Hello, the link
http://plan9.bell-labs.com/sys/doc/troff.html on the web site http://plan9.bell-labs.com/wiki/plan9/Using_troff/index.html does not work. There is a lot of information about troff but I am interested in special plan9 troff extensions. Is there someone maintaining plan9 troff? It seems to have bugs and I'd like to investigate that. --Carsten
