From b73cf0145a084ca6e74085edee72b03a95708925 Mon Sep 17 00:00:00 2001 From: Anders Olsson Date: Thu, 27 Aug 2026 17:35:42 +0200 Subject: [PATCH] chore: dual-license MIT OR Apache-2.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Rust ecosystem convention, and what kickscore, xy and saphyr already use — kickscore being the closest sibling to this crate. LICENSE-APACHE is the canonical 201-line Apache-2.0 text with the appendix left as the unfilled template, which is the form Rust crates ship. LICENSE-MIT carries the copyright line. Both are picked up by cargo automatically and appear in the packaged crate. This also unblocks the release workflow. `cargo publish` does not check the license field when the target is an alternative registry, but cargo-release does, and refuses outright: error: trueskill-tt is missing the following fields: license || license-file --no-verify does not bypass it. So `just release` was inert without this, whatever cargo publish alone would have accepted. README gains the conventional dual-license section and the contribution note that dedicates inbound contributions under the same terms.
