   APP_NAME = 'appname'
   
   DEPLOY = {
       "host1": {  # same as ssh-config
           "task_prefix": "app-process",  # prefix of process name
           "home_path": '/path/to/appname/www',  # path of each versions
           "static_path": '/path/to/appname/statics',  # path of statics for each versions
