## Historique du projet et usages

addlicense is a Google-maintained Go command that recursively scans source trees and adds or checks copyright license headers. It is deliberately simple: run it over patterns, choose a supported license template or file, and optionally fail CI with -check.

### Historique du projet

The official GitHub repository was created in June 2016. Its README describes a Go program that modifies source files in place, avoids duplicating headers that already exist, and supports Apache, BSD, MIT, and MPL-style headers plus custom license files.

The project is hosted under the google organization but explicitly says it is not an official Google product. The official tag list shows stable v1.x tags, and the README now documents Go installation, a GitHub Container Registry image, and pre-commit integration.

### Historique d'adoption

addlicense fits the common open-source maintenance workflow where license headers are enforced in presubmit, CI, or pre-commit rather than by hand. The supplied package-manager metadata shows Homebrew and Nix packaging, while the README documents go install, Docker, and an official pre-commit hook.

### Modes d'utilisation

Typical use is addlicense . or addlicense with multiple file and directory patterns. Important package-maintainer flags include -check for verification-only runs, -ignore for vendored or generated files, -l for the license family, -f for custom text, -s for SPDX identifiers, and -c/-y for copyright holder and year.

### Pourquoi les passionnés de paquets s'y intéressent

For package and release engineers, addlicense is a boring tool in the best sense: it makes source-header policy reproducible and automatable. It is useful in repos where license conformance needs to be enforced before vendoring, releasing, or importing code into downstream packaging.

### Chronologie
