I have a copy for testing purposes on my machine.  It has an
outrageous number of routines for doing math/statistics/etc.  I will
post more info when I see the documentation later this week.

The only routine that I have used out of it is DGEMM, which looks to
be the same as the version in /lib/libblas.a, and which runs 64-bit
matrix multiplies at a sustained rate of 32 MFLOPS on the Model 320.

If the other routines are optimized as well as DGEMM, then the package
will certainly be worth paying for --- though I don't recall the exact
cost right now....
