While a first demonstrator NTS did +appear, it wasn’t practically useful, and the project seems no longer +active. +<p>In parallel with its work on NTS itself, the project developed +a set of extensions that can be used with a (“true”) TeX system. +Such a modified system is known as an e-TeX system, and the concept +has proved widely successful. Indeed, current TeX distributions +are delivered with most formats built with an e-TeX system (for +those who don’t want them, e-TeX’s extensions can be disabled, leaving +a functionally standard TeX system). +<p>The extensions range from the simple (increasing the number of +available registers from 256 to 65536) through to extremely subtle +programming support. +<p><a href="FAQ-context.html">ConTeXt</a> has required e-TeX for its operation +for some time. +<p>Some LaTeX packages already specify the use of e-TeX. Some such +packages may not work at all on a non-e-TeX system; others will +work, but not as well as on an e-TeX system. The +<a href="FAQ-LaTeX3.html">LaTeX team</a> has announced that future LaTeX +packages (specifically those from the team, as opposed to those +individually contributed) may require e-TeX for optimum performance. +<p><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=etex">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=etex</a> +</body> |
