%global desc %{expand: \
Brian2 is a simulator for spiking neural networks available on almost all
platforms. The motivation for this project is that a simulator should not only
save the time of processors, but also the time of scientists.

It is the successor of Brian1 and shares its approach of being highly flexible
and easily extensible. It is based on a code generation framework that allows
to execute simulations using other programming languages and/or on different
devices.

Please report issues to the github issue tracker
(https://github.com/brian-team/brian2/issues) or to the brian support mailing
list (http://groups.google.com/group/briansupport/)

Documentation for Brian2 can be found at http://brian2.readthedocs.org}
