence
+ *              it also indicates the *sign* of the result.

+/* expm1(x)
+ * Returns exp(x)-1, the exponential of x minus 1.
+ *
+ * Method
+ *   1. Argument reduction:
+ *      Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658
+ *
+ *      Here a correction term c will be computed to compensate
+ *      the error in r when rounded to a floating-point number.
+ *
+ *   2. Approximating expm1(r) by a special rational function on
+ *      the interval [0,0.34658]:
+ *      Since
+ *          r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
+ *      we define R1(r*r) by
+ *          r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
+ *      That is,
+ *          R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
+ *                   = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
+ *                   = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
+ *      We use a special Remez algorithm on [0,0.347] to generate
+ *      a polynomial of degree 5 in r*r to approximate R1. The
+ *      maximum error of this polynomial approximation is bounded
+ *      by 2**-61. In other words,
+ *          R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
+ *      where   Q1  =  -1.6666666666666567384E-2,
+ *              Q2  =   3.9682539681370365873E-4,
+ *              Q3  =  -9.9206344733435987357E-6,
+ *              Q4  =   2.5051361420808517002E-7,
+ *              Q5  =  -6.2843505682382617102E-9;
+ *              z   =  r*r,
+ *      with error bounded by
+ *          |                  5           |     -61
+ *          | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2
+ *          |                              |
+ *
+ *      expm1(r) = exp(r)-1 is then computed by the following
+ *      specific way which minimize the accumulation rounding error:
+ *                             2     3
+ *                            r     r    [ 3 - (R1 + R1*r/2)  ]
+ *            expm1(r) = r + --- + --- * [--------------------]
+ *                            2     2    [ 6 - r*(3 - R1*r/2) ]
+ *
+ *      To compensate the error in the argument reduction, we use
+ *              expm1(r+c) = expm1(r) + c + expm1(r)*c
+ *                         ~ expm1(r) + c + r*c
+ *      Thus c+r*c will be added in as the correction terms for
+ *      expm1(r+c). Now rearrange the term to avoid optimization
+ *      screw up:
+ *                      (      2                                    2 )
+ *                      ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
+ *       expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
+ *                      ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
+ *                      (                                             )
+ *
+ *                 = r - E
+ *   3. Scale back to obtain expm1(x):
+ *      From step 1, we have
+ *         expm1(x) = either 2^k*[expm1(r)+1] - 1
+ *                  = or     2^k*[expm1(r) + (1-2^-k)]
+ *   4. Implementation notes:
+ *      (A). To save one multiplication, we scale the coefficient Qi
+ *           to Qi*2^i, and replace z by (x^2)/2.
+ *      (B). To achieve maximum accuracy, we compute expm1(x) by
+ *        (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
+ *        (ii)  if k=0, return r-E
+ *        (iii) if k=-1, return 0.5*(r-E)-0.5
+ *        (iv)  if k=1 if r < -0.25, return 2*((r+0.5)- E)
+ *                     else          return  1.0+2.0*(r-E);
+ *        (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
+ *        (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
+ *        (vii) return 2^k(1-((E+2^-k)-r))
+ *
+ * Special cases:
+ *      expm1(INF) is INF, expm1(NaN) is NaN;
+ *      expm1(-INF) is -1, and
+ *      for finite argument, only expm1(0)=0 is exact.
+ *
+ * Accuracy:
+ *      according to an error analysis, the error is always less than
+ *      1 ulp (unit in the last place).
+ *
+ * Misc. info.
+ *      For IEEE double
+ *          if x >  7.09782712893383973096e+02 then expm1(x) overflow
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.

+/* double log1p(double x)
+ * Return the natural logarithm of 1+x.
+ *
+ * Method :
+ *   1. Argument Reduction: find k and f such that
+ *                      1+x = 2^k * (1+f),
+ *         where  sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ *      Note. If k=0, then f=x is exact. However, if k!=0, then f
+ *      may not be representable exactly. In that case, a correction
+ *      term is need. Let u=1+x rounded. Let c = (1+x)-u, then
+ *      log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
+ *      and add back the correction term c/u.
+ *      (Note: when x > 2**53, one can simply return log(x))
+ *
+ *   2. Approximation of log(1+f): See log.c
+ *
+ *   3. Finally, log1p(x) = k*ln2 + log(1+f) + c/u. See log.c
+ *
+ * Special cases:
+ *      log1p(x) is NaN with signal if x < -1 (including -INF) ;
+ *      log1p(+INF) is +INF; log1p(-1) is -INF with signal;
+ *      log1p(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ *      according to an error analysis, the error is always less than
+ *      1 ulp (unit in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.
+ *
+ * Note: Assuming log() return accurate answer, the following
+ *       algorithm can be used to compute log1p(x) to within a few ULP:
+ *
+ *              u = 1+x;
+ *              if(u==1.0) return x ; else
+ *                         return log(u)*(x/(u-1.0));
+ *
+ *       See HP-15C Advanced Functions Handbook, p.193.

+Note: 1) ensures that k + logc can be computed without rounding error, 2)
+ensures that z/c - 1 can be computed as (z - chi - clo)*invc with close to a

+	     u = 3 - s*r
+	     r = r*u/2
+	     s = s*u/2

+	   the advantage of goldschmidt is that the mul for s and r
+	   are independent (computed in parallel), however it is not
+	   "self synchronizing": it only uses the input m in the
+	   first iteration so rounding errors accumulate. at the end
+	   or when switching to larger precision arithmetics rounding
+	   errors dominate so the first iteration should be used.

+# The directory containing all PKGBUILDs for BOX64
+## FAQ
+### 1. How to use it?
+Just download the `PKGBUILD-<your-platform>` (no need to download the whole repository), go to directory where you downloaded and type:
+```sh
+mv ./PKGBUILD-<your-platform> ./PKGBUILD
+# use the below line if you need a DEBUG build
+# sed -i 's/RelWithDebInfo/Debug/g' ./PKGBUILD
+cd ..
+makepkg -si
+```
+This will copy the PKGBUILD for your platform (where you type your platform name instead of `<your-platform>`), build it and install the PKGBUILD on 64-bit Archlinux ARM.
+
+In the future, I might try to do an unified PKGBUILD for all platforms that will recognize your platform automatically.
+
+### 2. What platforms are currently supported.
+All specified in [COMPILE.md](../docs/COMPILE.md) except for LARCH64, PPC64LE and SW64.
+
+### 3. Any advantages with this solution?
+This might give you some advantages like:
+- automatic updates (with some AUR frontends like [`pamac-aur`](https://aur.archlinux.org/packages/pamac-aur/) or [`yay`](https://aur.archlinux.org/packages/yay));
+- easily uninstall with `pacman -R` when no needed (no need other scripts nor Makefile to do this);
+- your `box64` installation is recognized as a package (where it wasn't when installing with `make install`).
+
+
+### Note: You can use [makedeb](https://github.com/makedeb/makedeb) (or) [pkgbuild2spec](https://github.com/prozum/pkgbuild2spec) to compile box64 to .deb or .rpm installer files.
