    A unit testing system for (La)TeX code (whether kernel code or contributed packages);
    A system for typesetting package documentation; and
    An automated process for creating CTAN releases.

The package is essentially independent of other material released by the LaTeX3 team, and may be updated on a different schedule.]],
