1""" 

2An implementation of JSON Schema for Python 

3 

4The main functionality is provided by the validator classes for each of the 

5supported JSON Schema versions. 

6 

7Most commonly, `jsonschema.validators.validate` is the quickest way to simply 

8validate a given instance under a schema, and will create a validator 

9for you.
