What is Aragon Govern?

I am bit confused what Aragon Govern is.

  • There is Aragon Client to create a DAO and manage a DAO.
  • Aragon Voice is used in the Aragon Client for Aragon DAOs and for outside ERC20 communities
  • Aragon Court is used if users detect fraud/mistakes within a DAO or any other contract which is secured by the court and want to dispute them.

What is Aragon govern? Is Aragon govern all the above in one interface? Why not just call it Aragon?
