# This is a serial build of NEURON without Python or other bindings.
# Both the MPI builds and Python bindings require NEURON to be already
# installed in the system---they are build as post-installation hooks. So, we
# first package a serial version of NEURON and then package those separately
# after using this package as a BR
%global _description %{expand:
NEURON is a simulation environment for modeling individual neurons and networks
of neurons. It provides tools for conveniently building, managing, and using
models in a way that is numerically sound and computationally efficient. It is
particularly well-suited to problems that are closely linked to experimental
data, especially those that involve cells with complex anatomical and
biophysical properties.

This package is currently built without GUI (iv) support.
It does not include MPI support.

Please install the %{name}-devel package to compile nmodl files and so on.
