semanticmerge is a language-dependent source code merge tool. It can make a huge number of merge scenarios really easy – particularly ones that can’t be managed by current text-based, language-agnostic merge tools. Since it is language-dependent, there will be different releases of Semantic Merge specific for different programming languages.
Semantic Merge is not limited to Plastic SCM and it can be configured to work with Git, Subversion, Perforce, ClearCase, Team Foundation Server, Mercurial, and many others.
