Nettle is a cryptographic library that is designed to fit easily in more or less any context: in crypto toolkits for object-oriented languages (C++, Python, Pike, etc.), in applications like LSH or GNUPG, or even in kernel space. In most contexts, you need more than the basic cryptographic algorithms; you also need some way to keep track of available algorithms and their properties and variants. You often have some algorithm selection process, often dictated by a protocol you want to implement. And as the requirements of applications differ in subtle and not so subtle ways, an API that fits one application well can be a pain to use in a different context, which is why there are so many different cryptographic libraries around. Nettle tries to avoid this problem by doing one thing, the low-level crypto stuff, and providing a simple but general interface to it. In particular, Nettle doesn't do algorithm selection. It doesn't do memory allocation. It doesn't do any I/O. The idea is that one can build several application- and context-specific interfaces on top of Nettle and share the code, testcases, benchmarks, documentation, etc.
NSokoban is a Sokoban game for PalmOS. Sokoban is an old but addictive game where the objective is to push boxes around and arrange them properly in the goal area. This implementation includes "one-box" undo, four sets of levels (the original 50 levels, some 45 extra levels, and two level sets by Yoshio Murase). NSokoban's source includes a program for converting text files which contain level data into a form that be loaded by the game. NSokoban consists of a portable sokoban game engine, a Palm GUI, and a primitive TTY interface (primarily for debugging). Full source code is available by anonymous CVS.
