No, numarray is still a *requeriment* for compiling PyTables; NumPy
and Numeric are *not needed* at all for compilation.

However, if they are present (I mean, at run-time, not at
compile-time), they can be used both to provide input data to be
written to disk and to get output data read from disk. You can even
have different objects with different flavors (currently "numarray",
"numpy", "numeric" or "python") in the same PyTables file, so that you
can retrieve different objects (numarray, Numpy, Numeric or pure
Python) in the same session depending on its flavor (but of course,
this is not for the faint-hearted ;-). It is the magic of array


that allows doing this in a very efficient manner.
