Practical source is bundled from https://github.com/mcc-prac/stats.git
commit acb6e4f14edfed3b4f57ed78498c32186ca80f69.
All 14 Python sources preserve their code with UTF-8/LF normalization only.

The upstream snapshot has no license file. Public distribution requires
authorization from its source owner, recorded in the release evidence.
LICENSE states the package's local-use terms. These terms do not grant rights
beyond those authorized by the owners of the practical sources.

px-stat does not import or execute the practical code. NumPy and SciPy are
optional, separately installed dependencies for executing the inserted programs.
The extension is adapted from the project owner's px-idle implementation.
