// Relative("/foo/bar") returns /home/fiam/example/foo/bar.
// Note that when running tests (from e.g. go test) or go run
// (e.g. go run myfile.go), this function will return the path relative
// to the current directory rather than the binary. This is done in
// order to allow functions which use relative paths to work under
// those circumstances, since go puts the binaries in a temporary
// directory when using go test or go run, but runs them from the
// current directory.
