CTAN update: expl3

the daemon is surely getting tired, after recent excessive exercise, but neverthe less he says: > The following information was provided by the package's contributor. > > Name of contribution: expl3 > Author's name: LaTeX project > Author's email: joseph.wright at morningstar2.co.uk > Location on CTAN: /macros/latex/contrib/expl3 > Summary description: Packages showing a proposed LaTeX3 programming convention > License type: lppl > > Announcement text given by the package's contributor: > ---------------------------------------------------------------- > The expl3 bundle: low-level LaTeX3 coding > ---------------------------------------------------------------- > > 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. Hence, the commands > provided are not intended for use at the document level nor for > use in describing design layouts in document class files. > > This API provides the foundation on which the LaTeX3 kernel > and other advanced extensions are built. Special care has been > taken so that they can be used within a LaTeX2e context as > regular packages. > > The TeX and eTeX primitives are all given a new name according > to these conventions.
