# This script is used to format sentences for a predictor network.
# It assumes you are using a 1-bit per word encoding.
# The first command-line argument is a vocab list which should contain
# the words in your language, one per line.
# The second argument is the name of a file containing sentences, one per line.
# If there is no second argument, they will be read from stdin.
# Note that the first input to the network for each sentence will be a special
# START symbol and the first output is the prediction for the first word.
