Description: ==========
        jsonschema
        ==========
        
        ``jsonschema`` is an implementation of JSON Schema (currently in `Draft 3
        <http://tools.ietf.org/html/draft-zyp-json-schema-03>`_) for Python (supporting
        2.6+ including Python 3).
        
        ::
        
            >>> from jsonschema import validate
        
            >>> # A sample schema, like what we'd get from json.load()
            >>> schema = {
            ...     "type" : "object",
            ...     "properties" : {
            ...         "price" : {"type" : "number"},

            >>> # If no exception is raised by validate(), the instance is valid.
            >>> validate({"name" : "Eggs", "price" : 34.99}, schema)
        
            >>> validate(
            ...     {"name" : "Eggs", "price" : "Invalid"}, schema

            Traceback (most recent call last):
                ...
            ValidationError: 'Invalid' is not of type 'number'
        
        
        Features
        --------
        
        * Support for Draft 3 of the Schema with the exception of
        
            * ``$ref``, and ``extends`` that use ``$ref``\s
        
        * Lazy validation that can iteratively report *all* validation errors.
        
        ::
        
            >>> from jsonschema import Validator
            >>> schema = {
            ...     "type" : "array",
            ...     "items" : {"enum" : [1, 2, 3]},
            ...     "maxItems" : 2,
            ... }
            >>> v = Validator()
            >>> for error in sorted(v.iter_errors([2, 3, 4], schema), key=str):
            ...     print(error)
            4 is not one of [1, 2, 3]
            [2, 3, 4] is too long
        
        * Small and extensible
        
        * Programmatic querying of which properties or items failed validation.
        
        ::
        
            >>> from jsonschema import ErrorTree, Validator
            >>> schema = {
            ...     "type" : "array",
            ...     "items" : {"type" : "number", "enum" : [1, 2, 3]},
            ...     "minItems" : 3,
            ... }
            >>> instance = ["spam", 2]
            >>> v = Validator()
            >>> tree = ErrorTree(v.iter_errors(instance, schema))
        
            >>> sorted(tree.errors)
            ['minItems']
        
            >>> 0 in tree
            True
        
            >>> 1 in tree
            False
        
            >>> sorted(tree[0].errors)
            ['enum', 'type']
        
            >>> print(tree[0].errors["type"].message)
            'spam' is not of type 'number'
        
        
        Schema Versioning
        -----------------
        
        JSON Schema is, at the time of this writing, seemingly at Draft 3, with
        preparations for Draft 4 underway. The ``Validator`` class and ``validate``
        function take a ``version`` argument that you can use to specify what version
        of the Schema you are validating under.
        
        As of right now, Draft 3 (``jsonschema.DRAFT_3``) is the only supported
        version, and the default when validating. Whether it will remain the default
        version in the future when it is superceeded is undecided, so if you want to be
        safe, *explicitly* declare which version to use when validating.
        
        
        Release Notes
        -------------
        
        ``0.6`` fixes the behavior for the ``dependencies`` property, which was
        mis-implemented.
        
        
        Running the Test Suite
        ----------------------
        
        ``jsonschema`` uses the wonderful `Tox <http://tox.readthedocs.org>`_ for its
        test suite. (It really is wonderful, if for some reason you haven't heard of
        it, you really should use it for your projects).
        
        Assuming you have ``tox`` installed (perhaps via ``pip install tox`` or your
        package manager), just run ``tox`` in the directory of your source checkout to
        run ``jsonschema``'s test suite on all of the versions of Python ``jsonschema``
        supports. Note that you'll need to have all of those versions installed in
        order to run the tests on each of them, otherwise ``tox`` will skip (and fail)
        the tests on that version.
