+// Similarly, start_read can only be called after the READ event for any

+This is a generic Reactive Extensions library for Objective-C, created to ease
+the implementation of the gRPC Objective-C runtime.
+
+It has no dependencies on gRPC nor other libraries, and should eventually be
+moved under its own GitHub project.
+
+If you're trying to get started on the library, you might want to first read
+GRXWriter.h and then GRXWriteable.h.

+GRPC Python
+=========
+
+The Python facility of GRPC.
+
+
+Prerequisites
+-----------------------
+
+Python 2.7, virtualenv, pip, libprotobuf-dev, and libprotoc-dev.
+
+
+Building from source
+----------------------
+
+- Build the GRPC core
+E.g, from the root of the grpc [git repo](https://github.com/google/grpc)
+```
+$ make shared_c static_c
+```
+
+- Use build_python.sh to build the Python code and install it into a virtual environment
+```
+$ tools/run_tests/build_python.sh
+```
+
+
+Testing
+-----------------------
+
+- Use run_python.sh to run GRPC as it was installed into the virtual environment
+```
+$ tools/run_tests/run_python.sh
+```
