# Written by Aleksandar Samardzic <asamardzic@gmail.com>
# Updated up to 1.16.6 by Serban Udrea <S.Udrea@gsi.de>
#
# Added support for building with debugging symbols (S. Udrea)
#
# LIBDIRSUFFIX is now needed to set the proper path for
# UMFPACK (S. Udrea)
#
# Since UMFPACK is not used anymore by scipy but by the optional package
# scikit-umfpack, the configuration of this and the corresponding AMD library
# is now optional. One has to set NO_UMFPACK to "no" to create the apropriate
# configuration file before building numpy. (S. Udrea)
#
# Added the possibility to force numpy to link to different kinds of the
# ATLAS library (S. Udrea)
#
# Thanks go to Pedro Ribeiro Mendes Júnior for help with the upgrade to 1.14.3.
