+	Soon before official Go 1.1, we understand supporting Go in a fork() heavy
+	environment was not blessed by the Go community.
+
+	Instead of completely dropping support for Go, we studied how the gccgo project works and we
+	decided it was a better approach for uWSGI.
+
+	This new plugin works by initializing a new "go runtime" after each fork().
+
+	The runtime calls the Go main function (developed by the user), and pass the whole
+	uWSGI control to it.
+	
+	the uwsgi.Run() go function directly calls the uwsgi_takeover() function (it automatically
+	manages mules, spoolers and workers)
+
+	As well as before each core maps to a goroutine mapped to a real pthread. (goroutines called
+	from your apps are native goroutines)

+This is a bit convoluted, but you run it (so far) this way:
+
+You have to compile PyPy with strange options. I'll explain them below.
+In the pypy checkout, run:
+
+  ./rpython/bin/rpython -Ojit --shared --gcrootfinder=shadowstack pypy/goal/targetpypystandalone
+
+Options:
+
+  -Ojit - standard PyPy build with JIT
+  --shared - as expected, creates a .so
+  --gcrootfinder - on linux, the default rootfinder is asmgcc which has trouble
+                   with position independent code. This option is not needed
+                   on OS X or windows.
+
+If for some strange/dangerous/wrong reason your uWSGI binary is linked with cpython you could have name collisions
+with pypy cpyext. In such crazy case you can remove cpyext support with:
+
+  ./rpython/bin/rpython -Ojit --shared --gcrootfinder=shadowstack pypy/goal/targetpypystandalone --withoutmod-cpyext
+
+By default the pypy uWSGI plugin will load the libpypy-c.so library. You should have it in the LD_LIBRARY_PATH, otherwise you can set its path
+with --pypy-lib option (pass an absolute path to it)
+
+You have to specify the pypy home too, you can use the --pypy-home option or the PYPY_HOME var
+
+   PYPY_HOME=/home/user/pypy/lib_pypy uwsgi --pypy-lib /opt/pypy/libpypy-c.so --http-socket :9090 --pypy-wsgi werkzeug.testapp:test_app
+
+
+The funny part about the uWSGI pypy plugin is that it is mainly written in python. The pypy_setup.py script is linked to the plugin, but you can override
+it with the --pypy-setup option
