WordGenerator generates hypothetical words from specifications of their syllable structure. The user specifies the maximum length of the words in syllables, the abstract structure of syllables in the language (in terms of such units as consonants and vowels or onsets and rhymes), and the actual sounds that comprise each abstract class (e.g. the list of vowels in the language); WordGenerator then generates the words that conform to this specification. Such lists are useful to field linguists exploring the vocabulary of a language, and to designers of artificial languages.

Git is a "directory content manager" that was designed to handle massive projects such as the Linux kernel with speed and efficiency. It falls in the category of distributed source code management tools and is similar to GNU Arch, Monotone, and BitKeeper. Every Git working directory is a fully-fledged repository with full revision tracking capabilities and is not dependent on network access to a central server.
