# "binaries" is an empty file that's newer than the executables in
# this directory.  It is used as an empty target, and records the time
# at which this run was initiated.  (It is 'built' from the
# executables by copying them into the current directory, and touching
# 'binaries'.  This prevents new binaries from inadvertantly being
# copied into archived benchmark directories.

# Note that this makefile recursively calls itself... there must be a
# better way.  The problem is that we need to prevent make from
# realizing that we build the .exe from the original binary.
# Otherwise, it would copy over the archived binary when we recompile...
