## License
* Windows builds are licensed `LGPL 2.1+` **by default**, can be disabled by appending `-DLGPL=OFF` to cmake.
* Non-windows builds and builds with `-DLGPL=OFF` are licensed MIT.

## Usage (Windows Only)
1. Download `chrome-pak.7z` from [releases](https://github.com/myfreeer/chrome-pak-customizer/releases) and extract it to any folder.
2. Drag the pak file and drop it to `unpack.bat`.
3. The pak file would be extracted to subfolder of the folder of the pak file,
with the same name of the pak file with an `_unpacked` suffix.
4. (Optional) modify extracted files.
5. Drag `pak_index.ini` to `pack.bat`.
6. Repacked pak file would be in the same folder of `pak_index.ini` with a name like `pak_index_packed.pak`.

There is also a [GIF Guide](https://github.com/myfreeer/chrome-pak-customizer/wiki/GIF-Guide-v2) on windows.

## Usage (Command line)

pak.exe -u pak_file destination_path

pak.exe -p pak_index_file destination_pak_file
