+ Use config/user.json to maintain the user information in a little different way comparing with m2w 1.0.
+ You can just keep your file structures locally as you like.
+ You can manage lots of websites at the same time via multiple legacy_*.json.
+ All you need to deal with is a single python script m2w.py instead of two (update.py and upload.py in m2w 1.0).
+ Stable and useful as m2w 1.0.
