# This script checks the current revision of the code against the
# previous release of the FIPS code. While wolfSSL and wolfCrypt
# may be advancing, they must work correctly with the last tested
# copy of our FIPS approved code.
#
# This should check out all the approved flavors. The command line
# option selects the flavor. The keep option keeps the output
# directory.

# These variables may be overridden on the command line.
