# This directory is set up so that lex and bison should not have
# to be run to generate C files, since the C files have already
# been checked in and are present. This eliminates the need to run
# them on systems where those tools may not be present. If you wish
# to run either of them to regenerate their output files, remove
# the output files first. This prevents these tools from being run
# again if the output files are already present.
