Argh! is an esoteric programming language in the spirit of Befunge, Brainfuck, and friends. It is a nice and simple language with two dimensional code-flow, a combined code/data array, an infinite stack, regular characters for all instructions, no strange braces or symbols, no unnecessary arithmetic operators (add and sub are all you need), and countless other features it doesn't have. The distribution includes interpreters for Argh! and Aargh! (an extended Argh! that is most likely Turing complete), the official specification, editing modes for emacs and vim, and lots of examples.
chsuf changes the suffix of file and/or directory names. It also can be used to add or remove a suffix to/from a list of files. chsuf can be useful for changing DOS-style three character extensions to more readable variations (e.g. from .htm to .html), or for adding an extension to filenames for use on platforms which depend on filename extensions.
