In this section, we want to give a quick overview of available software, subdivided in categories. We are not going to describe every piece of software in detail, but this overview will get notes added about the local setup, and links to the documentation of the package.
An attempt like this is bound to be out-of-date, because software changes rapidly. Please help us to help you; if a piece of software is not documented here, drop us a note. And if something that is documented here appears to be missing, please tell us; perhaps it was dropped by mistake, or it was replaced by another package, and we will do our best to get it back, or document its removal.
