  10 //   [x] Dependencies - if System.dll -> include Mono.Security.* (not needed, automatic)
  11 //   [x] --list-targets should download from a different url
  12 //   [x] --fetch-target should unpack zip file
  13 //   [x] Update --cross to use not a runtime, but an SDK
  14 //   [x] Update --local-targets to show the downloaded SDKs
