Random sentence generator from context-free grammars.

Usage:

python sentence_generator.py --grammar=grammar.txt --num_sentences=10

Grammar file:

Grammar file must follow a specific format. The first line should be the starting symbol of the grammar. The following lines are the production rules of the grammar. The set of terminal and non-terminal symbols are inferred from the grammar.

Each production rule must have the format X -> A B .. C The left side should be a single non-terminal symbol. The right side should be a list of symbols (terminal or non-terminal), separated by spaces.
