# The second field is the name of the top-level directory for
# this file, relative to the build directory.  E.g., it might
# look like "../../classpath/vm/reference".
# The third field is the file name, like "java/lang/Object.java".
# We do this because it makes splitting for the gcj build much
# cheaper.
