# If we want to get rid of all flex/bison generated files, we need to use

# that operation is to define maintainer-clean-local target. However,
# make maintainer-clean also removes Makefile, so running configure script
# is required. To make it easy to rebuild flex/bison without going through
# reconfigure, a new target parser-clean has been added.
