XeTeX

XeTeX Publisher's Description:
XeTeX is a TeX-based typesetting tool for Mac OS X, making use of Unicode together with AAT and OpenType font technologies.
XeTeX is designed to provide a tool particularly suited to formatting long, structured documents, and supporting multilingual typesetting and complex non-Roman scripts. It merges the TeX typesetting system developed by Donald E. Knuth with the Unicode rendering capabilities of ATSUI and AAT fonts on Mac OS X, plus support for OpenType font layout features. This means that it can be used to typeset complex scripts just as readily as English, by simply specifying an appropriate AAT or OpenType font from among those installed in OS X; no complex font installation or configuration is needed.

What's new in this version:
Updated to integrate better with newer TeX installations (TeXLive 2004 and later); improved support for legacy Type 1 fonts used with TeX; new features to support non-Unicode input files; line-breaking support for East Asian languages without word spacing; numerous minor enhancements and bug-fixes.
