+Calculate the bit error rate (BER) or the symbol error rate (SER) over a number of samples given by the window size. \
+The actual window size will start at size one and grow to the full window size as new samples arrive. \
+Once the window has reached full size, old samples are shifted out of the window and new samples shfited in.
+
+The error block compares the input byte stream to the reference byte stream. \
+For example, the reference byte stream could be the input to a modulator, \
+and the input byte stream could be the output of a modulator.
+
+Each byte in the incoming stream represents one symbol. \
+The bits per symbol parameter is only useful for calculating the BER.

+The options block sets special parameters for the flow graph. \
+Only one option block is allowed per flow graph.
+
+Title, author, and description parameters are for identification purposes.
+
+The window size controls the dimensions of the flow graph editor. \
+The window size (width, height) must be between (300, 300) and (2048, 2048).
+
+The generate options controls the type of code generated. \
+Non-graphical flow graphs should avoid using graphical sinks or graphical variable controls.
+
+The id of this block determines the name of the generated file and the name of the class. \
+For example, an id of my_block will generate the file my_block.py and class my_block(gr....
+
+The category parameter determines the placement of the block in the block selection window. \

+##################################################
+# XMLRPC example
+##################################################
+
+XMLRPC allows software to make remote function calls over http.
+In the case of GRC, one can use XMLRPC to modify variables in a running flow graph.
+See http://www.xmlrpc.com/
+
+--- Server Example ---
+Place an "XMLRPC Server" block inside of any flow graph.
+The server will provide set functions for every variable in the flow graph.
+If a variable is called "freq", the server will provide a function set_freq(new_freq).
+Run the server example and experiment with the example client script.
+
+-- Client Example --
+The "XMLRPC Client" block will give a variable control over one remove function.
+In the example client, there is one client block and gui control per variable.
+This technique can be used to remotely control a flow graph, perhaps running on a non-gui machine.
