      With its ability to "translate the history" from one VCS kind to another,
      this tool makes it easier to keep the upstream changes merged in
      a own branch of a product.

      Tailor is able to fetch the history from Arch, Bazaar, CVS, Darcs, Monotone,
      Perforce or Subversion and rewrite it over Aegis, Bazaar, CVS, Darcs, Git,
      Mercurial, Monotone and Subversion.
