• Retrieve any revision, using any criteria, anytime. Each revision is marked with a unique revision number, revision date, author name, optional symbolic name, and descriptive comment.

• Easily see the changes made between any two revisions. You can study the evolution of a file throughout its lifetime.

• Never lose any work because you can always backtrack. This is critical when there is a deadline and the last revision is preferable.

• Work with binary files. You can maintain revisions of binary files such as MS-Word documents, pictures, drawings, etc.

• Work with projects. You can apply RCS commands to the whole project, assign project milestones and apply related operations.

• Work with standard Windows applications. CS-RCS is seamlessly integrated with Microsoft Word and many Windows development tools.

• Save disk space. Since only the differences between revisions are saved, the archive file size is kept to the minimum size.

• Work in parallel. CS-RCS supports unlimited concurrent lines of development (branches) and performs automatic merging when possible (Professional edition only).

A single user licence is free.

Subversion is meant to be a better CVS, so it has most of CVS's features. Generally, Subversion's interface to a particular feature is similar to CVS's, except where there's a compelling reason to do otherwise.
