Markdown Doclet is a replacement for the standard Sun Java Doclet that allows developers to use Markdown syntax in their Javadoc comments rather than embedding unreadable HTML. The advantage of Markdown is that the syntax allows for HTML to be passed through, allowing the Markdown doclet to be applied to any existing codebase which may contain HTML Javadoc comments. It also includes a patched version of UMLGraph which calls the Markdown Doclet instead of the Sun standard doclet. The doclet also writes a more modern stylesheet for more attractive Javadocs.
Saros is a Eclipse plugin for collaborative text editing that in particular targets distributed pair programming (also called remote pair programming), but can support arbitrarily many participants at once. All members of a session have an identical copy of an Eclipse project and Saros keeps these copies in sync as editing progresses.
