+
+PyPy has a very minimal and a very strange embedding interface, based on
+the usage of `cffi`_ and the philosophy that Python is a better language in C.
+It was developed in collaboration with Roberto De Ioris from the `uwsgi`_
+project. The `PyPy uwsgi plugin`_ is a good example of usage of such interface.
+
+The first thing that you need, that we plan to change in the future, is to
+compile PyPy yourself with an option ``--shared``. Consult the
+`how to compile PyPy`_ doc for details. That should result in ``libpypy.so``
+or ``pypy.dll`` file or something similar, depending on your platform. Consult
+your platform specification for details.
+
+The resulting shared library has very few functions that are however enough
+to make a full API working, provided you'll follow a few principles. The API
+is:
+
+.. function:: void pypy_init(int need_threads);
+
+ This is a function that you have to call (once) before calling anything.
+ It initializes the RPython/PyPy GC and does a bunch of necessary startup
+ code. This function cannot fail. Pass 1 in case you need thread support, 0
+ otherwise.
+
+.. function:: long pypy_setup_home(char* home, int verbose);
+
+ This is another function that you have to call at some point, without
+ it you would not be able to find the standard library (and run pretty much
+ nothing). Arguments:
+
+ * ``home``: null terminated path
+
+ * ``verbose``: if non-zero, would print error messages to stderr
+
+ Function returns 0 on success or 1 on failure, can be called multiple times
+ until the library is found.
+
+.. function:: int pypy_execute_source(char* source);
+
+ Execute the source code given in the ``source`` argument. Will print
+ the error message to stderr upon failure and return 1, otherwise returns 0.
+ You should really do your own error handling in the source. It'll acquire
+ the GIL.
+
+.. function:: void pypy_thread_attach(void);
+
+ In case your application uses threads that are initialized outside of PyPy,
+ you need to call this function to tell the PyPy GC to track this thread.
+ Note that this function is not thread-safe itself, so you need to guard it
+ with a mutex. Do not call it from the main thread.
+
+Simple example
+--------------
+
+Note that this API is a lot more minimal than say CPython C API, so at first
+it's obvious to think that you can't do much. However, the trick is to do
+all the logic in Python and expose it via `cffi`_ callbacks. Let's assume
+we're on linux and pypy is put in ``/opt/pypy`` (a source checkout) and
+library is in ``/opt/pypy/libpypy-c.so``. We write a little C program
+(for simplicity assuming that all operations will be performed::
+
+ #include "include/PyPy.h"
+ #include <stdio.h>
+
+ const char source[] = "print 'hello from pypy'";
+
+ int main()
+ {
+ int res;
+
+ rpython_startup_code();
+ res = pypy_execute_source((char*)source);
+ if (res) {
+ printf("Error calling pypy_execute_source!\n");
+ }
+ return res;
+ }
+
+If we save it as ``x.c`` now, compile it and run it with::
+
+ fijal@hermann:/opt/pypy$ gcc -o x x.c -lpypy-c -L.
+ fijal@hermann:~/src/pypy$ LD_LIBRARY_PATH=. ./x
+ hello from pypy
+
+Worked!
+
+More advanced example
+---------------------
+
+Typically we need something more to do than simply execute source. The
following
+is a fully fledged example, please consult cffi documentation for details.
