James Clark's DSSSL Engine

 Jade is an implementation of the DSSSL style language.
 .
 The jade engine is a useful tool (in conjunction with a DSSSL style
 sheet) for translating SGML documents into other formats. Jade can
 currently generate SGML, RTF, and TeX. In conjunction with the "jadetex"
 TeX style, it can generate quite nice output.
