The tools are in a single package form, and the package installs them into /usr/bin. Then, just type from anywhere in the terminal:
% unrar e archive.rarAnd of course, it still works if you have multiple archives attached (.r00, .r01, r02...).
% unace e archive.ace
For binchunker, it will convert .bin/cue or .raw/.cue (made by any PC CD burning software) in .iso or .cdr (that can be burned with Toast).
