java_syn.pl is a syntax highlighter for Java that converts a package of multiple .java files to multiple .html files. Class names are converted to links, so the reader can click on a class name to immediately see its source code. Default highlighting colors are the same as in Textpad.
XML-Lit is a simple program to perform very basic literate programming with any XML-based markup language. It uses James Clark's Expat XML parser to weave (convert to a form suitable for processing) and tangle (extract the source code from) your XML documents. It has only been tested with DocBook at the moment, but there is no reason why it should not work with any arbitrary XML markup.
EFEU is suitable for handling data cubes, which are especially useful for building data warehouses. It consists of a building system including mkmf (a xmkmf like Makefile generator), esh (a powerful C/C++ interpreter), efeudoc (a document generator with different output formats (LaTeX, HTML, roff, etc.)). EFEU has a huge set of C library core features, including robust memory allocation tools, functions to concatenate and copy strings with memory allocation, buffers for dynamically-growing strings and fields, data structures with reference counters and garbage collection, and file tools that allow you to specify pipes wherever a filename is expected and support automatic implementation of (de)compression filters (gzip) depending on filename extensions. It also includes a high-level interface to files, strings, and anything else you can read from or write to.
Jamit (Java Access Modifiers Inference Tool) allows you to infer tighter access modifiers for Java code. Analyzing bytecode, it can find out if fields or methods may be declared private, default, protected, or final. Engineering software with Jamit can thus help increase hiding and keep interfaces as small as possible. The most useful application for Jamit is dead code elimination. Jamit can be used to find out which methods and classes are unreachable and automatically eliminate the corresponding code, saving space for binary distributions.
The sourcecode XML metadata extraction tools are intended to be used for extracting and transforming XML-like markup embedded in source code comments into syntactically correct external entities or well-formed XML files. This can be used for JavaDoc-like code annotation, providing structured comments, or even embedding metadata used by the build process or configuration management tools.
