Synopsis

Usage l3build <target> [<options>] [<names>]

Description

The "l3build" module is designed to support the development of high-quality LaTeX code by providing:

* A unit testing system

* Automated typesetting of code sources

* A reliable packaging system for CTAN releases

The bundle consists of a Lua script to run the tasks and a ".tex" file which provides the testing environment. These were originally developed for supporting LaTeX development but are designed such that they can be readily used by others. Full documentation is provided.
