-# Example of a (10000,5000) LDPC code with varying numbers of check per bit,
-# tested on Additive White Gaussian Noise channels with noise standard 
-# deviations varying from 0.80 to 0.95.  The code has 20% columns with two 
-# check bits, 70% columns with three check bits, and 10% columns with seven
-# check bits.
-#
-# Testing is done by transmitting random messages, with pipes used so that
-# intermediate files are avoided.  Decoding is done using a maximum of 250
-# iterations of probability propagation.
-
-set -e  # Stop if an error occurs
-set -v  # Echo commands as they are read
