`.
`optimized`
should the optimizer be enabled? Default is `True`.
`undefined`
:class:`Undefined` or a subclass of it that is used to represent
undefined values in the template.
`finalize`
A callable that finalizes the variable. Per default no finalizing
is applied.
`autoescape`
If set to true the XML/HTML autoescaping feature is enabled.
For more details about auto escaping see
:class:`~jinja2.utils.Markup`.
`loader`
The template loader for this environment.
`cache_size`
The size of the cache. Per default this is ``50`` which means
that if more than 50 templates are loaded the loader will clean
out the least recently used template. If the cache size is set to
``0`` templates are recompiled all the time, if the cache size is
``-1`` the cache will not be cleaned.
`auto_reload`
Some loaders load templates from locations where the template
sources may change (ie: file system or database). If
`auto_reload` is set to `True` (default) every time a template is
requested the loader checks if the source changed and if yes, it
will reload the template. For higher performance it's possible to
disable that.
`bytecode_cache`
If set to a bytecode cache object, this object will provide a
cache for the internal Jinja bytecode so that templates don't
have to be parsed if they were not changed.
See :ref:`bytecode-cache` for more information.

the load name of the template after it was joined using
:meth:`join_path` if necessary, not the filename on the file system.
the `filename` parameter is the estimated filename of the template on
the file system. If the template came from a database or memory this
can be omitted.
The return value of this method is a python code object. If the `raw`
parameter is `True` the return value will be a string with python
code equivalent to the bytecode returned otherwise. This method is
mainly used internally.

s A handy helper method that returns a callable that accepts keyword
arguments that appear as variables in the expression. If called it
returns the result of the expression.
This is useful if applications want to use the same rules as Jinja
in template "configuration files" or similar situations.
Example usage:
>>> env = Environment()
>>> expr = env.compile_expression('foo == 42')
>>> expr(foo=23)
False
>>> expr(foo=42)
True
Per default the return value is converted to `None` if the
expression returns an undefined value. This can be changed
by setting `undefined_to_none` to `False`.
>>> env.compile_expression('var')() is None
True
>>> env.compile_expression('var', undefined_to_none=False)()
Undefined

and is used to evaluate it.
Normally the template object is generated from an :class:`Environment` but
it also has a constructor that makes it possible to create a template
instance directly using the constructor. It takes the same arguments as
the environment constructor but it's not possible to specify a loader.
Every template object has a few methods and members that are guaranteed
to exist. However it's important that a template object should be
considered immutable. Modifications on the object are not supported.
Template objects created from the constructor rather than an environment
do have an `environment` attribute that points to a temporary environment
that is probably shared with other templates created with the constructor
and compatible settings.
>>> template = Template('Hello {{ name }}!')
>>> template.render(name='John Doe')
u'Hello John Doe!'
>>> stream = template.stream(name='John Doe')
>>> stream.next()
u'Hello John Doe!'
>>> stream.next()

A dict, a dict subclass or some keyword arguments. If no arguments
are given the context will be empty. These two calls do the same::
template.render(knights='that say nih')
template.render({'knights': 'that say nih'})
This will return the rendered template as unicode string.

s A template stream works pretty much like an ordinary python generator
but it can buffer multiple items to reduce the number of total iterations.
Per default the output is unbuffered which means that for every unbuffered
instruction in the template one unicode string is yielded.
If buffering is enabled with a buffer size of 5, five items are combined
into a new unicode string. This is mainly useful if you are streaming
big templates to a client via WSGI which flushes after each iteration.
