that old daemon wakes from the sleep of the power cut, and cries: > The following information was provided by the package's contributor. > > Name of contribution: expl3 > Author's name: The LaTeX Project > Location on CTAN: /macros/latex/contrib/expl3/ > Summary description: Low-level LaTeX3 programming conventions > License type: lppl > > Announcement text given by the package's contributor: > ---------------------------------------------------------------------- > ---------------------------------------------------------------- > ---------------------------------------------------------------- > The expl3 bundle: Low-level LaTeX3 programming conventions > ---------------------------------------------------------------- > > The files of the expl3 bundle provide a low-level API for TeX > programmers with special syntax conventions, completely > separating it from document level syntax.
