Flagpoll is a tool for developers to use meta-data files for storing information on what is needed to compile their software. Think of it as the rpm of software development. It provides developers with total control over which packages, versions, architectures, et cetera that they want to use meta-data from. Instead of specifying other packages' cflags and ldflag manually, you can call `flagpoll mylib --cflags --ldflags` and it will retrieve the flags for its package as well as its dependencies.
Free Java is a development environment designed to help beginners write Java programs. Its editor includes syntax highlighting and an undo/redo function.

GBAconv is a set of tools aimed at GameBoy Advance developers, allowing them to convert WAV sounds and PCX images into C arrays to be included in GBA programs. It is composed of two programs: pcx2gba (exports a PCX 8-bpp image to 16-bit values C arrays: palette and image data (2 pixels per value)) and wav2gba (exports a WAV 8-bit mono sound to an 8-bit signed values array).
The GNU Autoconf Archive is a collection of more than 450 macros for GNU Autoconf. They can be re-used without imposing any restrictions on the licensing of the generated configure script. In particular, it is possible to use them in configure scripts that are meant for non-free software.
GNU Make examines the timestamps on a set of interdependent files, and, if necessary, issues commands to bring them up-to-date. The user creates a makefile describing the files, their relationships, and the commands to run. Most often make is used to rebuild libraries and programs when their sources are changed, but it can be used for any situation where one set of files needs to be generated from another set.
