 - [ ] **carthageExecutablePath**: **String** - The path to the carthage executable. Defaults to `carthage`. You can specify when you use custom built or locally installed Carthage using [Mint](https://github.com/yonaskolb/Mint), for example.
 - [ ] **createIntermediateGroups**: **Bool** - If this is specified and set to `true`, then intermediate groups will be created for every path component between the folder containing the source and next existing group it finds or the base path.

The target name will be stripped of all characters that aren't alphanumerics, hyphens, or periods. Underscores will be replace with hyphens.
