SciWriter 1.8 is an XML-based scientific editor that completely integrates mathematics and text in the same environment. The native document format is a subset of XHTML 1.1 and MathML 2.0 presentation markup. A SciWriter document can be exported to LaTeX and published as a PDF, PostScript, or DVI file. Documents also can be published on the Web as XHTML and MathML or as HTML with equations as images.
