version 0.1.1
The jsonfile Python module can be used to sync a JSON file on a disk with the corresponding Python object instance.
Can be used to autosave JSON compatible Python data.
By default the content of the JSON file is human readable and version control friendly.
WARNING! This results an extremely slow backend!
