We provide pure::variants for managing multiple product variants using a software product line approach. There's a free evaluation version on the Software Acumen web site.

We also provide Axivion Bauhaus suite for identifying dead code, code clones (copy-pasted-edited fragments) and other analyses. Using Bauhaus can be a good step in cleaning up a code base and identifying reusable components or sub-component fragments when migrating to a software product line approach.
