# Generate parser (default target)
#
# when generating the parser with debug options it will look like:
#   make JAVACC_FLAGS=-debug_parser
#  or
#   make JAVACC_FLAGS="-debug_parser -debug_lookahead"
#
# Available debug options:
#  -debug_parser
#  -debug_token_manager
#  -debug_lookahead
#
# For other javacc settings / options consult the documentation of javacc.
