# This script is a wrapper for the jython version shipped with buck.  It is
# intended to be invoked by buck itself during build startup.  It was copied
# from smali which was copied from dx at an unknown and very old version.  The
# most recent one appears consistent, however.

# Set up prog to be the path of this script, including following symlinks,
# and set up progdir to be the fully-qualified pathname of its directory.
