Anastasia is designed for handling large and highly-complex XML documents, where extremely precise control is required over the presentation of these. It can create output in any format, and it is optimized for HTML output direct to web browsers. Anastasia permits you to publish documents in identical form both on CD-ROM (Macintosh and Windows) and on the internet, from identical scripts. It includes full support for all valid XML and SGML documents, and a fully XML-aware search engine. Anastasia’s ease of use makes it suitable for small publishers with comparatively fewer computer resources, while its power fits it for large publishing enterprises. Anastasia is open source.
