Changes

Please note from the start that we recommend installing a complete ConTeXt installation for each project in a production environment. The installation tree is portable (see Moving the Installation Around, below) and can be located under the project's own directory. The advantage is to allow each project to use an instance of ConTeXt that is adapted to its coding and that only gets updated purposely. Since the ConTeXt Standalone is "bleading bleeding edge" and subject to developementdevelopment, certain details in commands, syntax or rendering may evolve slightly. Having a vintage ConTeXt tree for each production project insures that one can come back years later and produce identical results.
