   Format: MarkdownItex[pi-base](http://topology.jdabbs.com/) is an interactive version of Counterexamples in Topology, it's quite nice to play with. It contains some basic automated theorem proving to find counterexamples to a list of properties or combine known results. I've added a few links back-and-forth between the nlab and pi-base, but this is just an experiment.
