e-TeX – An extended version of TeX, from the NTS project
An extended version of TeX (which is capable of running as if it were TeX unmodified). E-TeX has been specified by the LaTeX team as the engine for the development of LaTeX2ε, in the immediate future; as a result, LaTeX programmers may (in all current TeX distributions) assume e-TeX functionality. The pdftex engine directly incorporates the e-TeX extensions.
The development source for e-TeX is the TeX Live source repository.
