Craft Parts

Craft-parts provides a mechanism to obtain data from different sources, process it in various ways, and prepare a filesystem subtree suitable for deployment. The components used in its project specification are called parts, which can be independently downloaded, built and installed, and also depend on each other in order to assemble the subtree containing the final artifacts.
