Automatically detect frameworks to upload/download from .version-file.

Enhancement Suggestion

Automatically detect frameworks to upload/download from .version-file.

Steps which explain the enhancement

1. Say you have file Carthage.resolved with the following contents github "facebook/facebook-ios-sdk" "sdk-version-4.21.0"
2. Dependency facebook-ios-sdk produces 3 frameworks during build process: FBSDKLoginKit.framework, FBSDKShareKit.framework, FBSDKCoreKit.framework.
3. Carthage generates .facebook-ios-sdk.version file with the following contents:

{
  "commitish" : "sdk-version-4.21.0",
  "iOS" : [
    {
      "hash" : "c22ab9aaf5b3049b6a5ce2387c714525a163d8b942f6d3d93ce533d37353d282",
      "name" : "FBSDKLoginKit"
    },
    {
      "hash" : "ca63365bfc88e599656c74a3e44b233b97b0dbb845b6ef1bf5df87db05baf023",
      "name" : "FBSDKShareKit"
    },
    {
      "hash" : "47de2a67234abb2245692056fc633c88bb4704bb68a66592fc991f538aa62665",
      "name" : "FBSDKCoreKit"
    }
  ]
}

Current and suggested behavior

Currently we have to setup configuration setting RepositoryMap to hint Rome which files to use during download/upload.

[RepositoryMap]
    facebook-ios-sdk = FBSDKCoreKit, FBSDKLoginKit, FBSDKShareKit

I am suggesting to update Rome in the way so that it will read framework names from .version-file. In this case we do not need to use RepositoryMap configuration setting in order to hint Rome which files to use during download/upload.

Why would the enhancement be useful to most users

Users will have better user experience and less configuration to setup. Reliability will be increased as well. For example: if in the future for some reason vendor will decide to change names and number of frameworks produced during Carthage build.

Rome version: 0.12.0.31 - Romam uno die non fuisse conditam. OS and version: macOS 10.12.5 (16F73)

Thank you!
