|   ast        1     AST construction in parser

ast
Abstract-Syntax Tree construction. With this option set to 1, any +> or *> action operators in your grammar will cause the generated parser to build an AST. In some cases you might want to disable the AST construction for debugging or creating a syntax checker only. So, just set ast=0.

|   m         0     Minimize parser-table size.

m
This may give a decrease in size of the parser tables by 10% or more.

|   o         0     Optimize parser-table speed.

o
This does chain-reduction elimination in the states.
