The full licence text is preserved at src/vendor/gumbo/COPYING. Upstream
ships no NOTICE file. The Apache License, Version 2.0 and the package's own
MIT license are separate and apply to their respective files; the MIT
license does not cover the vendored Gumbo sources.
The files are upstream's, with a short series of local patches applied:
error.c, error.h, gumbo.h and parser.c are modified, and each says so under
its licence header. The patches are listed in src/vendor/PROVENANCE.
The copyright notices above are the only ones found in the vendored file
headers. Later changes by the fork's maintainers carry no separate notice.
