Requirements:
     - Python
     - pip install json pycurl urllib2 configargparse


Instructions:
    Execute command with option -d to retrieve config data from a host
    or use -f to read a configuration file saved using Tasmota Web-UI
    
    For further information read 'decode-config.md'

    For help execute command with argument -h (or -H for advanced help)

    Backup/Restore Sonoff-Tasmota configuration data. Args that start with '--'
    (eg. -f) can also be set in a config file (specified via -c). Config file
    syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax at
    https://goo.gl/R74nmi). If an arg is specified in more than one place, then
    commandline values override config file values which override defaults.
