+
+Introduction
+------------
+
+:code:`cythonizer.py` is a script that will attempt to
+automatically convert one or more :code:`.py` and :code:`.pyx` files into
+the corresponding compiled :code:`.pyd | .so` binary modules
+files. Example::
+
+    $ python cythonizer.py myext.pyx
+
+:code:`pip install cythonizer` will automatically create an
+executable script in your :code:`Scripts/` folder, so you
+should be able to simply::
+
+    $ cythonizer myext.py
+
+or even::
+
+    $ cythonizer *.pyx
+
+You can type::
+
+    $ cythonizer -h
+
+to obtain the following CLI::
+
+    usage: cythonizer.py [-h] [--annotation] [--numpy-includes]
+                         [--debugmode] filenames [filenames ...]
+
+    positional arguments:
+    filenames         .py and .pyx files only
+
+    optional arguments:
+    -h, --help        show this help message and exit
+    --annotation      (default: False)
+    --numpy-includes  (default: False)
+    --debugmode       (default: False)
+
+
+- :code:`--annotation` will create the HTML Cython annotation file.
+- :code:`--numpy-includes` will add the numpy headers to the build command.
+- Compiler flags :code:`-O2 -march=native` are automatically passed to the compiler.
