# Source and licence notice

ical.js2.2.1, pinned revision e6b2e61930d819ff72a7e5b399d52c8b92131106.
Original source at https://github.com/kewisch/ical.js/ . vendor/ical/ is a
copy of lib/ical/ at that revision, except time.js weekNumber is replaced by a throwing stub. This inventory does not use that method. Every original per-file licence
and copyright notice is retained. Covered source is available as served modules
and in source.zip under MPL-2.0, whose full text is vendor/LICENSE.

The Chawso core/worker/UI files are separate new MIT files, terms in LICENSE.
This larger work does not restrict recipients' rights in MPL-covered source.
No runtime dependencies, webfonts, framework or external services added.

Original time.js credits its weekNumber algorithm to Julian Bucknall under MIT,
with the original article link retained in that file. The upstream credit remains noted, but the algorithm itself is not
distributed or called in this inventory build. time.js now has a throwing stub.

Do not add recurrence expansion to this modified library: upstream recurrence
iterators call weekNumber. The inventory boundary is intentional.
