Third-party notices
====================

drillion (this repository) is MIT licensed — see LICENSE.

84 of the 171 tasks under `tasks/` are adapted from Exercism's Python track and
carry Exercism's own Markdown verbatim in their `README.md`, by design (see
`README.md`). Each of those 84 files names its origin in a `source:`
frontmatter field and closes with an "Adapted from exercism/python — MIT"
line; run `grep -rl '^source:' tasks/*/README.md` to list them.

That content is drawn from:

- https://github.com/exercism/python
- https://github.com/exercism/problem-specifications

Both are MIT licensed:

This file reproduces that copyright and permission notice so it travels with
the repository, as MIT requires for a substantial portion of borrowed work.
It does not replace the per-file `source:` field and attribution footer on
each of the 84 tasks — those stay as the finer-grained record of exactly what
came from where.
