//
// We do this by defining a file called "swiftmodule" that contains JUST the
// name of the Swift module at the root of your VDL packages. For example,
// if you have the VDL files for your Xcode project/target called UberForCats
// at /Users/aaron/uberforcats/vdl, then create
// /Users/aaron/uberforcats/vdl/com.uberforcats/swiftmodule and have it just contain
// "UberForCats". We then will treat any VDL files contained in that directory and
// any subdirectories as part of the UberForCats Swift module, ultimately letting
// the compiler and will automatically do the right thing if others import your package.
// If you don't do this then nobody will be able to import your VDL types in Swift,
// and you might end up with extra long class/pkg names (ComuberforcatsServicesProfit
// instead of ServicesProfit for $VDLROOT/com.uberforcats/services/profit).
//
// If you are creating multiple Swift modules for a given $VDLROOT then just place
// swiftmodule files at the logical boundaries. For eample, we do this for v.io/v23
