-#
-# Data flatening
-# ----------------
-#
-# Here is some example data, which would eventually be sent along with a post request :
-#
-#     >>> inpt = urlencode([
-#     ...     ('key1', 'bla1'),
-#     ...     ('key2', 'blo1'), ('key2', 'blo2'),
-#     ... ])
-#
-# Default behaviour for :class:`parsers.FormParser`, is to return a single value for each parameter :
-#
-#     >>> (data, files) = FormParser(some_view).parse(StringIO(inpt))
-#     >>> data == {'key1': 'bla1', 'key2': 'blo1'}
-#     True
-#
-# However, you can customize this behaviour by subclassing :class:`parsers.FormParser`, and overriding :meth:`parsers.FormParser.is_a_list` :
-#
-#     >>> class MyFormParser(FormParser):
-#     ...
-#     ...     def is_a_list(self, key, val_list):
-#     ...         return len(val_list) > 1
-#
-# This new parser only flattens the lists of parameters that contain a single value.
-#
-#     >>> (data, files) = MyFormParser(some_view).parse(StringIO(inpt))
-#     >>> data == {'key1': 'bla1', 'key2': ['blo1', 'blo2']}
-#     True
-#
-# .. note:: The same functionality is available for :class:`parsers.MultiPartParser`.
-#
-# Submitting an empty list
-# --------------------------
-#
-# When submitting an empty select multiple, like this one ::
-#
-#     <select multiple="multiple" name="key2"></select>
-#
-# The browsers usually strip the parameter completely. A hack to avoid this, and therefore being able to submit an empty select multiple, is to submit a value that tells the server that the list is empty ::
-#
-#     <select multiple="multiple" name="key2"><option value="_empty"></select>
-#
-# :class:`parsers.FormParser` provides the server-side implementation for this hack. Considering the following posted data :
-#
-#     >>> inpt = urlencode([
-#     ...     ('key1', 'blo1'), ('key1', '_empty'),
-#     ...     ('key2', '_empty'),
-#     ... ])
-#
-# :class:`parsers.FormParser` strips the values ``_empty`` from all the lists.
-#
-#     >>> (data, files) = MyFormParser(some_view).parse(StringIO(inpt))
-#     >>> data == {'key1': 'blo1'}
-#     True
-#
-# Oh ... but wait a second, the parameter ``key2`` isn't even supposed to be a list, so the parser just stripped it.
-#
-#     >>> class MyFormParser(FormParser):
-#     ...
-#     ...     def is_a_list(self, key, val_list):
-#     ...         return key == 'key2'
-#     ...
-#     >>> (data, files) = MyFormParser(some_view).parse(StringIO(inpt))
-#     >>> data == {'key1': 'blo1', 'key2': []}
-#     True
-#
-# Better like that. Note that you can configure something else than ``_empty`` for the empty value by setting :attr:`parsers.FormParser.EMPTY_VALUE`.
