-Guile bindings
-==============
-
-This library includes experimental bindings bring efficient immutable
-vectors for the `GNU Guile`_ Scheme implementation.  The interface is
-somewhat **incomplete**, but you can already do something interesting
-things like:
-
-.. literalinclude:: ../extra/guile/example.scm
-   :language: scheme
-   :start-after: intro/start
-   :end-before:  intro/end
-..
-
-    **Do you want to help** making these bindings complete and production
-    ready?  Drop a line at `immer@sinusoid.al
-    <mailto:immer@sinusoid.al>`_ or `open an issue on Github
-    <https://github.com/arximboldi/immer>`_
-
-.. _GNU Guile: https://www.gnu.org/software/guile/
-
-Installation
-------------
-
-.. highlight:: sh
-
-To install the software, you need `GNU Guile 2.2
-<https://www.gnu.org/software/guile/download/>`_.  Then you have to
-`clone the repository <https://github.com/arximboldi/immer>`_ and
-inside the repository do something like::
-
-    mkdir build; cd build
-    cmake .. -DCMAKE_BUILD_TYPE=Release \
-             -DGUILE_EXTENSION_DIR="<somewhere...>"
-    make guile
-    cp extra/guile/libguile-immer.so "<...the GUILE_EXTENSION_DIR>"
-    cp extra/guile/immer.scm "<somewhere in your GUILE_LOAD_PATH>"
-
-Benchmarks
-----------
-
-The library includes some quick and dirty benchmarks that show how
-these vectors perform compared to *mutable vectors*, *lists*, and
-*v-lists*.  Once you have installed the library, you may run them by
-executing the following in the project root::
-
-    guile extra/guile/benchmark.scm
-
-This is the output I get when running those:
-
-.. code-block:: scheme
-   :name: benchmark-output
