Fastjar is a version of Sun's `jar' utility, written entirely in C, and therefore quite a bit faster. Fastjar can be up to 100x faster than the stock `jar' program running without a JIT. Currently, the author is working on adding all the features present in the Sun utility. At the moment, implemented features are: * Archive creation * Verbose/quiet output * stdout vs. file output * Manifest file support * Deflation or storage * Changing to a dir and adding files (-C) * Archive content listing (-t) * Archive extraction (-x)
