     They are all exported by the tags ':consts' and ':all'.
 
+BENCHMARKS
+    The following timings were obtained by running the "samples/bench.pl"
+    script with perl 5.8.8 on a Core 2 Duo 2.66GHz machine. The "_pp"
+    entries are the pure Perl versions, while "_bv" are Bit::Vector
+    versions.

 CAVEATS
     Please report architectures where we can't use the alignment as the move
     unit. I'll add exceptions for them.
