+#Errors and Cancelletion code samples for grpc-ruby
+
+The examples in this directory show use of grpc errors.
+
+On the server side, errors are returned from service
+implementations by raising a certain `GRPC::BadStatus` exception.
+
+On the client side, GRPC errors get raised when either:
+ * the call completes (unary and client-streaming call types)
+ * the response `Enumerable` is iterated through (server-streaming and
+   bidi call types).
+
+## To run the examples here:
+
+Start the server:
+
+```
+> ruby error_examples_server.rb
+```
+
+Then run the client:
+
+```
+> ruby error_examples_client.rb
+```

 these plugins are used to generate gRPC client and server stubs from `.proto` files.

 This directory contains source code for C library (a.k.a the *gRPC C core*) that provides all gRPC's core functionality through a low level API. Libraries in other languages in this repository (C++, Ruby,
 Python, PHP, NodeJS, Objective-C) are layered on top of this library.

+ * NOTE 1:
+ * -------
+ *
+ * Nothing in this file is intended to be modified or adjusted by the
+ * c-ares library user nor by the c-ares library builder.
+ *
+ * If you think that something actually needs to be changed, adjusted
+ * or fixed in this file, then, report it on the c-ares development
+ * mailing list: http://cool.haxx.se/mailman/listinfo/c-ares/
+ *
+ * Try to keep one section per platform, compiler and architecture,
+ * otherwise, if an existing section is reused for a different one and
+ * later on the original is adjusted, probably the piggybacking one can
+ * be adversely changed.
+ *
+ * In order to differentiate between platforms/compilers/architectures
+ * use only compiler built in predefined preprocessor symbols.
+ *
+ * This header file shall only export symbols which are 'cares' or 'CARES'
+ * prefixed, otherwise public name space would be polluted.
+ *
+ * NOTE 2:
+ * -------
+ *
+ * Right now you might be staring at file ares_build.h.dist or ares_build.h,
+ * this is due to the following reason: file ares_build.h.dist is renamed
+ * to ares_build.h when the c-ares source code distribution archive file is
+ * created.
+ *
+ * File ares_build.h.dist is not included in the distribution archive.
+ * File ares_build.h is not present in the git tree.
+ *
+ * The distributed ares_build.h file is only intended to be used on systems
+ * which can not run the also distributed configure script.
+ *
+ * On systems capable of running the configure script, the configure process
+ * will overwrite the distributed ares_build.h file with one that is suitable
+ * and specific to the library being configured and built, which is generated
+ * from the ares_build.h.in template file.
+ *
+ * If you check out from git on a non-configure platform, you must run the
