1. // lib/releases.hl — RELEASES (ticket gitoria#12): /releases of a repo address.
2. // A release is a COMMIT on the repo's main branch whose subject starts `|||RL ` (patch +1), `|||RL|med `
3. // (minor +1, patch 0), `|||RL|mj ` (major +1, minor and patch 0) or `|||RL|<version> ` (set by hand,
4. // e.g. 1.1.1a). Nothing is stored: the main branch's history is read oldest → newest and the versions are
5. // counted up from 0.0.0 (so the first `|||RL ` is 0.0.1). A hand-set version that was released before
6. // is not a release. A release = its version, the text after the marker, the commit (link), author, date.
