appimagetool

Purpose: appimagetool generates an AppImage from an existing AppDir.
Intended users: The project describes AppImage packaging as a way for application authors to distribute desktop Linux applications across common Linux distributions.
Higher-level tools: The README says many community-provided higher-level tools for deploying applications in AppImage format use appimagetool internally, and recommends using them instead of calling appimagetool directly in most cases.
Build options: The command-line options include listing AppImage files, setting or guessing update information, choosing Squashfs compression, and excluding files.
Signing: The tool supports GPG signing with options for a signing key and extra signing arguments.
Update metadata: When update information is embedded and zsyncmake is installed, the tool can generate a zsync file.
Architectures: The build instructions list x86_64, i686, aarch64, and armhf targets.
Runtime requirement: The current version downloads the latest AppImage runtime, or can use a locally supplied runtime file when the build system lacks internet access or the user prefers a local runtime.
Integrations: The README documents guessing update information from environment variables used by GitHub Actions and GitLab CI.
License: The repository’s original source code is licensed under the MIT License, subject to exceptions for files or directories with different terms and for dependencies.
Support: The AppImage project site points users to its Discourse forum and mailing list for questions, and to the #AppImage channel on irc.libera.chat for live chat.
Notable limitation: An AppDir is expected as input, and ARCH must be set when the tool cannot determine the architecture of the binaries, such as when the AppDir contains multiple architectures or only shell scripts.
