If you store the relative path, how can you resolve it in download time and still maintain the behavior described in option number 2, described in previous comment?

For example, in the following situation:

```console
$ ruby-tapas-downloader configure -e foo@bar.com -p 123 -l .
$ cd ..
$ ruby-tapas-downloader download
```

I don't mind calling `#expand_path` many times, because: `x.expand_path.expand_path == x.expand_path` for all `xs`.
