added alias to path file

eidng8 · web-flow · commit df4847c16ac4 · 2016-07-29T16:47:20.000+08:00
The `-pathFile` now accepts a '&gt;' separated plain text file, which
specifies the exported path and its alias.

e.g.

```
/some/path &gt; /alias
/other/path &gt; /another/alias
```

P.S. not sure if the code style is correct, the other branch uses space, but this branch uses tab.
