Aleph and LuaTeX
Although the project seemed very promising from the beginning, the development has been slow and the functionality rather unstable. A separate project was started with the goal of stabilizing the code and extending it with e-TeX functionality, known as Aleph, and led by Giuseppe Bilotta.
The LaTeX for Aleph is known as Lamed.
Aleph alone is not being developed any more, but most of its functionality has been integrated into LuaTeX, a new project initially funded by Colorado State University (through the Oriental TeX Project by Idris Samawi Hamid) and NTG. LuaTeX started in 2006 and released the first beta version in Summer 2007. It will be a successor of both Aleph and pdfTeX, using Lua as an integrated lightweight programming language. It is developed primarily by Taco Hoekwater.
