For the record, here's what I wrote first (before greeting a few redlings from Xcode) :

```
/* Build back an URL to the temporary fixture folder */

NSURL *masterRepoURL = [NSURL fileURLWithPath:[self pathForFixtureRepositoryNamed:@"testrepo.git"]];
NSURL *fixturesURL = [NSURL fileURLWithPath:self.repositoryFixturesPath];
```
