This requirement to always take a second sub-command makes it different from `swift build` and `swift test` too. Are there any commands to `swift` current that require a sub-command to work?

While I'm thinking about this...

Are there any commands to `swift` that are not package manager commands? If not, then another option is to move all the package manager operations to top level commands of `swift`. e.g. `swift init`, `swift generate-xcodeproj` etc. This solves the discoverability and tab completion between `swift` and `swiftpm` problem completely, and also makes for a sane api of:

$ swift init
$ swift add https://github.com/apple/example-package-playingcard.git
$ swift build
$ swift test


As an aside, anone of the subcommands to `swift` are discoverable because `swift -h` displays "OVERVIEW: Swift compiler" and doesn't imply that it does anything different to `swiftc` which also says "OVERVIEW: Swift compiler" when you do `swift -h`, but has a different set of options :)
