 Bashbrew will fetch code out of the Git repository (`GitRepo`) at the commit specified (`GitCommit`). If the commit referenced is not available by fetching `master` of the associated `GitRepo`, it becomes necessary to supply a value for `GitFetch` in order to tell Bashbrew what ref to fetch in order to get the commit necessary.
