Résumé
The component-based development paradigm brings various solutions for software reusability and better modular structure of applications. When applied in programming language context it changes the way dependencies and connections between software pieces are expressed. In this paper we present the Smalltalk implementation of "Exil", a component-based architecture description and programming language that makes it possible to use component related concepts (ports, interfaces, services,...) at design and if wished at programming time. This proposal enables Smalltalk users to develop their applications in the component-oriented style.
