# reduce_one.py reducer testfile
#   Reduce a single standalone test via the specified reducer, and add the
#   fully reduced result back to the corpus.  Uses configuration state from
#   config.json
#
#   IMPORTANT: Assumes (but does not check) that binaries in build-dir
#   correspond to a build of the source at revision.
