Doxygen is a JavaDoc like documentation system for C++, C, Java and IDL.
Direct C++ to C# translator, translates one of the languages to another without compiling. Has academic aim only!!!
Check for unused #includes in C++ source
Unused #includes in C++ source lead to unwanted dependencies and slower compile and link timings. IncludeChecker finds most of these unused #includes using a simple heuristic: if you include a file, you need to use one or more symbols from it. If that's not the case, IncludeChecker will mark the #include as unused. IncludeChecker is very customizable to be able to run as an automated task where it will fail as soon as an unused #include is detected. Because of the simple heuristic it will not find all unused #includes, but it will find most of them.
REL (Research and Education Language) is a simple but very powerfull language with a compiler, an interpreter and a verifier.
