Additional Permission: Packaging of Official Binaries

In addition to the licenses granted under the PolyForm Internal Use
License 1.0.0 below, which this permission does not otherwise modify,
the licensor grants you permission to redistribute the official binary
releases of the software, free of charge, as packages in software
repositories, package managers and app stores (for example Flathub,
the Snap Store, the AUR, Linux distribution repositories, Homebrew,
Scoop and winget), on these conditions:

1. The files are the official release files published at
   https://github.com/amru195704/UwDiff/releases, and the program files
   are not modified. Unpacking them, placing them in the package's
   layout, and adding desktop entries, icons, metadata or launcher
   scripts are allowed.
2. The SHA-256 hash of each file matches the SHA256SUMS file published
   with that release.
3. The package includes this LICENSE file or links to it, and states
   that the software is not open source software.
4. The package does not suggest that it is made or endorsed by the
   licensor, unless the licensor has said so.
5. No fee is charged for the software itself.

This permission does not cover the source code, modified or rebuilt
binaries, or bundling the software into another product or service.
Those still require a separate commercial license from the licensor.
Anyone who installs such a package receives the software under these
same terms.
