text-based authoring tool for HTML
Aephea is an HTML authoring framework. It enforces HTML well-formedness with a simpler and stricter syntax, provides useful extensions and abstractions as well as facilities for adding new ones, all in a single unified approach that stays close to HTML itself. Some of Aephea's characteristics are a TeX-like syntax, dictionary stacks, iteration and a focus on styling via CSS. . PUD (Portable Unix Documentation) is shipped with Aephea. It provides mini-languages for authoring Unix manual pages and FAQ documents with output both in HTML and troff. . Both Aephea and PUD are written in zoem, a high-level macro/programming language with character filtering capabilities. . If you'd like to generate manpages, but don't like troff syntax, and find Perl's POD too limited, Aephea's PUD is likely useful for you. If you like your documents to be available in both PDF and HTML, but find DocBook XML too heavyweight (and aren't really happy with Docbook XML's baroque default tagnames), you'll like PUD.
