This software uses language profiles which were created based on common text for each language. N-grams, a contiguous sequence of n items from a given sample of text, were then extracted from that text and stored in the profiles. When trying to figure out in what language a certain text is written, the program goes through the same process: It creates the same kind of n-grams of the input text. Then it compares the relative frequency of them, and finds the language that matches best. Currently 71 languages are supported.

Jakarta JSON Processing provides portable APIs to parse, generate, transform, and query JSON documents. This project contains Jakarta JSON Processing specification, API and TCK.

The intended audience of this library aren't day-to-day users, but package developers that wish to make use of newer functionality, not provided in older versions of Emacs, without breaking compatibility for users bound to specific Emacs releases.

PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorizations, algebraic number theory, elliptic curves...), but also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers etc., and a lot of transcendental functions. PARI is also available as a C library to allow for faster computations.

This package provides the Fast Process Manager interpreter that runs as a daemon and receives Fast/CGI requests. Note that MOST Apache users probably want the libapache2-mod-php8.2 package.

At the intersection of the Registry and Factory patterns lies the ClassRegistry.
