The LaTeX3 project team is a small group of volunteers whose aim is to produce a major new document processing system based on the principles pioneered by Leslie Lamport in the current LaTeX. It will remain freely available and it will be fully documented at all levels.
The LaTeX3 team has already delivered its first product, LaTeX2e, a macro package based on Lamport's original code, but modified to be more readily supportable than was Lamport's.
