######################### We start with some black magic to print on failure.

# Change 1..1 below to 1..last_test_to_print .
# (It may become useful if the test is moved to ./t subdirectory.)

BEGIN {print "1..14\n";}
END {print "not ok 1\n" unless $loaded;}
use MD5;

print "ok 1\n";

######################### End of black magic.
