l3kernel – LaTeX3 programming conventions
The l3kernel bundle provides an implementation of the LaTeX3 programmers’ interface, as a set of packages that run under LaTeX2ε. The interface provides the foundation on which the LaTeX3 kernel and other future code are built: it is an API for TeX programmers. The packages are set up so that the LaTeX3 conventions can be used with regular LaTeX2ε packages.
