## l3kernel – LaTeX3 programming conventions

The l3kernel bundle provides an implementation of the 3 programmers’ interface, as a set of packages that run under . The interface provides the foundation on which the 3 kernel and other future code are built: it is an API for programmers. The packages are set up so that the 3 conventions can be used with regular packages.
