This library develops some of the basic concepts and results of general topology. The library depends on my ZornsLemma contribution. The provided makefile expects compiled files to be present in ../ZornsLemma; if you have them somewhere else, first run coq_makefile -R /path/to/ZornsLemma ZornsLemma -R . Topology *.v > makefile before running make.
