As you can guess from the version number this software is still somewhat unstable. The implementations may be extremely buggy, the APIs can change. You have been warned. NOTE: the releases 0.003...0.005 do not contain all the algorithms that 0.001 (and the never-publicly-released 0.002) had. They are under reconstruction as the data structures underwent a major overhaul in 0.003. 0.005 is essentially the same as 0.004, it was just Perl 5.005_5X-proofed.
