See inside opendirdl.py for usage instructions.
- 2016 10 01
- **[bugfix]** Fixed the download function so it actually passes `headers` into downloady.
- **[change]** `url_split` key 'root' has been renamed to 'domain'.
- **[cleanup]** Removed import for Ratelimiter since downloady handles all of that now.
- **[cleanup]** Improved some variable names, including `walkurl -> root_url`.
- 2016 08 16
- **[cleanup]** Now that Downloady uses temp files for incomplete downloads, that logic can be removed from opendirdl.
