These are DSSSL stylesheets for the DocBook DTD by Norm Walsh. Use them in conjunction with a DSSSL processor (such as jade) to convert documents marked up as DocBook to other formats. For example (assume $DBPATH = /usr/pkg/share/sgml/docbook/dsssl/modular) jade -t sgml -d $DBPATH/html/docbook.dsl filename.sgml (DocBook -> HTML) jade -t rtf -d $DBPATH/print/docbook.dsl filename.sgml (DocBook -> RTF ) jade -t tex -d $DBPATH/print/docbook.dsl filename.sgml (DocBook -> TeX ) To further parse the output of the 'tex' transformation you will need the 'jadetex' macros. More documentation (in HTML format) is available in /usr/pkg/share/sgml/docbook/dsssl/modular/doc/
