+On my Athlon 64 2.4 GHz workstation (running Linux), the "fec" command-line
+tool encoded a 160 MB file with m=100, k=94 (about 6% redundancy) in 3.9
+seconds, where the "par2" tool encoded the file with about 6% redundancy in
+27 seconds.  "fec" encoded the same file with m=12, k=6 (100% redundancy) in
+4.1 seconds, where par2 encoded it with about 100% redundancy in 7 minutes

+The underlying C library in benchmark mode encoded from a file at about 
+4.9 million bytes per second and decoded at about 5.8 million bytes per second.

+On Peter's fancy Intel Mac laptop (2.16 GHz Core Duo), it encoded from a file

+On my old PowerPC G4 867 MHz Mac laptop, it encoded from a file at about 1.3
