A fine-grained and flexible version control for software artifacts

Version control is an activity very important for high-quality software production. The structure used by version control systems is the same used by file systems, but in general the abstraction level made by software developers considers the file contents and its internal structure, including details as classes, methods, control blocks and others. Fine-grained version control tools can provide a more detailed version control. However traditional tools and models provide very low flexibility and present high cost and impact of deployment in software development environments. In this paper, there are presented a model and a tool which aim at providing support to fine-grained version control activities.
