I have corrected the docs in: http://www.pytables.org/trac/changeset/3714/trunk Thanks for (indirectly ;-) bringing this to my attention, Francesc -- http://mail.python.org/mailman/listinfo/python-list

ink) in the universe enter directly in the domain of random/chaotic ;) IMO, the wisest path should be recognizing the strengths (and weaknesses) of each approach and use whatever fits better to your needs.
