JCPP is a complete, compliant, standalone, pure Java implementation of the C preprocessor. It is intended to be of use to people writing C-style compilers in Java using tools like sablecc, antlr, JLex, CUP, and so forth. It has been used to successfully preprocess much of the source code of the GNU C library.
SBuild is a Scala-based build system. It features platform independence, multi project support, automatic detection of needed actions, automatic up-to-date detection, a flexible scheme handler mechanism, Maven repository support, Ant task integration, automatic cross-project resolving of dependencies, high speed, a simple "syntax" that requires almost no Scala knowledge, behind-the-sceens compilation of build script to bytecode for fast execution time, and built-in scheme handlers for HTTP and Maven.
