xmlroff (http://xmlroff.org) is an XSL Formatter written in C that produces PDF and PostScript. xmlroff 0.3.0 builds solely on open source software since it no longer supports a PDFlib backend. It also plays well with GNOME desktops since it uses Pango and the new PangoXSL library (from the PangoPDF project) instead of the previous PangoPDF library.
