JCite makes it possible to cite snippets of Java source code in your HTML documents (API documentation, for instance). The snippets are copied out of Java class source files, which should be part of the regular build. This guarantees that the cited snippets are always up-to-date. If you cite from unit tests, you even get the guarantee that they still work correctly. Finally, thanks to the excellent Java2Html library, the cited snippets get automatic syntax highlighting.
Rextile allows you to build XHTML documents and entire Web sites with ease. You write text using Textile (a format much more concise than XHTML), automate document parts with Ruby scripting, and generate the site offline (the server gets static XHTML). Rextile was inspired by Xilize. It uses RedCloth to convert Textile to XHTML, erb to run script blocks, and Hpricot for DOM manipulation.
DocPerl provides a Web-based interface to Perl's Plain Old Documentation (POD). It is a graphical, easy-to-use interface to POD, automatically listing all installed modules on the local host, and any other nominated directories containing Perl files. DocPerl can also display a summary of the APIs defined by files and the code of those files. It can search the POD documentation for module names and for functions defined in modules.
The DPML SDK is a management platform for Java-based component development, resource management, and deployment.
