The Haskell

Haskell (programming language)

Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry. In Haskell, "a function is a first-class citizen" of the programming language. As a functional programming language, the...

 Cabal is the Common Architecture for Building Applications

Application software

Application software, also known as an application or an "app", is computer software designed to help the user to perform specific tasks. Examples include enterprise software, accounting software, office suites, graphics software and media players. Many application programs deal principally with...

 and Libraries; it aids in the packaging and distribution of software packages

Software package (installation)

In package management systems, which are commonly used with Linux-based operating systems, a package is a specific piece of software which the system can install and uninstall....

. It is contained in the Haskell Platform

Haskell Platform

The Haskell Platform is a collection of software-packages, tools and libraries, which is to create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: "Batteries included"...

.

Cabalizing

A process of making a library written in the Haskell programming language conformant to the requirements of the Cabal library infrastructure provided that the library was initially developed without taking those requirements into consideration, or prior to the introduction of Cabal to the Haskell community.

Use

Cabal packages provide a standard set of metadata

Metadata

The term metadata is an ambiguous term which is used for two fundamentally different concepts . Although the expression "data about data" is often used, it does not apply to both in the same way. Structural metadata, the design and specification of data structures, cannot be about data, because at...

 and build process; thus, it is possible to develop tools to upload Cabal packages to the CPAN

CPAN

CPAN, the Comprehensive Perl Archive Network, is an archive of nearly 100,000 modules of software written in Perl, as well as documentation for it. It has a presence on the World Wide Web at and is mirrored worldwide at more than 200 locations...
