# NumPy static imports for Cython
#
# If any of the PyArray_* functions are called, import_array must be
# called first.
#
# This also defines backwards-compatability buffer acquisition
# code for use in Python 2.x (or Python <= 2.5 when NumPy starts
# implementing PEP-3118 directly).
#
# Because of laziness, the format string of the buffer is statically
# allocated. Increase the size if this is not enough, or submit a
# patch to do this properly.
