The J2DGAMEFRAMEWORK provides the necessary classes to implement a simple 2D game in a window enviroment using Java Swing libraries. This framework also provides a Sprite Collision Manager and a simple GUI template. By using this framework, the developers only concern is how to implement classes, and not the 2D World, the collisions, etc. It uses the Observer Design Pattern. It has double-buffered rendering, simple use of collisions, and user-transparent multi-threading for collision classes. You can move sprites like a vector with speed and angle, and simply save and load your game.
bmake is a program designed to simplify the maintenance of other programs. Its input is a list of specifications as to the files upon which programs and other files depend. If no -f makefile makefile option is given, bmake will try to open 'makefile' and then 'Makefile' in order to find the specifications.
mk-configure is a lightweight replacement for GNU autotools written in and for bmake (a portable version of NetBSD make). The main goal is to have only one top-level tool instead of aclocal+automake+autoconf+autoheader. Other goals are clean design, simplicity, and "no code generation".
