+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+            The parent figure.
+        rect : (float, float, float, float) or int
+            The axes position, as a ``(left, bottom, width, height)`` tuple or

+        nrows_ncols : (int, int)
+            Number of rows and columns in the grid.
+        ngrids : int or None, default: None
+            If not None, only the first *ngrids* axes in the grid are created.
+        direction : {"row", "column"}, default: "row"
+            Whether axes are created in row-major ("row by row") or
+            column-major order ("column by column").  This also affects the
+            order in which axes are accessed using indexing (``grid[index]``).

+            Padding or (horizontal padding, vertical padding) between axes, in
+            inches.
+        share_all : bool, default: False
+            Whether all axes share their x- and y-axis.  Note that in any case,

+            their y-axis.
+        aspect : bool, default: True
+            Whether the axes aspect ratio follows the aspect ratio of the data
+            limits.
+        label_mode : {"L", "1", "all"}, default: "L"
+            Determines which axes will get tick labels:
+
+            - "L": All axes on the left column get vertical tick labels;
+              all axes on the bottom row get horizontal tick labels.
+            - "1": Only the bottom left axes is labelled.

+            for the entire grid, colorbars only for axes on the "edge"
+            determined by *cbar_location*, or no colorbars.  The colorbars are

+
+    Notes
+    -----
+    The meaning of *bbox_to_anchor* and *bbox_to_transform* is interpreted
+    differently from that of legend. The value of bbox_to_anchor
+    (or the return value of its get_points method; the default is
+    *parent_axes.bbox*) is transformed by the bbox_transform (the default
+    is Identity transform) and then interpreted as points in the pixel
+    coordinate (which is dpi dependent).
+
+    Thus, following three calls are identical and creates an inset axes
+    with respect to the *parent_axes*::
+
+       axins = inset_axes(parent_axes, "30%%", "40%%")
+       axins = inset_axes(parent_axes, "30%%", "40%%",
+                          bbox_to_anchor=parent_axes.bbox)
+       axins = inset_axes(parent_axes, "30%%", "40%%",
+                          bbox_to_anchor=(0, 0, 1, 1),
+                          bbox_transform=parent_axes.transAxes)
+
+    Parameters
+    ----------
+    parent_axes : `matplotlib.axes.Axes`
+        Axes to place the inset axes.
+
+    width, height : float or str
+        Size of the inset axes to create. If a float is provided, it is
+        the size in inches, e.g. *width=1.3*. If a string is provided, it is
+        the size in relative units, e.g. *width='40%%'*. By default, i.e. if
+        neither *bbox_to_anchor* nor *bbox_transform* are specified, those
+        are relative to the parent_axes. Otherwise, they are to be understood
+        relative to the bounding box provided via *bbox_to_anchor*.
+
+    loc : str, default: 'upper right'
+        Location to place the inset axes.  Valid locations are
+        'upper left', 'upper center', 'upper right',
+        'center left', 'center', 'center right',
+        'lower left', 'lower center', 'lower right'.
+        For backward compatibility, numeric values are accepted as well.
+        See the parameter *loc* of `.Legend` for details.
+
+    bbox_to_anchor : tuple or `~matplotlib.transforms.BboxBase`, optional
+        Bbox that the inset axes will be anchored to. If None,
+        a tuple of (0, 0, 1, 1) is used if *bbox_transform* is set
+        to *parent_axes.transAxes* or *parent_axes.figure.transFigure*.
+        Otherwise, *parent_axes.bbox* is used. If a tuple, can be either
+        [left, bottom, width, height], or [left, bottom].
+        If the kwargs *width* and/or *height* are specified in relative units,
+        the 2-tuple [left, bottom] cannot be used. Note that,
+        unless *bbox_transform* is set, the units of the bounding box
+        are interpreted in the pixel coordinate. When using *bbox_to_anchor*
+        with tuple, it almost always makes sense to also specify
+        a *bbox_transform*. This might often be the axes transform
+        *parent_axes.transAxes*.
+
+    bbox_transform : `~matplotlib.transforms.Transform`, optional
+        Transformation for the bbox that contains the inset axes.
+        If None, a `.transforms.IdentityTransform` is used. The value
+        of *bbox_to_anchor* (or the return value of its get_points method)
+        is transformed by the *bbox_transform* and then interpreted
+        as points in the pixel coordinate (which is dpi dependent).
+        You may provide *bbox_to_anchor* in some normalized coordinate,
+        and give an appropriate transform (e.g., *parent_axes.transAxes*).
+
+    axes_class : `~matplotlib.axes.Axes` type, default: `.HostAxes`
+        The type of the newly created inset axes.
+
+    axes_kwargs : dict, optional
+        Keyword arguments to pass to the constructor of the inset axes.
+        Valid arguments include:
+
+        %(Axes:kwdoc)s
+
+    borderpad : float, default: 0.5
+        Padding between inset axes and the bbox_to_anchor.
+        The units are axes font size, i.e. for a default font size of 10 points
+        *borderpad = 0.5* is equivalent to a padding of 5 points.
+
+    Returns

+
+    Parameters
+    ----------
+    parent_axes : `~matplotlib.axes.Axes`
+        Axes to place the inset axes.
+
+    zoom : float
+        Scaling factor of the data axes. *zoom* > 1 will enlarge the
+        coordinates (i.e., "zoomed in"), while *zoom* < 1 will shrink the
+        coordinates (i.e., "zoomed out").
+
+    loc : str, default: 'upper right'
+        Location to place the inset axes.  Valid locations are
+        'upper left', 'upper center', 'upper right',
+        'center left', 'center', 'center right',
+        'lower left', 'lower center', 'lower right'.
+        For backward compatibility, numeric values are accepted as well.
+        See the parameter *loc* of `.Legend` for details.
+
+    bbox_to_anchor : tuple or `~matplotlib.transforms.BboxBase`, optional
+        Bbox that the inset axes will be anchored to. If None,
+        *parent_axes.bbox* is used. If a tuple, can be either
+        [left, bottom, width, height], or [left, bottom].
+        If the kwargs *width* and/or *height* are specified in relative units,
+        the 2-tuple [left, bottom] cannot be used. Note that
+        the units of the bounding box are determined through the transform
+        in use. When using *bbox_to_anchor* it almost always makes sense to
+        also specify a *bbox_transform*. This might often be the axes transform
+        *parent_axes.transAxes*.
+
+    bbox_transform : `~matplotlib.transforms.Transform`, optional
+        Transformation for the bbox that contains the inset axes.
+        If None, a `.transforms.IdentityTransform` is used (i.e. pixel
+        coordinates). This is useful when not providing any argument to
+        *bbox_to_anchor*. When using *bbox_to_anchor* it almost always makes
+        sense to also specify a *bbox_transform*. This might often be the
+        axes transform *parent_axes.transAxes*. Inversely, when specifying
+        the axes- or figure-transform here, be aware that not specifying
+        *bbox_to_anchor* will use *parent_axes.bbox*, the units of which are
+        in display (pixel) coordinates.
+
+    axes_class : `~matplotlib.axes.Axes` type, default: `.HostAxes`
+        The type of the newly created inset axes.
+
+    axes_kwargs : dict, optional
+        Keyword arguments to pass to the constructor of the inset axes.
+        Valid arguments include:
+
+        %(Axes:kwdoc)s
+
+    borderpad : float, default: 0.5
+        Padding between inset axes and the bbox_to_anchor.
+        The units are axes font size, i.e. for a default font size of 10 points
+        *borderpad = 0.5* is equivalent to a padding of 5 points.

+"""
+Axislines includes modified implementation of the Axes class. The
+biggest difference is that the artists responsible for drawing the axis spine,
+ticks, ticklabels and axis labels are separated out from Matplotlib's Axis
+class. Originally, this change was motivated to support curvilinear
+grid. Here are a few reasons that I came up with a new axes class:
+
+* "top" and "bottom" x-axis (or "left" and "right" y-axis) can have
+  different ticks (tick locations and labels). This is not possible
+  with the current Matplotlib, although some twin axes trick can help.
+
+* Curvilinear grid.
+
+* angled ticks.
+
+In the new axes class, xaxis and yaxis is set to not visible by
+default, and new set of artist (AxisArtist) are defined to draw axis
+line, ticks, ticklabels and axis label. Axes.axis attribute serves as
+a dictionary of these artists, i.e., ax.axis["left"] is a AxisArtist
+instance responsible to draw left y-axis. The default Axes.axis contains
+"bottom", "left", "top" and "right".
+
+AxisArtist can be considered as a container artist and has the following
+children artists which will draw ticks, labels, etc.
+
+* line
+* major_ticks, major_ticklabels
+* minor_ticks, minor_ticklabels
+* offsetText
+* label
+
+Note that these are separate artists from `matplotlib.axis.Axis`, thus most
+tick-related functions in Matplotlib won't work. For example, color and
+markerwidth of the ``ax.axis["bottom"].major_ticks`` will follow those of
+Axes.xaxis unless explicitly specified.
+
+In addition to AxisArtist, the Axes will have *gridlines* attribute,
+which obviously draws grid lines. The gridlines needs to be separated
+from the axis as some gridlines can never pass any axis.

+    This helper function launches an async main function that was tagged with

+
+    - The function is a normal function, which handles initializing the event
+      loop, which is then run forever
+    - The function is a coroutine, which needs to be scheduled in the event

+      - There is also the possibility that the function is a normal function

+
+    The function is therefore called unconditionally and scheduled in the event
+    loop if the return value is a coroutine object.
+
+    The reason this is a separate function is to make absolutely sure that all
+    the objects created are garbage collected after all is said and done; we
+    do this to ensure that any exceptions raised in the tasks are collected
+    ASAP.

+    Convert an asyncio coroutine into a function which, when called, is
+    evaluted in an event loop, and the return value returned. This is intented
+    to make it easy to write entry points into asyncio coroutines, which
+    otherwise need to be explictly evaluted with an event loop's
+    run_until_complete.
+
+    If `loop` is given, it is used as the event loop to run the coro in. If it
+    is None (the default), the loop is retreived using asyncio.get_event_loop.
+    This call is defered until the decorated function is called, so that
+    callers can install custom event loops or event loop policies after
+    @autoasync is applied.
+
+    If `forever` is True, the loop is run forever after the decorated coroutine
+    is finished. Use this for servers created with asyncio.start_server and the
+    like.
+
+    If `pass_loop` is True, the event loop object is passed into the coroutine
+    as the `loop` kwarg when the wrapper function is called. In this case, the
+    wrapper function's __signature__ is updated to remove this parameter, so
+    that autoparse can still be used on it without generating a parameter for
+    `loop`.
+
+    This coroutine can be called with ( @autoasync(...) ) or without
+    ( @autoasync ) arguments.

+
+    @autoasync
+    def get_file(host, port):
+        reader, writer = yield from asyncio.open_connection(host, port)
+        data = reader.read()

+
