SVNKit is an open-source, pure Java software library for working with the Subversion version control system. It is free to use on opensource projects but requires that you buy a commercial license to use to develop with proprietary software. It implements virtually all Subversion features and provides API to work with Subversion working copies, access and manipulate Subversion repositories.
