This is a bundle of extensions to TeX to provide bidirectional typesetting; it is expressed as a web change file.

Note that the TeX--XeT code has been incorporated into extensions, so that engines incorporating the code directly are rarely found nowadays. Indeed, Knuth himself no longer distributes TeX--XeT, so it is to be considered obsolete.

The authors are Peter Breitenlohner, Donald E. Knuth and Pierre A. MacKay. The package is Copyright © 1992 Dante e.V..
