The VLT-Flames Tarantula Survey: an overview of the VFTS results so far
  The VLT-FLAMES Tarantula Survey (VFTS) has acquired multi-epoch spectroscopy
of over 800 O, B and Wolf-Rayet stars in the 30 Doradus region with the aim to
investigate a number of important questions related to the evolution of massive
stars and of cluster dynamics. In this paper, I first provide an overview of
the scientific results obtained by the VFTS consortium so far. I then review
the constraints obtained on the multiplicity properties of massive stars in 30
Dor and compare them to our recent results from a Milky Way sample.
