    Given a DataSource, generate a dictionary that may be used
    for invoking the LayerMapping utility.

    Keyword Arguments:
     `geom_name` => The name of the geometry field to use for the model.

     `layer_key` => The key for specifying which layer in the DataSource to use;
       defaults to 0 (the first layer).  May be an integer index or a string
       identifier for the layer.

     `multi_geom` => Boolean (default: False) - specify as multigeometry.

    Given a data source (either a string or a DataSource object) and a string
    model name this function will generate a GeoDjango model.

    Usage:

    >>> from django.contrib.gis.utils import ogrinspect
    >>> ogrinspect('/path/to/shapefile.shp','NewModel')

    ...will print model definition to stout

    or put this in a Python script and use to redirect the output to a new
    model like:

    $ python generate_model.py > myapp/models.py

    # generate_model.py
    from django.contrib.gis.utils import ogrinspect
    shp_file = 'data/mapping_hacks/world_borders.shp'
    model_name = 'WorldBorders'

    print(ogrinspect(shp_file, model_name, multi_geom=True, srid=4326,
                     geom_name='shapes', blank=True))

    Required Arguments
     `datasource` => string or DataSource object to file pointer

     `model name` => string of name of new model class to create

    Optional Keyword Arguments
     `geom_name` => For specifying the model name for the Geometry Field.
       Otherwise will default to `geom`

     `layer_key` => The key for specifying which layer in the DataSource to use;
       defaults to 0 (the first layer).  May be an integer index or a string
       identifier for the layer.

     `srid` => The SRID to use for the Geometry Field.  If it can be determined,
       the SRID of the datasource is used.

     `multi_geom` => Boolean (default: False) - specify as multigeometry.

     `name_field` => String - specifies a field name to return for the
       __str__() method (which will be generated if specified).

     `imports` => Boolean (default: True) - set to False to omit the
       `from django.contrib.gis.db import models` code from the
       autogenerated models thus avoiding duplicated imports when building
       more than one model by batching ogrinspect()

     `decimal` => Boolean or sequence (default: False).  When set to True
       all generated model fields corresponding to the `OFTReal` type will
       be `DecimalField` instead of `FloatField`.  A sequence of specific
       field names to generate as `DecimalField` may also be used.

     `blank` => Boolean or sequence (default: False).  When set to True all
       generated model fields will have `blank=True`.  If the user wants to
       give specific fields to have blank, then a list/tuple of OGR field
       names may be used.

     `null` => Boolean (default: False) - When set to True all generated
       model fields will have `null=True`.  If the user wants to specify
       give specific fields to have null, then a list/tuple of OGR field
       names may be used.

    Note: Call the _ogrinspect() helper to do the heavy lifting.
