"""
An implementation of JSON Schema for Python

The main functionality is provided by the validator classes for each of the
supported JSON Schema versions.

Most commonly, `jsonschema.validators.validate` is the quickest way to simply
validate a given instance under a schema, and will create a validator
for you.
