# uncomment the trailing '\' on line 42 and the entirety of line 43 to add
# debug info to happy. the '-i' flag outputs a state diagram of the compiled
# parser into the file `src/Parser.info`, and the '-a -d' flag combo tells
# happy to print state transitions and actions taken during a parse to stderr.
# They are most useful when used together.
