[Numpy-discussion] ANN: HDF5 for Python 2.5.0

[Nathaniel Smith]

(Off-list)

Congrats! Also btw, you might want to switch to a new subject line format
for these emails -- the mention of Python 2.5 getting hdf5 support made me
do a serious double take before I figured out what was going on, and 2.6
and 2.7 will be even worse :-)
